Will this presser foot fit my machine? Four things to check, and what "universal" actually covers
After this page you will be able to accept or reject a specific presser foot for your specific machine — or name exactly which spec you still need to look up, and where it is written. It also covers the common case: what to do when the listing says only "fits most low shank machines" and gives you nothing else.
A presser foot fits when four properties of your machine line up with what the listing says. Hook and bobbin type. Maximum stitch width. How the foot attaches. Shank height. Establish all four and most listings answer themselves.
"Universal" almost always means one narrow thing: a low-shank machine fitted with a snap-on ankle. Read a real example. Madam Sew's 32-piece "Ultimate Presser Foot Set" — sold as universal — states in its own fit line that it "Fits on low shank models of these brand machines," names a dozen brands, and describes the contents as "snap-on feet designed to fit most low-shank machines." The same listing then publishes its own exceptions: the Pfaff Creative, the Husqvarna 300 and "certain Janome models" have "not been a great match," and misaligned feet "can risk needle breakage." That is one seller's stated specification, not a test result. The general rule — that "universal" means low-shank snap-on rather than every machine — is inferred from that listing read against Madam Sew's own explainer on shanks. Read the fit line on the specific listing rather than the word.
No cross-brand chart covers these four makers. Janome, Husqvarna Viking, BERNINA and Brother each publish a different and mutually untranslatable system for encoding fit, so the useful skill is reading your own maker's system rather than trusting a category name. That is an inference from comparing those four makers' published documents, not a claim any of them makes.
The four properties, in the order a manufacturer asks them
Janome's one-page identification guide poses three questions, in this order, and the order is theirs rather than a convention:
- Where do you insert your bobbin? Janome gives two answers: a horizontal rotary hook bobbin, or a front-loading vertical oscillating hook.
- What is the maximum stitch width? Janome gives three answers on that sheet: 9 mm, 7 mm or 5 mm.
- Shank height: low or high.
Attachment method is the fourth property, and Janome's own footnote is the reason. The guide says shank height "is only needed if you require a presser foot that attaches directly to the presser foot bar." A snap-on foot never touches the presser bar. It clips to an ankle, and the ankle is the part that screws on. So the first question about any foot is which of those two it is, because the answer decides whether check four even applies.
Finding each one on your own machine
Hook and bobbin. Inferred from the two illustrations on Janome's sheet, which carry labels but no descriptive text: dropped in through a plate on the flat bed is a horizontal rotary hook; loaded through a door on the front, into a case you lift out, is a front-loading vertical oscillating hook. You can confirm which one you have against your own machine in a few seconds. If you are also buying bobbins, that same observation starts the bobbin question — see the bobbin guide.
Maximum stitch width. Many machines publish it. On Janome's own model pages the field is named "Maximum Stitch Width" — the MyStyle100 page lists 5mm, alongside a separate "Hook Type" field reading "Top Loading Full Rotary Hook Bobbin." Those are the exact labels to look for in your manual or on the maker's model page. If you cannot find them, Janome publishes a test: set the machine to its maximum stitch width, run a zig-zag, then measure the resulting width. Two minutes, no parts required.
Shank height. Measure it. One retailer's method is to put the foot down and measure from the bed of the machine to the center of the thumbscrew: half an inch is low shank, more than an inch is high. The commonly cited encyclopaedia figures are 0.5 in (13 mm) for low and 1 in (25 mm) for high, measured from the bottom of the foot to the center of the thumbscrew. Those two sources describe slightly different reference points and arrive at the same numbers, so treat them as approximate. Neither is a manufacturer specification. The most reliable check is comparison against the foot already on your machine.
Attachment method. Does the foot come off by loosening a thumbscrew, or by pressing a release? On a Brother HC1850, Brother's instruction is to press the black button at the back of the presser foot holder; a replacement foot's pin then snaps into the shank as you lower the presser foot lever. If your machine works that way, the holder is an ankle and you are shopping for snap-on feet.
When the listing tells you nothing
This is the common case. You are looking at a listing that says "fits most low shank machines" and nothing else — no category letter, no group number, no width. That line answers exactly one of the four checks: the foot will physically clip onto a low-shank snap-on ankle. It tells you nothing about the width of the needle opening, nothing about your hook, and nothing about whether the seller has ever seen your model. Two checks are simply unanswered, and you have to answer them yourself. Look up your own maximum stitch width, in millimeters, before you buy. Then hand-turn the wheel before you sew, at the widest stitch you intend to use. If your machine is high shank, or the listing names your brand among its exceptions, stop there instead.
