A square embroidery hoop is one of those tools you do not know you want until you see a sampler sitting properly inside one. The corners are generously rounded, the frame is a slim moulded plastic in a single soft colour, and the whole thing looks less like equipment than like the frame the piece will end up in. Lift it and it weighs almost nothing; press the rings together and a deep inner lip closes on the fabric and keeps it there.
That shape is the entire point. A round hoop crops a square design, and grid-based work — samplers, monograms, lettering, blackwork, anything charted — fights the curve the whole way. Here the border of the design and the border of the hoop are the same shape, so you stop re-hooping to reach a corner.
Five sizes, from a 7 × 7.5 cm that sits in the palm to a 25 × 28 cm big enough for a full alphabet. Take one, or take all five.
(Round and rectangular hoops are on this page too — select the shape under Style options, no need to go looking.)

| Size | Metric | Imperial | Best for |
|---|---|---|---|
| Square 1 | 7 × 7.5 cm | 2.8 × 3.0 in | Initials, tiny motifs, ornaments |
| Square 2 | 9.5 × 11 cm | 3.7 × 4.3 in | Single monograms, small charted motifs |
| Square 3 | 14 × 16.5 cm | 5.5 × 6.5 in | The everyday size — most charted patterns |
| Square 4 | 22 × 19.5 cm | 8.6 × 7.7 in | Landscape-oriented designs — wider than tall |
| Square 5 | 25 × 28 cm | 9.8 × 11.0 in | Full samplers, alphabets, large blackwork |
Square 4 is the odd one: at 22 × 19.5 cm it is wider than it is tall, where the other four are taller than wide. If your chart is landscape, that is the one you want.

This is the one thing worth understanding before buying any square hoop. A true sharp-cornered frame concentrates tension at the four corners and lets it go slack along the straight runs — which is the standard, and fair, objection to square hoops.
These are moulded with a generous radius at every corner. The fabric turns the corner rather than folding over it, so tension carries round the frame instead of pooling in four points. It is the difference between a square hoop that holds and one that you spend the evening re-tightening.

Against a round hoop. A circle gives marginally more even tension on plain fabric, and for a round motif it is the right tool. For anything charted or square, it wastes the corners and forces re-hooping. Most stitchers end up owning both and reaching for whichever matches the design.
Against a Q-snap or scroll frame. Those give a larger rectangular working area and suit very long bands. They are also bulkier, slower to set up, and not something the finished piece stays in. A square hoop sets up in seconds and doubles as the frame.
Against a wooden square hoop. Wood looks warmer on a wall. Plastic holds stiff aida better, because the moulded lip gives the frames something to grip, and it will not split at a corner joint — which is where wooden square hoops fail.

Moulded plastic frame with a metal tension screw. Wipe clean with a damp cloth. It will not rust, will not stain white linen or aida, and does not mind a humid room. The frame flexes rather than snapping, so it survives a project bag.
Are square embroidery hoops good?
For square and grid-based designs, yes — they hold the design the shape it was charted and save you re-hooping to reach a corner. The fair criticism of square hoops is corner tension, and the rounded corners here are the answer to it. For a round motif on plain fabric, a round hoop is still the better tool.
Can you get square embroidery hoops?
Yes, though they are much harder to find than round ones, which is why most stitchers have never owned one. These come in five sizes from 7 × 7.5 cm to 25 × 28 cm.
Are there rectangular embroidery hoops?
Yes. We stock a rectangular range in five sizes up to 27 × 39 cm, for lettering, quotes and landscape scenes.
Is a plastic or wooden embroidery hoop better?
For holding tension on aida, plastic generally wins — the moulded lip grips where a smooth wooden surface lets stiff fabric creep. Wood wins on appearance if the hoop is staying on the wall. For a square hoop specifically, plastic has one extra advantage: there are no corner joints to split.
Are these magnetic?
No. They close with a hand-tightened screw. No magnet near a computerised machine, and no trouble with fine needles that magnets grip poorly.
Will these fit an embroidery machine?
No. These are hand-embroidery hoops. Machine hoops are made to a specific bracket for a specific machine.
Do the colours arrive as shown?
Yes — one shade per size, as photographed.
Square designs deserve a square hoop.
