A hoop size is the largest design a machine can stitch in one hooping. Monograms and patches fit in 4x4 inches (100x100 mm). A 5x7 (130x180 mm) takes shirt chests and tote fronts, plus most quilt blocks. Jacket backs and big quilt designs need 6x10 (160x260 mm) or 8x12 (200x300 mm). The machine sets the maximum, so pick the machine by the hoop you need.

Hoop size vs embroidery field
Two terms get mixed up. The embroidery field (or area) is the machine's limit, the farthest the arm can move the hoop: 4x4 on the SE700, 5x7 on the PE900. The hoop size is the stitching area inside one particular hoop. It can be smaller than the field, but never larger in a single position.
So a 4x4 machine can't use a 5x7 hoop, while a 5x7 machine can use a 4x4 one. In fact you should: the smallest hoop that fits your design holds the fabric tighter and uses less stabilizer.
Multi-position hoops
A multi-position hoop is longer than the machine's field and clips onto the arm in two or three positions. Stitch one section, move the hoop to the next position, carry on. For 4x4 machines the 4x6.75-inch hoop (SA434) does this, and it lists the SE700, SE600, PE545 and PE535 as compatible. For 5x7 machines like the PE900 and SE2000, the 5x12 hoop in the Sew Tech 4-hoop set does the same. Either way, the design has to be split (or splittable) for the positions.
Brother hoop codes, decoded
Brother hoops and their compatibles go by SA numbers; Baby Lock uses EF numbers. These codes 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 |
Check the compatibility list on the specific listing every time. The same size can come with different attachments for different machine families.

Hooping tips that apply to every size
Mark the center with a fabric pen and line it up using the hoop's grid template. Then hoop the fabric taut but not stretched. It should be smooth like a drum, but stretched fabric (knits especially) relaxes after stitching and the design puckers.
Use the smallest hoop that fits the design. When an item is too thick to hoop at all, float it: hoop just the stabilizer, then pin or spray-baste the item on top. And match the stabilizer to the fabric; our stabilizer guide covers which goes where.
Hand embroidery hoops are measured differently
Hand embroidery hoops are round (or oval) and sized by inner diameter, usually 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. Choose a hand hoop a little larger than the design so the ring doesn't crush finished stitches. Machine hoops are the opposite case: they have to match your machine's attachment and field.
Which size should your machine have?
Settle the hoop size before you compare anything else, because it's the one spec you can't upgrade later. Monograms and small gifts only? 4x4 is enough. Clothing and bags need 5x7. Jacket backs and big quilting designs mean 6x10 or larger, and a bigger budget. Our beginner embroidery machine guide and PE line comparison show the machines at each size.
