Size Chart & Conversion Tool

Convert women's clothing, men's clothing and adult shoe sizes between countries, and see the body measurements behind each size.

A US 8 is not an 8 everywhere. This Apparel Search tool lines up US, UK, European, Italian, French, Japanese and other sizes, shows the measurements typically behind each one, and lets you download the full chart for hangtags, spec sheets or an online size guide. It runs in your browser, and nothing you enter is saved.

How accurate is this? Shoes follow formulas. Clothing follows conventions. Shoe sizes in each system are mathematically linked, so those conversions are reliable to about half a size, though brands still differ. Clothing sizes are not defined by one international rule. They are commonly published relationships, and the published charts disagree with each other, so where they differ we show the range. Brand, fabric, cut and vanity sizing can move a garment by a size or more. Always check the brand's own size chart.

Why sizes don't match

Body measurements versus garment measurements. A size label describes the body it is meant for. The garment itself is larger by an amount called ease, which differs by style.
Clothing sizes are conventions. No single international rule sets them, and brands adjust over time. Vanity sizing means the same label can fit a larger body than it once did.
Shoes are more systematic. The European system counts steps of 2/3 cm (the Paris point), the UK counts steps of 1/3 inch, US men's is UK plus 1 and US women's is US men's plus 1.5. The ISO 9407 Mondopoint system uses foot length in millimeters. Last shape, toe room and width still change the fit.

Where the numbers come from. Shoe conversions use the formulas above. Women's and men's clothing use commonly published conversion relationships and body-measurement ranges from retailer size charts, and where two charts differ we show the range. Sizes at the very small and very large ends of the women's chart come from a single chart. Japanese sizes are approximate. Foot length shown for shoes is an estimate, since toe room varies. Brand-specific charts always take priority.
