Clothing sizes vary widely between the US, UK, EU, and Asian sizing systems. Learn how to convert your size accurately and avoid buying the wrong fit.
Step-by-Step Guide
Take your measurements
For tops/jackets: measure chest (fullest part) and waist. For bottoms: measure waist and hips. For dresses: measure bust, waist, and hips. Use a soft tape in centimeters.
Understand the size systems
US sizes are numeric (S/M/L or 0/2/4…). UK sizes are typically 2 higher than US (US 8 = UK 10). EU sizes are numeric (EU 36 ≈ US 6). Asian sizes (JP/KR) run smaller—check the chart.
Use our size conversion chart
Open the Clothing Size Chart tool, select garment type, enter your measurement or known size in one system, and get the equivalent in all others.
Check brand-specific sizing
Sizes vary between brands. Always check the brand's own size guide when available—especially for fast fashion and international brands.
When in doubt, size up
If you fall between sizes, size up for comfort. Tailoring clothes smaller is easier than stretching them larger.

Frequently Asked Questions
Q: What does "one size fits all" mean?
A: "One size" typically fits a US XS–M range. Check the brand's measurements to confirm it fits your body.
Q: How do I measure myself accurately?
A: Stand straight and relaxed. Wrap the tape snugly (not tight) around the fullest part of the area. Measure in cm for best accuracy.
Q: Why do EU and US sizes differ so much?
A: EU numeric sizes are based on body measurements in centimeters (EU 36 = 36 cm bust half-circumference). US sizes evolved from older catalog systems without a direct measurement basis.
