Convert men's US shoe sizes to European, UK, and centimetre foot-length equivalents.
Formula
Conversion is performed via a lookup table. Given a US men's size, the corresponding EU size, UK size, and foot length in cm are read directly:
{ EU, UK, cm } = table[US size]
Example anchor point: US 9 → EU 42 → UK 8.5 → 26.2 cm.
How it works
Men's shoe sizes across regions follow established industry conventions rather than a single formula — the converter uses a curated lookup table mapping US sizes 6–13 to their EU, UK, and foot-length equivalents. EU sizes are based on Paris points (⅔ cm increments of the inner shoe length), while US sizes use a different last-length scale, so there is no single linear equation that works perfectly across the full range.
Common mistake: Men's and women's US shoe sizes are offset by approximately 1.5 sizes — a men's US 9 is not the same fit as a women's US 9. Always specify the gender context when converting, and note that half-sizes exist in some markets but are not always available in all EU or UK equivalents.
Worked example
Convert men's US size 9 to EU, UK, and foot length
- Input: US men's shoe size 9.
- Look up size 9 in the conversion table.
- Read off: EU = 42, UK = 8.5, foot length = 26.2 cm.
US men's 9 = EU 42, UK 8.5, foot length 26.2 cm.
Common mistakes to avoid
- Assuming US men and US women sizes are interchangeable -- women sizes run about 1.5 sizes larger than men on the same foot, so a women's 9 is roughly a men's 7.5.
- Using a men's size chart to buy women's shoes in EU sizes -- EU sizes are the same number for both genders based on foot length, but the US numeric offset differs by gender.
- Forgetting that shoe size represents last length (the mold), not exact foot length -- manufacturers add toe room, so a size 10 last does not equal exactly the foot length shown in the table.
Key terms
- US shoe size (men)
- A sizing scale used in the United States and Canada based on the length of the last (the foot-shaped mould). US men's sizes start roughly 1.5 increments above women's for the same foot length.
- EU shoe size
- European shoe sizing measured in Paris points, where one Paris point = ⅔ of a centimetre of inner shoe length. EU sizes are gender-neutral by convention.
- UK shoe size
- British sizing similar to US sizes but typically 0.5 lower than the US men's equivalent for the same foot, based on a barleycorn increment (⅓ inch ≈ 0.847 cm).
- Foot length (cm)
- The actual length of the foot from heel to longest toe measured in centimetres. It is the most universal reference because it bypasses region-specific sizing conventions.
Frequently asked questions
- How do I convert US men's shoe size to EU?
- Use the lookup table: US 9 = EU 42, US 10 = EU 43, US 11 = EU 44. EU sizes are typically 33–34 numbers above the US men's size.
