Convert UK shoe sizes to US sizes for both women and men. Despite both using the barleycorn system, UK and US sizes are offset. For men, US sizes are typically 0.5 to 1 size larger than UK. For women, the offset is about 2 sizes. Use this converter when shopping from British retailers like ASOS, Dr. Martens, or Clarks.
Italian brands run smaller — consider sizing up half.

For men, US sizes are typically 0.5 to 1 size larger than UK (a UK 9 is roughly US 9.5 to 10). For women, the offset is larger: a UK 6 is approximately a US 8.
For men, yes. UK and Australian men\'s shoe sizes are identical. For women, Australian sizes are typically 2 sizes larger than UK (a UK 6 is an AU 8).
Yes, Dr. Martens uses UK sizing as their primary system. They do not offer half sizes. If you are between sizes, many recommend sizing down as the leather stretches with wear.
Both systems use the barleycorn (1/3 inch) as the base increment, but they start from different zero points. The UK system starts measurement from a smaller baseline length than the US system.
Yes, the offset between UK and US sizing is consistent across half sizes. For men, add 0.5 to get the US equivalent. For women, add 2. The half-size increments in both systems represent the same physical length difference, so a UK 8.5 converts just as cleanly as a UK 8.