Adapters are the usual escape hatch, and worth knowing about before you conclude a foot is out. A snap-on adapter screws on in place of your existing presser foot holder — Madam Sew, which sells them, describes it as replacing the presser foot holder with the adapter, after which the feet clip on and off. Adapters are sold for high-shank machines and for BERNINA as well as for low shank. An adapter changes the attachment answer only. It does not change your hook type or your maximum stitch width, so the other checks still stand.
What a manufacturer's real fit chart looks like
Janome's global accessories catalog (Apr. 2026 edition) assigns models to a lettered category and gives each category its hook type, maximum zigzag width, shank and AcuFeed status. Each foot in the catalog then lists the letters it fits. This is a worked example of the four-axis check in practice. The ten sewing-machine categories are below. The catalog's other letters cover embroidery-only machines (B), overlockers (H), CoverPro models (I), high-speed straight-stitch models (J — 1600P, HD9P, HD9 QCP), the FM725 needle-punching machine (K), multi-needle models (L — MB-4, MB-4S, MB-7) and combined overlock and coverstitch models (M — 1200D, 1100D). If yours is a J, look it up under that letter rather than in the table here: Janome leaves the width, shank and AcuFeed columns blank for every one of those letters, and a straight-stitch-only machine has no zigzag width to sort by.
| Category | Janome's description | Max. zigzag width | Shank | AcuFeed | Example models listed |
|---|---|---|---|---|---|
| A | Embroidery & Sewing models (7 mm width) and SKYLINE S3 | 7 mm | High | No | SKYLINE S3, MC9000, MC10000/10001 |
| C | Computer models with AcuFeed system (7 mm width) and MC6500P | 7 mm | High | Yes | HMC7700QCP, MC6600P, MC6500P |
| D | Computer models (7 mm/5 mm width) | 7 mm | Low | No | MC5200, MC4900QC, DC4030 |
| E | Top-loading (Horizontal Rotary Hook) models (6.5 mm width) | 6.5 mm | Low | No | HD2200, MyStyle 22, MyExcel 18/23 |
| F | Top-loading (Horizontal Rotary Hook) models (5 mm width) | 5 mm | Low | No | Sewist 625E, Jem Gold, Jem Gold2 |
| G | Front loading (Oscillating hook) models | 5 mm | Low | No | 3012/3016/3022, 1580LX, JR1012 |
| N | Embroidery & Sewing models with AcuFeed (9 mm) | 9 mm | High | Yes | HMC15000, HMC14000, SKYLINE S9 |
| O | Embroidery & Sewing models (9 mm width) | 9 mm | High | No | MC9900, MC9850 |
| P | Computer models with AcuFeed (9 mm width) | 9 mm | High | Yes | SKYLINE S7, SKYLINE S6, MC6700P |
| Q | Computer models (9 mm width) | 9 mm | High | No | SKYLINE S5, MC6650 |
Two cautions on this table. First, two Janome documents use two sets of width buckets: the US identification sheet offers 9 mm, 7 mm or 5 mm, while the global catalog also uses a 6.5 mm category. If your measured zig-zag lands near 6.5 mm, that is not an error — check the document that matches your market and model. Second, category D is the one row that spans two widths. Janome's own description reads "7 mm/5 mm" while the width column shows a single value of 7 mm. If you are in D, do not take 7 mm off this table. Look up your specific model's Maximum Stitch Width field, or run the zig-zag test.
The catalog also shows why "a zipper foot" is not one part. For its standard zipper foot Janome lists five part numbers. Three are snap-on: 808-852-003 for categories A, C, D, E and F; 940-290-000 for category G; 859-805-009 for categories N, O, P and Q. Two are screw-on: 200-334-002 for categories A and C, and 200-342-003 for D, E, F and G. Same function, five part numbers, sorted by exactly the properties above.
If you open that catalog yourself, read the rendered page rather than copying text out of the PDF. Janome prints all nine category letters in every row and colors the ones that do not apply white, so they are invisible on the page but still present in the file's text layer. Select-and-copy the 808-852-003 row and you get "ABCDEFGHI"; look at the page and it reads "A CDEF". H is overlockers and I is CoverPro, so the copied version would tell a coverstitch owner that a standard zipper foot fits. This page's figures above are taken from the rendered page.
