01 — Sneakers, slides & sandals
Foot length

- 3.Measure wall to mark in centimetres. Do both feet; use the longer one.
Guide · 2 minutes · a tape or a ruler
Three numbers.
That's the whole system.
Everything on Fit Check is anchored to one body measurement per category. You don't have to measure — a size you already wear works too — but a measurement is the most precise anchor there is.
02 — T-shirts & tops
Chest
- 1.Arms relaxed at your sides, breathing normally.
- 2.Wrap the tape around the fullest part of your chest, under the armpits.
- 3.Keep it level across your back and snug, not tight.
03 — Trousers & jeans
Waist
- 1.Find your natural waist — where your trousers actually sit.
- 2.Wrap the tape around it, one finger's width of slack.
- 3.Read the number where the tape meets its zero end.
Good to know
- Measure late in the day
- Feet swell a little by evening — that's the size your shoes need to fit.
- Wear what you'd wear
- Socks for sneakers, a thin tee for chest. Not a jacket.
- Round to the half
- Half a centimetre is the step most footwear charts use.
- Between two sizes?
- Every brand page shows the gap in cm, so you can see which way you lean.
