EU to US to UK Shoe Sizes: The Table Lies at the Edges
Conversion charts are averages. Your foot is not an average.
Updated 2026-10-30
Why charts disagree with each other
Brands round differently and men's versus women's scales are offset inconsistently. Two charts can differ by a full size at the ends of the range.
Use the chart only to get close, then confirm with a centimetre measurement.
Centimetres are the common language
Measure your foot length and the insole of a shoe that fits. The difference between those two numbers is your personal allowance.
Once you know your allowance, any listing with an insole measurement becomes reliable — regardless of the label.
Where the edges break
Small sizes and large sizes drift most, because brands produce fewer of them and grade the lasts differently.
If you are at either end of the range, never convert — always measure.
A habit that ends sizing mistakes
Keep a note with two numbers: your foot length and your allowance. Send both to the agent with every shoe order.
It takes one minute and removes the single most common reason people reject a parcel at QC.
FAQ
Is EU sizing the same across brands?
No. EU is a range, not a standard, and brands interpret it differently.
Do women's and men's charts match?
Only approximately, and the offset varies by brand. Measure instead.
Can I trust 'true to size' claims?
As a starting point. It means the brand's own chart, which may not match your foot.
