Shoe Size Converter - US, UK, EU to CM Calculator & Charts

FAQ

The ShoesGuide chart aligns with official brand data and ISO standards. However, fit varies by model and material. Always check specific 'size reviews' for the shoe you plan to buy.
D is the standard Men's width. 2E is Wide, and 4E is Extra Wide. If standard shoes feel tight on the sides, switching to a 2E model (common in New Balance) can solve your pain without changing the length.
Kids' feet grow fast. Measure from heel to longest toe and add 1.0cm to 1.5cm for growth room. Use our Kids Converter to match this measurement to the correct US/UK/EU size.
Add 1cm to your foot measurement to get your ideal insole length. For example, if your foot is 26cm, look for a shoe labeled as 27cm (or JP 270).
In US sizing, there is a 1 to 1.5 size difference. A Men's US 7 is roughly a Women's US 8.5. Also, Men's shoes are built wider (D width) than Women's (B width).
Generally, yes. Nike shoes tend to be narrow. For models like Air Max or Huarache, go up half a size. However, the Air Force 1 runs large, so size down for that specific model.
Adidas is usually truer to size and slightly wider than Nike. If you wear a US 10 in Nike, a US 9.5 or 10 in Adidas will likely fit well.
Absolutely. A 2E width provides about 5-10mm more circumference around the ball of the foot. It prevents side blowout and improves comfort significantly for wide-footed people.
Chuck 70s run distinctively long. Most people size down half a size (e.g., US 10 -> US 9.5). If you have wide feet, stay true to size and just lace them tightly.
Yes, Vans Old Skool and Authentic styles are the definition of True to Size. Stick to your measured size. For Slip-Ons, size up half a size if you have a high instep.
Always size up. If you are a UK 7.5, buy a UK 8. You can fill the extra space with a thick insole or thick wool socks. Boots that are too small will destroy your heels.
Crocs are designed to be loose. Buying one size up allows for air circulation and comfortable wear with the strap down. They should not hug your foot tightly.
Yes, the sheepskin lining will compress and the leather will stretch. Buy them snug (True to Size). If they feel a bit tight at first, that means they will be perfect in a week.
No. Dress shoes (boots, loafers) run larger than sneakers. If you wear a US 10 sneaker, you are likely a US 9 or 9.5 in dress shoes.
EU sizes don't match up perfectly with US half sizes. The gap between 41 and 42 is about 6.6mm. Rely on the CM/JP measurement on the tag rather than the EU number for accuracy.
Ignore the regional size (US/UK) initially. Look for the CM (Centimeter) or MM measurement on the size chart. This is the universal language of shoe fitting.
Yes. Your feet swell during the day. Always measure or try on shoes in the late afternoon or evening to ensure they won't be too tight after a long day of walking.
Thick athletic or hiking socks can add 2-3mm to your foot volume. Always wear the socks you intend to use when testing new shoes.
Yes. Adding a foam insole can take up about half a size of volume. Heel grips can also stop your heel from slipping out of a slightly long shoe.
Avoid completely flat shoes like Converse or Vans for long walks unless you add an aftermarket arch-support insole. Your feet need structural support to prevent fatigue.
