How to Measure Your Shoe Size at Home
All you need is a sheet of paper, a pen, and a ruler. Measure your foot length, then convert it to any system with the tool below.
- Tape paper to the floor against a wall (hard floor, not carpet).
- Stand with your heel to the wall, weight on the foot so it spreads naturally.
- Mark your longest toe. It isn't always the big toe — mark whichever reaches furthest.
- Measure wall-to-mark in centimeters. That's your foot length.
- Repeat for the other foot and use the larger measurement.
Enter a foot length above to see your size in US, UK, EU, and cm.
Tips for an accurate measurement
- Measure in the afternoon — feet swell through the day.
- Wear the socks you'll pair with the shoes.
- Keep the ruler straight and read to the nearest millimeter — 2 mm is about a third of a size.
- For width, trace the whole foot outline and compare the ball width to a brand's width guide.

Frequently asked questions
What time of day should I measure my feet?
Late afternoon or evening. Feet swell over the day and after activity, so a morning measurement can leave you with shoes that pinch by dinnertime. Measure at the end of a normal day for the most livable fit.
Should I measure barefoot or with socks?
Wear the socks you'll actually wear with the shoes — thin dress socks for dress shoes, thicker athletic socks for trainers. The sock adds a few millimeters, and matching it makes the size truer.
Do I need to add anything to my measured length?
The size charts already build in toe room, so match your bare measured length to the chart — don't pre-add wiggle room or you'll size up twice. For running shoes specifically, many people still go up a half size for downhill toe clearance.
My two feet are different sizes — which do I use?
Almost everyone has one foot slightly larger. Always fit to the larger foot; a thin insole or heel grip can take up the small extra room in the other shoe.
