27 cm
European size 42 corresponds to a 27 cm foot
About EU size 42
- European size 42 corresponds, by the Continental rule, to a foot of 27 cm.
- For men, that is UK 8 and US 9.
- For women, that is UK 8 and US 10.5.
- This chart is a common retail approximation, not a standard — every manufacturer keeps its own, slightly different, chart. The reliable move is to measure the foot and compare its length against the manufacturer's own chart.
Examples
What you get
Foot length first
Every EU size starts from the foot length in centimetres — the one number no manufacturer can redefine.
Men and women, on the same page
Every EU size shows the UK and US equivalent for both men and women, wherever the scale reaches.
No false promises
Size charts differ between manufacturers — the page says so plainly, instead of giving a number as if it were a certainty.
Nothing is stored
The size you choose stays on your page. We do not store it or send it anywhere.
How it works
- Choose the European (EU) size.
- See the foot length in centimetres and the UK and US equivalents.
- Compare against the manufacturer's own chart before you buy.
Worth knowing
How the EU size is worked out
The EU size follows the Continental rule: foot length in centimetres is the size minus 1.5, multiplied by two-thirds. It is a fixed formula — unlike UK and US sizes, which are separate retail conventions, not derived from the same rule.
Why the chart is not a certainty
Every manufacturer rounds foot length to a size slightly differently, so the same EU number can come out a little different from one brand to the next. The chart above is a common retail approximation, not a universal standard — the reliable move is to measure the foot and compare against the manufacturer's own chart.
Frequently asked questions
Can I fully trust this chart?
Not entirely — it is a common retail approximation, not a standard. Every manufacturer keeps its own chart, slightly different from this one.
How do I find my actual size?
Measure the foot length, in centimetres, and compare it against the chart published by the manufacturer you are buying from — not a general chart.
Why do the UK and US sizes differ for men and women?
Because UK and US are separate retail scales, not derived from the same formula as the European size — each market built its own.
Why do some sizes have no women's equivalent?
Because the women's scale typically stops at EU 44 — sizes 45 to 47 in this table only have a men's equivalent.
