Embroidery machine hoop types: standard, magnetic, cap and more

Embroidery machine hoops come in a few types: standard two-ring hoops, magnetic hoops, multi-position or border frames, and cap frames. Each type changes how the fabric is held, but none can stitch beyond your machine's embroidery field, and each one must be listed for your exact model. Standard hoops come with the machine, while the others are add-ons, and sock hoops are not part of the maker hoop lists we checked.

An embroidery hoop holds fabric and stabilizer flat while the needle stitches. The main types are standard two-ring hoops, magnetic hoops, multi-position and border frames, and cap frames. What decides the size of your design is not the hoop type but your machine’s embroidery field, the largest area it can stitch in one hooping. Every hoop also has to be made for your machine’s carriage.

Brother, Baby Lock, Singer, OESD and HoopMaster’s Mighty Hoop are named below as examples. This site is not affiliated with any of them.

Standard hoops

A standard hoop is two rings. The fabric and stabilizer sit between them and the inner ring locks the layers in place. Madeira’s hooping guide says to set the tension screw on the bottom hoop before you hoop, to hold the fabric firmly without stretching it, and to use the smallest hoop that fits the design, because a smaller hoop lets the fabric move less.

The size on the label is not always the stitch area. Kimberbell points out that a 4 × 4 in hoop stitches about 3.94 × 3.94 in (100 × 100 mm), because the needle and presser foot need a margin near the inner edge. Sweet Pea warns that a true 6 × 10 in hoop is 160 × 260 mm (about 6.3 × 10.2 in), while some hoops sold under that name are only 150 × 240 mm and cannot stitch a full-size design. Check the millimeter size in your manual, and see our hoop sizes overview for the common ones.

The usual weak spots are hoop marks on delicate fabrics and thick items that will not close in the rings. Our hooping guide covers floating and other fixes.

Magnetic hoops

A magnetic hoop clamps the fabric with magnets over a metal base frame instead of squeezing it between rings. It is quick to load and suits thick or bulky items. Brother’s 4 × 4 in magnetic hoop (SAMFM100), for example, is listed for the SE600, SE700 and PE535 among other models, and is rated for material up to 2 mm thick.

Fit is model-specific. OESD’s 5 × 7 in Snap Hoop Monster lists the Brother and Baby Lock machines it works with, and HoopMaster sells Mighty Hoop versions split by brand and by single-needle, 6-needle and 10-needle machines. One sewing education page notes that some large third-party magnetic hoops do not grip as tightly as Brother’s own, so stretchy fabric with a dense design may shift. Read the magnetic hoops guide for how they work and for magnet safety.

Multi-position and border hoops

A multi-position hoop is a long frame with several attach positions. You stitch one section, move the frame to the next position and stitch again, so you can build a long design without re-hooping the fabric. Brother’s SA445 is a 5 × 12 in hoop with three pegs for moving the frame in sections. Brother’s page lists models including the PE700II, PE770 and NS1150E, so check that yours is on the list.

It does not make the machine’s field bigger. Sweet Pea and Embroidery Library both say the machine’s maximum embroidery area still applies, so a 5 × 7 in machine with a 5 × 12 in frame stitches 5 × 7 in per position. Some 4 × 4 in Brother models list a frame of about 4 × 6.7 in with two attach positions, and each design there is still limited to 4 × 4 in. Your design has to be split to match the positions. See the 5 × 12 in hoop page for details.

Border and endless hoops are built for repeats along an edge. Singer’s endless hoop is 7 × 4 in (180 × 100 mm). It is model-specific, so check Singer’s compatibility list for your machine. Its inner and outer rings are hinged. You lift the inner ring with a lever, slide the fabric to the next repeat and lower it again. The designs include temporary L-shaped stitches at the corners that show where to line up the next repeat. Baby Lock and Brother also list border frames of about 4 × 7 in for some models.

Cap frames

A cap frame is the hoop type built for the curved front of a finished cap. Brother’s PRCF3 and Baby Lock’s EPCF3 both stitch an area of 130 × 60 mm, about 5 × 2.4 in. Each set includes a frame, a driver that replaces the normal frame holder on the carriage, and a mounting jig for loading the cap.

