How to measure your feet

Numbers on a box vary by brand, but your foot length doesn't. Measure once and you can shop in any system with confidence.

1

Stand on paper

Put a sheet of paper on a hard floor against a wall. Stand with your heel touching the wall, full weight on the foot.

2

Mark the longest toe

Mark the paper at the tip of your longest toe — which isn't always the big toe.

3

Measure heel to toe

Measure the distance from the wall edge to your mark in centimetres. That's your foot length.

4

Use the larger foot

Measure both feet and go by the bigger one. Measure in the evening, when feet are at their largest.

A note on accuracy: these conversions are widely used industry standards, but sizing is not governed by a single global rule. Brands build shoes on different lasts, so a size that fits in one make can run half a size out in another. Treat this guide as your starting point, then check the brand's own chart and, where you can, the foot-length (cm) figure on the box.
