UK to US Sock Size Conversion

| 9-11 | L (10-12) |
Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.
A UK shoe-size range of 6-8 lands on a US 7-9 sock range on the standard chart — worth checking before ordering socks from a US retailer that only lists its own domestic range.
Because sock ranges are wide by design, a UK shopper whose foot sits near the edge of a stated range generally has more flexibility than the equivalent shoe conversion would suggest — the stretch built into the knit absorbs small size differences.
As with any sock purchase, the printed range is a starting point rather than a precise fit — a thicker athletic sock at the top of its stated range fits differently than a thin dress sock at the same nominal size.
Frequently asked questions
Is UK-to-US sock conversion as strict as shoe conversion?
No — sock ranges are intentionally broad, so there's more tolerance for being near a boundary than there would be buying an actual shoe at that size.