Fit is narrow. Brother’s PRCF3 page names the PR1000e, PR680W and PRS100, among other PR-series models. Baby Lock lists the Alliance, Array, Capella, Endurance 2, Intrepid, Valiant and Venture for the EPCF3. Brother also sells a flat brim frame (PRCF5) and a wide frame (PRPCF1) with a 14 × 2-3/8 in area, described as reaching almost ear to ear. Both are listed for a short set of Brother PR-line machines only.

Baby Lock’s manual also sets limits on caps:

It does not recommend caps with a front panel less than 2 in (50 mm) high, such as a sun visor.
It does not recommend caps with a brim longer than about 3 in (80 mm).
It advises against stretch fabric, polyester foam, melton wool, 100% nylon and suede, because they are hard to frame and may wrinkle or shrink.
It says the frame has no centerline guide for placing the cap, so you mark one yourself with chalk.

On a machine with no cap frame, OESD suggests hooping sticky stabilizer instead of the cap and pressing the flat part of a soft cap onto it. The usable area is small, roughly 3.5 × 2.5 in on its sample cap. Our hat guide covers this, and the hat machines list shows which models take a cap frame, including single-needle ones such as the Brother PRS100.

Sock hoops and other specialty hoops

“Sock hoop” is a common search, but it is not a hoop type that the makers list. We did not find one in the Brother, Baby Lock, Janome or Singer hoop lists for the machines on this site. If you find a sock hoop from another seller, treat it as an aftermarket hoop: confirm it is listed for your model, and stitch a sample on scrap before you use a real sock.

A sock is a tube, so make sure only the layer you are stitching sits under the needle and the other layer is pulled clear. Without a special hoop, the usual approach for awkward items is to hoop stabilizer and float the item on top with temporary spray adhesive or stick-on backing, as Madeira suggests for hard-to-hoop materials.

How to check that a hoop fits your machine

Find your field. Look in your manual for the maximum embroidery size, in millimeters.
Use the maker’s list. Brother and Baby Lock list compatible models on each accessory’s page. Baby Lock’s 9½ × 14 in IQ Intuition hoop (240 × 360 mm) is listed for the Altair, Altair 2, Meridian and Meridian 2 and has a coded feature that Baby Lock’s positioning app reads.
Check your software version. Brother’s SA441 page recommends updating some older models to version 2.02 or later so they do not stitch outside the hoop’s area, and Baby Lock’s cap frame manual says to update your machine first.
Compare in millimeters. Compare the hoop’s stitch area with your design, not just the label.
Preview before stitching. Trace the design outline on the machine to confirm the needle will not strike the frame.

The will-it-fit tool compares a design with a machine’s field.

Aftermarket hoops

Third-party hoops can fill gaps when a maker does not sell your size or type. One sewing education page cautions that not all hoops are of the same quality and not all machines work with all hoops, and it points buyers to a brand’s compatibility chart or to the maker.

Buy only from a seller that lists your exact model, and keep your standard hoops as a backup. A hoop that attaches but is the wrong size for your field is the riskiest case, so always trace the design before stitching.

Frequently asked questions

What size embroidery hoop do I need for my machine?

Use the largest hoop your maker lists for your exact model, but only stitch designs that fit the machine's embroidery field, such as 4 × 4 in (100 × 100 mm) or 5 × 7 in (130 × 180 mm). For a small design, a smaller hoop holds the fabric more steadily.

Can I use any embroidery hoop on my machine?

No. A hoop must attach to your machine's carriage and be listed for your model, and some need a software update first. A hoop that is bigger than the field does not enlarge it.

What is a multi-position embroidery hoop?

It is a long frame with several attach positions. You stitch one section, move the frame, and stitch the next without re-hooping the fabric. Each section is still limited to your machine's field, so a 5 × 7 in machine with a 5 × 12 in frame stitches 5 × 7 in at a time.

Is there a hat hoop for a home embroidery machine?

Only on some models. Brother and Baby Lock sell cap frames that hold the curved front of a cap and mount on a cap frame driver. They stitch an area of about 5 × 2.4 in (130 × 60 mm), and the makers list the models each frame fits.

Is there a sock hoop for embroidery machines?

We did not find one in the Brother, Baby Lock, Janome or Singer hoop lists for the machines on this site. If you find a sock hoop from another seller, treat it as an aftermarket hoop: check that it is listed for your model and stitch a sample on scrap first.
