How to Measure Your Foot Size at Home
Knowing your exact foot length (in cm) is the most accurate way to find your correct shoe size — especially when shopping online. This guide shows you the simple method professionals use.
What You’ll Need
- A sheet of paper
- A pencil
- A ruler or measuring tape (cm recommended)
- A wall
Step-by-Step: Measure Your Foot Length
1. Place paper against a wall
Put the paper flat on the floor with one edge touching the wall.
2. Stand on the paper
Stand with your heel lightly touching the wall. Distribute your weight evenly.
3. Mark the longest toe
Use the pencil to mark the tip of your longest toe (it’s not always the big toe).
4. Measure the distance
Measure from the edge of the paper (heel position) to the toe mark. Record this number in centimetres.
5. Measure both feet
Most people have one foot slightly larger. Always use the larger measurement.
How to Convert Foot Length to Shoe Size
Once you have your foot length in centimetres, you can compare it to standard shoe conversion tables:
Japan sizing is often shown directly in centimetres, while UK, US and EU sizes are calculated using regional sizing systems.
How to Measure Foot Width
If you regularly experience tightness on the sides of your shoes, measure width as well.
- Wrap a measuring tape around the widest part of your foot.
- Do this while standing.
- Compare with brand width charts where available.

Common Questions
Should I measure in the morning or evening?
Measure in the evening. Feet naturally swell slightly throughout the day, so evening measurements are more realistic.
How much space should there be in a shoe?
Ideally, allow about 5–10mm between your longest toe and the end of the shoe.
Why does my size vary between brands?
Brands use different shoe lasts and fit profiles. Always treat size charts as guides rather than exact guarantees.
