Clothing Size Converter
Convert clothing sizes between US, UK, and EU for tops, bottoms, and dresses.
Separate charts for men and women with measurement guidance.
International clothing size systems vary dramatically between countries. A size 10 in the US, a size 14 in the UK, a size 40 in Europe, and a size 38 in France can all refer to roughly the same garment. This calculator maps sizes across systems using body measurements as the universal reference.
Key body measurements (in inches or cm):
- Bust / Chest — fullest part of chest
- Waist — narrowest point, usually 1 inch above navel
- Hips — fullest point, usually 7–9 inches below waist
US women’s size conversion:
US Size ≈ (Bust in inches − 28) / 2 (approximate, varies by brand)