Why the needle hits the foot
Stitch width is the check people skip, and it is the one that breaks hardware. Brother states the failure mode directly for its own machines: use the wrong foot for the stitch and "the needle may hit the presser foot, causing the needle to bend or break." That the specific cause is often a narrower needle opening — a foot built for a narrower maximum stitch width, fitted to a wider machine — is the inference, drawn from BERNINA coding maximum stitch width into its foot numbers and from Husqvarna Viking telling owners to hand-turn the wheel and adjust stitch width as needed.
BERNINA's lettering, from BERNINA of America's own At-A-Glance Reference Guide (©2009): a foot number with no letter "refers to a foot engineered to be used with BERNINA models that have a CB Hook and a maximum stitch width of 5.5mm." A "C" suffix "indicates a version of the foot made for models that have rotary hook systems and a maximum stitch width of 9mm," where C stands for coded and refers to a sensor that works with the machine's electronics to engage the wider stitch width. "D" marks feet for the 8-Series dual feed feature on models 830 and 820. Treat the letter as a strong signal rather than an absolute: BERNINA's own guide adds that unlettered feet "may also be compatible with models that have a 9mm width when a 9mm width is not applicable," naming pintuck feet #30, 31, 32 and 33, and lists two exceptions to the C rule — Overlock Foot #2/2A and Extra Wide Gathering Foot #16C are larger to fit wider feed dogs but carry no sensor. The guide also notes that a foot without a sensor is detected as a 5.5 mm foot. Separately, a sewing-parts retailer distinguishes BERNINA old-style feet (roughly 1954–1998, shank rounded at the back with no cut-out) from new-style feet (shank squared off with a notch at the top back); that shape distinction is retailer-stated, not in BERNINA's guide.
Dead ends and brand-specific traps
- Slant shank. A slant shank foot mounts only on a Singer slant-needle machine (Wikipedia; not a manufacturer specification). The reverse is not absolute, despite that source saying so. Sewing Parts Online documents a Singer proprietary slant shank adapter and notes that the low shank and slant shank versions "are sized differently," so a slant machine fitted with the correct slant adapter does take snap-on feet. What is out is a generic low-shank screw-on foot mounted directly. Check which adapter, if any, is on your machine before buying.
- Singer's own snap-on system. The same retailer reference describes proprietary Singer "skinny" adapters and feet, so called because the attachment bar is "just a little bit skinnier than the regular snap ons." Regular snap-on feet do not work with the skinny adapters and vice versa, and the skinny low-shank and slant-shank adapters are sized differently from each other.
- PFAFF and Husqvarna Viking. The retailer behind one widely sold "universal" snap-on range states that "some brands, most notably PFAFF, have a different snap-on system. Their snap on bar has a different length," and that some Husqvarna Viking owners have reported their snap-on feet do not fit. Those are seller caveats, not manufacturer positions.
- Husqvarna Viking publishes a lookup instead. Its accessory guide assigns most models to a machine group number, identified on page 5, and prints on each foot the group numbers it fits — groups 1 to 9. That is the field to read, not a generic shank label. The guide's own instruction adds that if your model is not included on that page, check husqvarnaviking.com; the 2024 edition will not carry machines released since.
- Brother publishes neither. Brother's Consumables & Options page for the XR9550 lists optional feet by part number — SA125/F001N quarter-inch piecing foot, SA140/F033N walking foot, SA187/F061 open toe quilting foot — and states no shank category anywhere on the page. So for a Brother the instruction is not "find your shank category." It is: open your own model's Brother support page, go to Consumables & Options, and buy the part number listed there for your machine. SINGER sits in between, stating that "Most modern SINGER sewing machines use standard low-shank snap-on presser feet," then telling you to check your manual or the product description "as some models may differ."
- Vintage Singers (inferred, and from a bobbin document). SINGER's bobbin support page treats the 221, 221K, 222, 301, Touch & Sew, older Futura and Centaur II as taking their own specific bobbins. SINGER publishes nothing equivalent for feet on these machines, and some of them — the 221 Featherweight among them — are ordinary low shank. Treat that bobbin list only as a prompt to confirm your own machine's foot system, not as evidence that generic feet will not fit.
The two-minute test before you sew
Once a foot is on, confirm clearance by hand. Husqvarna Viking publishes this step for its Edging Foot J: snap on the foot, then "Select an overcast or overedge stitch and turn the hand wheel by hand to be sure the needle does not hit the foot. Adjust stitch width as needed." That is the manufacturer's instruction, for that one foot. Untested extension, offered as common sense rather than from a source: do it unthreaded, at the widest stitch you actually intend to use with that foot, and turn through a full cycle so you see the needle clear the opening at both swing extremes before the motor ever runs.
