A hoop size is the largest design a machine can stitch in one hooping. 4x4 inches (100x100 mm) suits monograms and patches; 5x7 (130x180 mm) fits shirt chests, tote fronts and most quilt blocks; 6x10 (160x260 mm) and 8x12 (200x300 mm) handle jacket backs and big quilt designs. Your machine sets the maximum, so choose the machine by the hoop you need.

Hoop size vs embroidery field
Two terms get mixed up:
- Embroidery field (or area) is the machine's limit: the farthest the arm can move the hoop. The SE700's is 4x4; the PE900's is 5x7.
- Hoop size is the stitching area inside a particular hoop. It can be smaller than the field, never larger in a single position.
That's why a 4x4 machine can't use a 5x7 hoop, but a 5x7 machine can use a 4x4 hoop. Using the smallest hoop that fits your design holds the fabric tighter and saves stabilizer.
Multi-position hoops
Multi-position hoops are longer than the machine's field and attach to the arm in two or three positions. You stitch one section, move the hoop to the next position, and continue. The 4x6.75-inch hoop (SA434) does this for 4x4 machines and lists the SE700, SE600, PE545 and PE535 as compatible; the 5x12 hoop in the Sew Tech 4-hoop set does it for 5x7 machines like the PE900 and SE2000. You need designs split (or splittable) for the positions.
Brother hoop codes, decoded
Brother and compatible hoops are identified by SA numbers (and Baby Lock EF numbers). The codes below appear on Brother-compatible hoop listings on Amazon:
| Code | Size | Typical machines |
|---|---|---|
| SA431 (EF61) | Small, about 1 x 2.5" | 4x4 SE/PE machines |
| SA432 (EF62) | 4 x 4" | 4x4 SE/PE machines (SE700, SE600, PE545, PE535) |
| SA434 (EF71) | 4 x 6.75" multi-position | 4x4 SE/PE machines |
| SA442 to SA445 (EF82 to EF85) | Pocket, 4x4, 5x7, 5x12 | 5x7 machines (PE900, PE800, SE2000, SE1900) |
| SA444 | 5 x 7" (130 x 180 mm) | 5x7 machines |
| SA441 (EF81) | 6 x 10" (160 x 260 mm) | Larger Innov-is and Baby Lock machines |
| SA447 (EF92) | 8 x 12" (200 x 300 mm) | Larger Innov-is and Baby Lock machines |
Always check the compatibility list on the specific listing: the same size can come in different attachments for different machine families.

Hooping tips that apply to every size
- Mark the center with a fabric pen and use the hoop's grid template to line it up.
- Taut, not stretched. Fabric should be smooth like a drum, but stretching it (especially knits) makes the design pucker when it relaxes.
- Use the smallest hoop that fits the design.
- Float thick items: hoop just the stabilizer and pin or spray-baste the item on top when it won't fit in the hoop.
- Pick the right stabilizer. See our stabilizer guide.
Hand embroidery hoops are measured differently
If you searched for hoop sizes for hand embroidery, those hoops are round (or oval) and sized by inner diameter, typically from about 3 inches up to 12 inches or more. They don't attach to a machine, and their size is about how much fabric you hold taut at once, not a stitching limit. A 6-piece round hoop set (3.6 to 10.7 inches) was among the best-selling hoop listings in our Amazon search. As a rule of thumb, pick a hand hoop a little larger than the design so the ring doesn't crush finished stitches. Machine hoops, by contrast, must match your machine's attachment and field.
Which size should your machine have?
If you're buying a machine, decide the hoop size before anything else: it's the one spec you can't upgrade. Choose 4x4 for monograms and small gifts, 5x7 for clothing and bags, and 6x10 or larger for jacket backs and big quilting designs. Our beginner embroidery machine guide and PE line comparison show the machines at each size.
