Sneakers Size Conversion Chart
The conversion table below turns a sneaker size from one system into the others, covering US women's, US men's, UK and EU sizes. Find your size in the column you know, then read across the row for the matching sizes. These are broad general conversions, not exact brand equivalents, because brands grade their sizes differently and some use their own EU numbering. When you order, always check the converted size against the brand chart for that pair.
The general sneakers conversion table
Use this table to convert a sneaker size between systems. Read across one row: the US women's, US men's, UK and EU sizes in that row are the broad general equivalents for the same foot length. The table is built from foot length, not from brand labels, so it stays consistent even when two brands print different numbers on the same length.
Start from the system you know best, usually the one printed inside your current sneakers. If you know your US women's size, find it in the first column and read across. If you only know your foot length, use the size chart first to find your base size, then convert from there. For the full background on international shoe sizing, see US, UK and EU shoe size conversion.
Conversion table
| US women's | US men's | UK | EU |
|---|---|---|---|
| 5 | 3.5 | 3 | 35.5 |
| 5.5 | 4 | 3.5 | 36 |
| 6 | 4.5 | 4 | 36.5 |
| 6.5 | 5 | 4.5 | 37.5 |
| 7 | 5.5 | 5 | 38 |
| 7.5 | 6 | 5.5 | 38.5 |
| 8 | 6.5 | 6 | 39.5 |
| 8.5 | 7 | 6.5 | 40 |
| 9 | 7.5 | 7 | 40.5 |
| 9.5 | 8 | 7.5 | 41 |
| 10 | 8.5 | 8 | 42 |
| 10.5 | 9 | 8.5 | 42.5 |
| 11 | 9.5 | 9 | 43 |
| 11.5 | 10 | 9.5 | 43.5 |
| 12 | 10.5 | 10 | 44.5 |
Notice the pattern in the table. US women's sizes run about one and a half sizes above US men's sizes for the same foot, UK sizes run about one size below US men's sizes, and EU sizes jump by roughly one number per half size in US sizing. Knowing the pattern helps you spot a conversion that looks wrong on a product page, such as a UK size printed equal to the US men's size.
US women's to US men's conversion
Converting between US women's and US men's sneaker sizes is the most common switch, because many sneakers are sold in men's sizing only or listed with both scales. As a broad general rule, subtract one and a half sizes from the women's size to get the men's size. A women's size 9 converts to about a men's size 7.5, and a women's size 7 converts to about a men's size 5.5.
The width may change with the scale, because men's lasts are often built a little wider than women's lasts for the same length. If you have a narrow foot and you switch from women's to men's sizing, check the width carefully, and consider whether the model comes in a narrow or regular width in the men's scale. The converted size is a starting point, not a guarantee.
UK and EU conversions
UK sneaker sizes run about one size below US men's sizes for the same foot length, so a US men's size 8 converts to about a UK size 7, and a US women's size 9.5 converts to about a UK size 7. The UK system is used by many brands based in the UK and by some international brands, so it appears often on product pages that ship worldwide.
EU sizes use larger numbers and a different step, with about one EU number per half US size. A US men's size 8 converts to about an EU size 41, and a US women's size 8 converts to about an EU size 39.5. Some brands skip certain EU half sizes, so a foot length between two EU sizes may need a choice based on width and use. When in doubt, convert from foot length rather than from another size label, because foot length is the same in every country.
Why conversions differ between brands
Conversions differ between brands because each brand builds its sizes on its own last, the foot shaped form the shoe is made around, and grades its sizes by its own step. One brand may grade by a third of an inch per size and another by a slightly larger step, so the same foot can sit in a different labelled size. EU numbering adds another layer, because some brands use a continental EU scale and others use a slightly different one.
That is why a conversion table should always be checked against the brand chart for the pair you are buying. If the brand chart lists foot length in centimetres, compare your measured foot length directly with that column and ignore the converted label. If the brand chart lists insole length instead, remember that the insole is longer than the foot, so leave about a thumb width of room in the number. For more on why labels differ, see why shoe sizes vary between brands.

Frequently Asked Questions
What is a US women's size 8 in UK sneaker sizing?
As a broad general conversion, a US women's size 8 is about a UK size 6, but brands vary, so check the brand chart.
What is a US men's size 9 in EU sneaker sizing?
As a broad general conversion, a US men's size 9 is about an EU size 42.5, but some brands use slightly different EU numbering.
How do I convert US women's to US men's sneaker sizes?
Subtract about one and a half sizes from the women's size to get the men's size, then check the width, since men's lasts are often a little wider.
Why does the same size convert differently on two websites?
Brands grade their sizes differently and use different EU scales, so one site may round up where another rounds down. Convert from foot length when you can.
Should I convert from my size or from my foot length?
From foot length when you can, because foot length is the same in every country, while size labels are rounded by each brand.
