UK to EU shoe conversion
UK and EU numbers are not the same scale. UK sizes step in half sizes; EU uses different numbering entirely. Convert using foot length in cm first, then read UK and EU from a chart.
Men's UK 9 is often near EU 43 for athletic shoes (~27 cm), but brands shift by 0.5 EU. Never assume UK + 33 = EU.
Men's UK to EU (approximate)
| UK | EU | US Men | cm |
|---|---|---|---|
| 7 | 41 | 8 | 26 |
| 8 | 42 | 9 | 26.5 |
| 9 | 43 | 10 | 27 |
| 10 | 44 | 11 | 28 |
| 11 | 45 | 12 | 29 |
Rules that actually work
- Measure foot length in cm—single best anchor.
- Women's UK uses the same number scale as men's UK but different lasts—still use cm.
- Kids' UK is not adult UK minus a fixed number—use kids chart rows.
- Half sizes matter: UK 8.5 sits between EU 42 and 42.5 on many charts.

UK–EU conversion mistakes
Avoid: Adding 33 to UK to get EU
Instead: Use cm-based chart; formula drifts by brand.
Avoid: Using US conversion then guessing EU
Instead: Go cm → EU directly.
Avoid: Ignoring women's UK
Instead: Same UK number ≠ same foot length as men's.
Why UK conversion trips people up
Shoe boxes mix UK 9, EU 43, and cm on the same label. Retail staff sometimes round to the nearest whole size, so your friend’s UK 9 recommendation may not match your foot length.
Athletic brands and dress shoe makers use different lasts. A dress EU size is not guaranteed to match a running EU size at identical numbers.
Kids and youth scales are separate. Never apply adult conversion math to school-age sizes or junior EU numbers.

Who runs long or short at this size

- Adidas: 1/3 EU steps—read 43 1/3 as the 43 row when converting.
- New Balance: Half sizes and wide widths—match cm first.
- Converse Chuck: Runs long—may need 0.5 smaller US than chart athletic size.

Real-world notes on uk to eu shoe size
Charts for uk to eu shoe size summarize typical grading—they are not a guarantee for every season or factory run. When a brand refreshes a last or fit block, reviews often mention it before charts update.
Marketplace listings may ship mixed inventory. Compare the size stamped inside the item on delivery with the chart row you used at checkout.
If you are gifting, ask for body or foot measurements in cm instead of guessing their usual tag size. Gift returns are harder when wear signs appear.
Sales associates can measure you in store; take a photo of the store chart if you later order online from the same brand.
Between online orders, remeasure if your weight changed, you had a foot injury, or you switched sock or insole thickness for running.
Teaching kids their cm size helps them shop later—write foot length inside closet door as a reference.
Document the date you measured—repeat after pregnancy, injury, or major weight change so old numbers do not linger in notes apps.
Measurement hygiene
- Stand weight evenly on both feet when tracing outlines.
- Measure twice on different days if you are between rows.
- For clothing, wear the undergarments you will use with the piece.
- For shoes, match sock thickness to intended use.
- Convert using cm first, then read US/UK/EU from the row—never reverse the order.
- Keep a saved note on your phone with your foot cm and bust/waist/hip cm.
- Update kids' sizes every growth spurt—do not buy multiple seasons ahead.
- Check whether reviews mention 'runs small' for the exact model you chose.
- Prefer free-return windows when trying a new brand last.
- Wide feet: try width SKUs before adding length—see 2E vs 4E shoe width.