Brother's caution on its own machines is blunt: "Only use presser feet designed specifically for this machine." Use of any other presser foot, it says, may result in injuries or damage to the machine. That is the manufacturer's position, and it is worth knowing you are departing from it when you fit a third-party foot. If a needle has struck a foot, replace it rather than sewing on — see the needle guide.
What to do next
Write four lines on a card and keep it with the machine: hook type, maximum stitch width in millimeters, shank height, and snap-on or screw-on. Janome's free one-page identification sheet walks you through the first three in the order above, and the method transfers to any brand. Then open your own maker's accessory document and read its fit line against the card. If your maker uses a category letter or a group number, find yours once and write that on the card too — it converts every future purchase into a single lookup. If your maker publishes neither, as Brother does not, write your model number on the card instead and buy from your model's own parts list.
Check it on your own equipment
These take you to the manufacturers and standards bodies the page draws on, so you can look up your exact model.

What this page does not tell you
- Nothing on this page was tested. No foot was fitted to any machine and nothing was measured. This is a compilation of published manufacturer documents, plus clearly labeled retailer and encyclopaedia references where no manufacturer source could be opened.
- The Janome zipper foot part numbers were read from the catalog page rendered at 600 dpi, not from the PDF's text layer. The text layer reports every category letter A-I for rows where the page shows only some, because Janome prints the non-applicable letters in white. Any figure copied out of that PDF as text should be checked against the rendered page.
- BERNINA's lettering claims now come from BERNINA of America's own At-A-Glance Reference Guide, retrieved from a dealer-hosted copy at media.rainpos.com because bernina.com returns HTTP 403 to automated fetching. That guide is dated 2009, so it describes the 8-Series era and will not cover models released since. The old-style versus new-style shank shapes are not in BERNINA's guide and remain a sewing-parts retailer's account.
- The shank measurements (0.5 in / 13 mm low, 1 in / 25 mm high) are encyclopaedia and retailer figures, not a manufacturer specification. The two sources describe slightly different measuring reference points - one from the bottom of the foot, one from the machine bed - while giving the same numbers. Treat them as approximate and compare against the foot already on your machine.
- The PFAFF and Husqvarna Viking exceptions to "universal", and the SINGER proprietary "skinny" adapter incompatibility, are stated by retailers - one of them selling universal feet - not confirmed by any manufacturer. Neither PFAFF's nor Husqvarna Viking's own position on third-party snap-on feet was located.
- The definition of "universal" here rests on one seller's stated fit line for one product. Other sellers may use the word differently. This page has not surveyed how the term is used across the market and cannot tell you what any other listing means by it.
- Janome's category table is reproduced as published and the model lists are partial extracts. Model ranges and category letters differ between markets, and Janome's US and global documents use different width buckets. Category D spans two widths in Janome's own description.
- This page cannot tell you whether a specific third-party foot will fit your specific machine. No cross-brand compatibility database was located, and none of the manufacturers cited publishes fit data for other makers' parts. It can only tell you which four values to establish and where each is written.
Sources
Manufacturers revise specifications. Every source below is dated — open it before you buy.
- Madam Sew's 32-piece 'Ultimate Presser Foot Set', sold as universal, states in its own listing that it 'Fits on low shank models of these brand machines' and that the contents are 'snap-on feet designed to fit most low-shank machines'.
- The same 'universal' listing publishes its own exceptions: the Pfaff Creative, the Husqvarna 300 and certain Janome models have 'not been a great match', and misaligned feet 'can risk needle breakage'.
- 'Universal' as used on presser foot listings means low-shank plus a snap-on ankle rather than every machine.
- A snap-on adapter replaces the machine's existing presser foot holder, after which feet clip on and off without tools; adapters are sold for high-shank machines and for BERNINA as well as low shank.
- Janome's presser foot identification guide asks three questions in this order: where the bobbin is inserted, what the maximum stitch width is, and shank height.
- Janome names two bobbin/hook arrangements on that sheet: horizontal rotary hook bobbin, and front-loading vertical oscillating hook.
- Dropping the bobbin in through a plate on the flat bed indicates a horizontal rotary hook; loading it through a front door into a case you lift out indicates a front-loading vertical oscillating hook.
- Janome's sheet gives three maximum stitch width options: 9 mm, 7 mm and 5 mm.
