What this tool does
- Convert your foot length to EU, UK and US sizes before ordering overseas, so you do not order half a size too small.
- Buying for kids: measure in millimetres, convert, then decide whether to size up for the 5–10 mm of growing room.
- Check a product page: reverse the advertised EU size into a foot length and see whether it matches yours.
- For shoe shops and support desks, answer 'I measure 26 cm, what size do I wear' with one consistent formula.

26
Output
脚长：260 mm（26 cm / 10.24 英寸） 中国码：42（≈ 脚长 × 2 − 10） 欧洲码 EU：41（≈ 脚长 × 1.5 + 2，Paris point） 英国码 UK：7.7（男码 ≈ 脚长英寸 × 3 − 23） 美国码 US：8.7（男码 ≈ 脚长英寸 × 3 − 22） 日本码 JP：26（等于脚长 cm） 说明：以上为通用近似式，同脚长在不同楦型下可能差半码；买鞋以脚长为准，并预留 5–10 mm 活动量。
Chinese size ≈ foot length (cm) × 2 − 10; EU ≈ foot length (cm) × 1.5 + 2; UK/US use inches.
Frequently asked questions
Why use foot length instead of an old shoe size?
Old sizes are labelled inconsistently between brands, while foot length in millimetres is a physical measurement you can take. The Chinese standard GB/T 3293 uses millimetre foot length as the size number, so the tool shows both mm and cm for a reliable conversion.
What formula gives Chinese size 42?
Chinese size ≈ foot length (cm) × 2 − 10. A 26 cm foot gives 26 × 2 − 10 = 42, which is the same as the common 'foot length in mm ÷ 5 − 10' rule.
How is the EU size computed?
One Paris point is 2/3 cm, so EU = foot length (cm) × 1.5 + 2. A 26 cm foot gives 39 + 2 = 41, matching the usual EU charts.
Why do UK and US differ by one size?
Both derive from the Barleycorn (1 size = 1/3 inch) but with different zero points: men's UK = foot length (inches) × 3 − 23 and men's US = foot length (inches) × 3 − 22. A 26 cm foot is 10.24 inches, giving UK 7.7 and US 8.7.
What if the result is a decimal?
Round up to the nearest half size, because the forefoot width may not be generous enough. The tool keeps one decimal precisely so you can see which two half sizes it sits between.
Is the measurement uploaded?
No, everything is computed locally in the browser.
