How to measure ring size: Wrap a thin strip of paper around your finger, mark where it overlaps, measure the length in mm — that is your circumference. Find that number in the table above.
Quick Answer: Women's US size 8 = UK 6 = EU 39 = AU 8.5. Men's US size 10 = UK 9.5 = EU 43 = AU 10. Clothing sizes vary significantly by brand — these tables are standard guides.

Why Sizes Differ Between Countries

Shoe sizes evolved independently in different countries before any international standard existed. The European (Paris Point) system measures in units of ⅔ of a centimetre. The UK system uses barleycorns (⅓ of an inch). The US system is similar to the UK but with a half-size offset for women and a full-size offset history. Australia generally follows the UK system for shoes but uses US-based sizing for clothing.

Clothing sizes are even less standardised — they are defined by each brand rather than a regulatory body, which is why a medium from one brand may fit like a large from another. When shopping online internationally, always check the specific brand's size chart and take your own measurements.