- Janome publishes a test for maximum stitch width: set the machine to its maximum stitch width, run a zig-zag stitch, then measure the resulting width. Janome also notes that many machines list the maximum stitch width and that it can be found on the Janome website.
- Janome states that shank height 'is only needed if you require a presser foot that attaches directly to the presser foot bar.'
- Janome states that all machines equipped with AcuFeed are high shank, and that the MC6650, MC9850 and Skyline S5 are high shank without the AcuFeed system.
- Attachment method is a fourth property a buyer must establish, separate from shank height, because a snap-on foot clips to an ankle rather than mounting on the presser bar.
- Janome's accessories catalog (Apr. 2026 edition) assigns models to lettered categories with published values for maximum zigzag width, shank height and AcuFeed: A (7 mm, High, No), C (7 mm, High, Yes), D (7 mm, Low, No), E (6.5 mm, Low, No), F (5 mm, Low, No), G (5 mm, Low, No), N (9 mm, High, Yes), O (9 mm, High, No), P (9 mm, High, Yes), Q (9 mm, High, No).
- Janome's catalog describes its sewing-machine categories as: A Embroidery & Sewing models (7 mm width) and SKYLINE S3; C Computer models with AcuFeed system (7 mm width) and MC6500P; D Computer models (7 mm/5 mm width); E Top-loading (Horizontal Rotary Hook) models (6.5 mm width); F Top-loading (Horizontal Rotary Hook) models (5 mm width); G Front loading (Oscillating hook) models; N Embroidery & Sewing models with AcuFeed (9 mm); O Embroidery & Sewing models (9 mm width); P Computer models with AcuFeed (9 mm width); Q Computer models (9 mm width).
- Janome's catalog lists example models per category, including SKYLINE S3, MC9000 and MC10000/10001 in A; HMC7700QCP, MC6600P and MC6500P in C; MC5200, MC4900QC and DC4030 in D; HD2200, MyStyle 22 and MyExcel 18/23 in E; Sewist 625E, Jem Gold and Jem Gold2 in F; 3012/3016/3022, 1580LX and JR1012 in G; HMC15000, HMC14000 and SKYLINE S9 in N; MC9900 and MC9850 in O; SKYLINE S7, SKYLINE S6 and MC6700P in P; SKYLINE S5 and MC6650 in Q.
- Janome's catalog covers non-zigzag and specialist machines under separate letters: B embroidery-only models; H overlockers; I CoverPro models; J high-speed straight-stitch models (1600P, HD9P, HD9 QCP); K needle punching model (FM725); L multi-needle models (MB-4, MB-4S, MB-7); M combined overlock and cover stitch models (1200D, 1100D).
- Janome leaves the Max. zigzag width, Shank and AcuFeed columns blank for categories B, H, I, J, K, L and M.
- Janome's global catalog independently corroborates the US sheet's high-shank exceptions: SKYLINE S5 and MC6650 appear in category Q (9 mm, High shank, no AcuFeed) and MC9850 appears in category O (9 mm, High shank, no AcuFeed).
- Janome's US identification sheet and its global catalog use different maximum-width buckets: the US sheet offers 9 mm, 7 mm and 5 mm, while the global catalog also uses a 6.5 mm category.
- Janome's category D is internally ambiguous in the source: its Features description reads 'Computer models (7 mm/5 mm width)' while its Max. zigzag width column gives a single value of 7 mm.
- Janome's catalog explains that high shank means the presser foot holder is installed at a higher position, low shank at a lower position, and that most sewing machines with embroidery features and/or the AcuFeed system have the high shank type of presser foot holder.
- For its standard zipper foot Janome lists five part numbers: three snap-on (808-852-003 for categories A, C, D, E and F; 940-290-000 for category G; 859-805-009 for categories N, O, P and Q) and two screw-on (200-334-002 for categories A and C; 200-342-003 for categories D, E, F and G).
- In the Janome catalog's fit tables, category letters that do not apply are printed in white, so they are invisible on the rendered page but still present in the PDF's text layer; copying the 808-852-003 row as text returns 'ABCDEFGHI' while the page shows 'A CDEF'.
- Janome's model specification pages name a field 'Maximum Stitch Width'; the MyStyle100 page gives 5mm, and the same specification list includes a separate 'Hook Type' field reading 'Top Loading Full Rotary Hook Bobbin'.
- Commonly published shank figures are low shank 0.5 inches (13 mm) and high shank 1 inch (25 mm), measured from the bottom of the foot to the center of the thumbscrew.
