US Women's to AU Shoe Size Conversion

Shopping from a US online retailer? In most cases, US women's shoe sizes and Australian women's shoe sizes are the same number — a US women's 8 is an AU 8. However, this does not apply to all brands, so always check the retailer's own size guide and use the chart below to confirm your size.

Note: US women's sizes are 1.5 sizes larger than AU/UK sizes. US women's 8 = AU 6.5.

Are US and AU Women's Sizes the Same?

This is a common misconception. US women's sizes and AU women's sizes are not the same. AU women's shoe sizes follow the UK standard, which runs 1.5 sizes smaller than US women's. So if you wear a US women's 8, your AU size is 6.5, not 8. Always use the table above when shopping from US retailers.

Tips for Buying US Women's Shoes Online

Always convert your AU size to US using the chart above before ordering.
Measure your foot length in centimetres and use the foot length column to confirm your size.
US shoe sizes do not use half sizes as consistently as AU — if in doubt, go half a size up.
Check whether the retailer is shipping AU-labelled or US-labelled shoes — some international retailers use AU sizing on Australian orders.
Always check the returns policy in case of a sizing mismatch.
