Measure your foot
Buying shoes online and unsure of your exact size? Put your foot on a plain A4 sheet, photograph it from above, and the tool finds the sheet, straightens it and measures your foot in millimetres — then gives EU, UK and US sizes for men, women and kids. The photo never leaves your device.

Standard sizes with 10 mm of room; brand charts vary a little.
How to use it
- Put an A4 sheet on the floor against a wall, stand with your heel on the wall and your foot on the sheet.
- Photograph straight from above with the whole sheet in view. The tool finds and straightens the sheet.
- Check the heel and longest-toe points (drag them if needed) and read the length and sizes.
Questions
Why A4?
Its size is known everywhere (210 × 297 mm), so it becomes the ruler that converts pixels into millimetres. Any white A4 sheet will do.
How accurate?
±2 mm when the whole sheet is in the photo and the shot is straight from above. Measure both feet — one is often bigger — and go by the larger.
Sizes differ between brands?
Yes; our table gives the standard size from foot length with 10 mm of room. If a brand publishes its own millimetre chart, use the foot length measured here directly.
For kids?
Same method, and they need it most since feet grow every couple of months. Measure standing.