- A slant shank foot mounts only on a Singer slant-needle machine.
- One retailer's measuring method is to lower the presser foot and measure from the bed of the machine to the center of the thumbscrew, calling half an inch low shank and more than one inch high shank.
- A seller of 'universal' snap-on feet states that some brands, most notably PFAFF, have a different snap-on system whose snap-on bar has a different length, and that some Husqvarna Viking owners have reported their snap-on feet do not fit.
- BERNINA's own guide states that a foot number without a letter refers to a foot engineered for BERNINA models with a CB hook and a maximum stitch width of 5.5mm, and that a 'C' indicates a version for models with rotary hook systems and a maximum stitch width of 9mm, where C stands for coded and refers to a sensor that works with the machine's electronics to engage the wider stitch width.
- BERNINA's guide qualifies the no-letter rule: unlettered feet 'may also be compatible with models that have a 9mm width when a 9mm width is not applicable,' naming pintuck feet #30, 31, 32 and 33. It also lists exceptions to the C rule: Overlock Foot #2/2A and Extra Wide Gathering Foot #16C are larger to fit wider feed dogs but do not carry a sensor for a wider stitch width.
- BERNINA's guide states that feet numbered with a 'D' are designed to work with the 8-Series (models 830 and 820) Dual Feed feature, and that a foot without a sensor will be detected as a 5.5mm foot.
- A sewing-parts retailer distinguishes BERNINA old-style feet (roughly 1954-1998), whose shank has a rounded back with no cut-out, from new-style feet, whose shank is squared off with a notch cut out on the top back.
- Brother states that using the wrong presser foot for the stitch can cause a needle strike: 'Use the presser foot appropriate for the type of stitch that you wish to sew, otherwise the needle may hit the presser foot, causing the needle to bend or break.'
- A foot built for a narrower maximum stitch width has a narrower needle opening, so fitting it to a machine with a wider maximum stitch width can leave the needle striking the foot at full swing.
- Brother cautions that only presser feet designed specifically for the machine should be used, and that use of any other presser foot may result in injuries or damage to the machine.
- On the Brother HC1850 the presser foot is released by pressing a black button at the back of the presser foot holder, and a replacement foot's pin snaps into the shank as the presser foot lever is lowered.
- Brother publishes a per-model Consumables & Options list of optional presser feet with part numbers; for the XR9550/XR9550PRW it includes SA125/F001N 1/4 inch Piecing Foot, SA140/F033N Walking Foot and SA187/F061 Open Toe Quilting Foot. The page states no shank category anywhere.
- Brother's published answer to presser foot fit is per-model part numbers rather than a shank category, so the practical instruction for a Brother owner is to open their model's support page, go to Consumables & Options, and buy the part number listed there.
- Husqvarna Viking instructs owners, for its Edging Foot J, to snap on the foot, then 'Select an overcast or overedge stitch and turn the hand wheel by hand to be sure the needle does not hit the foot. Adjust stitch width as needed.'
- Husqvarna Viking groups its accessories by machine group number: page 5 lets an owner identify the group for their model from illustrations, each foot is printed with the group numbers it fits, and the guide uses groups 1 through 9.
- The Husqvarna Viking guide does not cover every model: page 5 states 'If your sewing machine model is not included below, visit our website www.husqvarnaviking.com for more information.'
- SINGER states that most modern SINGER sewing machines use standard low-shank snap-on presser feet, while advising owners to check the machine's manual or the presser foot's product description to confirm compatibility because some models may differ.
- A retailer reference states that SINGER made proprietary low shank and slant shank adapters, describes the proprietary parts as 'skinny' because the attachment bar is slightly narrower than regular snap-ons, and reports that the skinny low shank adapter and the skinny slant shank adapter are sized differently from each other.
- A Singer slant-needle machine fitted with the correct slant shank adapter can take snap-on feet, so the claim that such a machine accepts no other kind of foot is not absolute.
- SINGER's own support material treats models 221, 221K, 222 and 301, plus Touch & Sew, older Futura and Centaur II machines, as taking their own specific bobbins rather than a general-purpose one. SINGER publishes nothing equivalent for presser feet on those machines.
- Each major manufacturer publishes its own distinct scheme for encoding presser foot fit - Janome category letters, Husqvarna Viking machine group numbers, BERNINA letter suffixes, Brother per-model part number lists - rather than a shared cross-brand standard.
