What this calculator does
International clothing size labels can be difficult to compare. This converter gives broad equivalents for common shopping situations.
Formula used
Women's sizes are mapped from a UK baseline. Men's chest uses inches and centimetres. Children's sizing is shown as age with a broad height estimate.
How to read the result
Use these results as a quick guide only. Garment measurements and brand charts are more reliable for close-fitting clothes.
Assumptions
- Uses broad retail conversions.
- Does not account for fit, cut or garment stretch.
- Children's results are approximate because growth rates vary.
Sources and checks
This calculator uses a standard public formula. Where rules or thresholds can change, source links are listed on the relevant page.
Frequently asked questions
Why do international sizes vary so much?
Countries use different labelling traditions, and brands add their own fit models and grading rules.
