Your favourite shirt knows your size.

Give us one garment you already love wearing. We'll work out its real measurements and tell you what to order anywhere else.

Shoot from aboveWhole garment in frame, camera straight overhead.

A plain floor or table works best. Avoid hard shadows falling across the garment.

The bank card is the ruler. It is a known size, so everything else is measured from it. This is the part worth getting right.

Beside the garment, flat on the surface — not on the fabric, not on a fold or a seam, and out of any hard shadow. Any plain bank card will do.

Free, no account needed. Early beta — measurements read a few centimetres under while we calibrate, so double-check anything expensive.

Here's what you get

A real scan of a real t-shirt. Yours takes about a minute.

Laid flat, bank card beside it, photographed from above. The card is always 85.6 mm wide — that's how it knows the scale.

What it measured

Chest (pit to pit) 51.1 cm

Length (shoulder–hem) 56.2 cm

Shoulder 53.6 cm

Sleeve 17.5 cm

Hem width 53.6 cm

Then compare it to any shop

Scan a garment

No tape measure needed — a bank card is the ruler.

Take the photo

Smooth it flat — don't stretch it. Pat the wrinkles out, but let the fabric relax; pulling it taut adds width. Sleeves down beside the body, not out to the sides.
Card on the surface, not the fabric. Away from folds, seams and hard shadow.
Shoot from straight above. Whole garment and the card in frame.

Tips for a good scan

Use a contrasting surface — a grey top on grey carpet can't be measured. A bed sheet or towel in a different colour works well.
Boxy tees — if the sleeves won't sit down by the sides, fold them back over the front so the outline is just the body.
Stretchy fabric — a soft jersey tee can read a couple of cm wider or narrower depending on how much it's pulled. Lay it the same relaxed way each time, and don't stretch it flat.
Trousers and jeans — lay them out normally, legs apart. No folding needed.

Strongly recommended. Take a second photo of the garment exactly as it is — don't move it, just photograph it again. We measure that one too and compare. Two photos of the same garment can differ by several centimetres, so if they disagree, the scan isn't reliable and we'll tell you. (A photo of the back, laid out the same way, works too.)
