4 × 4 vs 5 × 7 embroidery hoop: what fits and which to buy

Hoop size is the single most important choice when you buy a first embroidery machine, because it is the one you cannot change later. The names “4 × 4” and “5 × 7” sound simple, but they are rounded inch labels for millimeter limits, and the gap between them is bigger than the numbers suggest.

This guide uses Brother’s published field sizes and manuals (checked October 7, 2026) to show exactly what fits, where the traps are, and how to choose. EmbroideryWise is research-based; the sizes and limits below are attributed to their sources.

The real limits, in millimeters

	4 × 4 class	5 × 7 class
Brother’s stated field	100 × 100 mm	130 × 180 mm (manual: 180 × 130 mm)
In inches	3.94 × 3.94 in	5.12 × 7.09 in
Area	10,000 mm²	23,400 mm²
Relative area	1×	2.34×
Brother machines (current)	PE545, SE630, SE700, PP1	PE900, SE2000
Brother machines (discontinued)	PE535	PE800, SE1900

The field is the area the machine’s embroidery arm can move the needle through. It is the real limit. The plastic hoop is slightly bigger than the field so it can hold fabric around the edges, which is why a hoop’s outer size tells you little.

The 101.6 mm trap

Four inches is 101.6 mm. Brother’s 4 × 4 field is 100 mm. So a design that is exactly 4.00 inches wide is 1.6 mm too wide for the field.

Most design shops size their “4 × 4” files to fit under 100 mm, but not every free or hand-made file does. Always read the stitched size in millimeters, or check it with the hoop fit checker, before you buy or load a design.

The 5 × 7 label works the other way. Five by seven inches is 127 × 177.8 mm, slightly smaller than Brother’s 130 × 180 mm field, so a design at exactly 5 × 7 inches fits with a little room to spare.

Area math: why 5 × 7 is more than “a bit bigger”

The labels make it sound like 5 × 7 is one or three inches bigger. In area, it is 2.34 times the size: 23,400 mm² versus 10,000 mm².

That extra area is mostly height. A 5 × 7 field is 30 mm wider and 80 mm taller. Designs that are long or tall, like a name across a towel, a vertical motif on a tote or a crest on a shirt front, are exactly the ones that do not fit a 4 × 4.

Rotation: when turning a design helps

On a 5 × 7 field, rotating a design 90° can make it fit:

• 170 × 120 mm design: too wide upright (170 > 130), but rotated it becomes 120 × 170 mm and fits.
• 140 × 190 mm design: too big both ways. Rotated it is 190 × 140, still too wide. It needs a bigger machine or a split.
• 150 × 60 mm name: rotated to 60 × 150 mm, it fits; you hoop the item sideways.

On a 4 × 4 field, a 90° turn never helps, because the field is square. If a design does not fit at 100 × 100 mm one way, it does not fit turned sideways either. Tilting a long, thin design at an angle can sometimes squeeze it in, but that changes how it sits on the item, so it is rarely what you want.

The hoop fit checker tests both orientations for you.

What fits in each hoop

Project	4 × 4 (100 × 100 mm)	5 × 7 (130 × 180 mm)	Notes
Monogram or initials	Yes	Yes	The classic 4 × 4 job
Left-chest logo	Yes	Yes	Printful caps left-chest embroidery at 4 × 4 in; watch the 101.6 mm trap
Small baby onesie motif	Usually	Yes	Small garments limit hooping space more than the field does
Patch or small appliqué	Yes, under about 95 mm	Yes	Leave a margin for the satin edge
Name across a hand towel, about 150 mm	No	Yes, rotated	Hoop the towel sideways
Tote bag design, about 120 × 160 mm	No	Yes	5 × 7 is the common tote size
Adult T-shirt front	Small designs only	Yes, up to 130 × 180 mm	Many front designs are sold in 5 × 7 sizes
Larger front, like Printful’s 10 × 6 in embroidery area	No	No	Needs a 6 × 10 field (160 × 260 mm)
Jacket back	No	No	Usually larger than 6 × 10 as well

Bigger accessory hoops do not expand the field

This is one of the most expensive misunderstandings. If you buy a larger hoop for a 4 × 4 machine, even one that physically clips on, the machine’s arm still only moves within 100 × 100 mm. The extra hoop area is unused.

Hoops sold as accessories serve other purposes: different shapes, easier hooping, magnetic clamping. Brother, for example, says the PE900 and SE2000 work with an optional 4 × 7 inch magnetic frame. That frame is smaller than the 5 × 7 field, not larger. Nothing you attach changes the machine’s maximum.

Going the other way is fine. A 5 × 7 machine stitches any 4 × 4 design. Madeira recommends using the smallest hoop available for the design, because a snug hoop holds fabric more securely, so a smaller compatible hoop is useful when you have one.

Multi-position and split designs

If a design is too large for your field, there are two workarounds:

• Split designs: some designs are sold as several files, each sized for a smaller hoop, with alignment stitches or marks so you can re-hoop and stitch the next section. It works for borders, quilt panels and large pieces, but each section adds hooping and alignment work.
• Multi-position hoops: some machines accept hoops that attach in more than one position, so you can stitch one section, move the hoop to the next position and continue. Each section must still fit within the machine’s field; a multi-position hoop does not let a single, unsplit design exceed it.

Either way, a single design larger than your field must be split. If you find yourself doing this often, that is the signal you bought the smaller field.

Shrinking designs to fit

You can reduce a design slightly in software. Embrilliance Essentials, for example, resizes with stitch recalculation, which adjusts the stitches rather than just squeezing them. Large reductions still crowd detail, especially small lettering, so start with a design digitized near your target size. Our design resizing guide covers safe limits.

Stitch-count limits (and Brother’s conflicting figures)

Size is not the only limit. Brother’s support article on designs the machine will not recognize says one reason is that “the total number of stitches per pattern exceeds the maximum stitch count for the hoop.” It lists:

Hoop	Brother support article	Brother operation manuals
4 × 4	30,000 stitches	Up to 100,000 (PE545, SE700)
5 × 7	50,000 stitches	Up to 200,000 (PE900, SE2000)

These figures conflict, and Brother does not explain the difference. Most designs that fit these fields are far below even the lower figures. If a dense design refuses to load, check its stitch count against your own manual, and see embroidery machine not reading PES files for other causes.

Which should you buy?

If you…	Choose
Only plan monograms, names, small logos and patches	4 × 4
Want T-shirt fronts, totes or popular design-shop sizes	5 × 7
Are not sure yet	5 × 7 (a 5 × 7 machine still does everything a 4 × 4 does)
Already own 5 × 7 designs you love	5 × 7
Know you want 10 × 6 in fronts or large quilt blocks	6 × 10; see PE900 vs NQ1700E

Choose 4 × 4 if…

Every project you can picture is under about 95 mm on each side, and you are buying mainly for monogramming or small motifs. Brother’s current 4 × 4 options are the embroidery-only PE545 and the SE700 and SE630 combos.

Choose 5 × 7 if…

You can name even one project bigger than 4 × 4. If you outgrow a 4 × 4 field, the only fix is another machine. In Brother’s current line, that means the PE900 (embroidery-only) or SE2000 (combo); see PE900 vs SE2000 and SE700 vs SE2000.

The bottom line

Read sizes in millimeters, not labels. A 4 × 4 field is 100 × 100 mm and a 5 × 7 field is 130 × 180 mm, with 2.34 times the area. A 90° turn can help on 5 × 7 but never on 4 × 4, and accessory hoops never expand a machine’s field.
