Women's size chart
The calculator matches your bust measurement against this chart, then checks your waist and hips against the same row. The systems are related by fixed offsets: UK = US + 4, German/EU = US + 32, French = German + 2, Italian = German + 4.

Men's suit & shirt sizes
Men's suit and jacket sizes are the chest measurement in inches: US and UK use the same number, and the EU size is that number plus 10. Shirt sizes are based on the collar measurement.

About the clothing size calculator
Sizing systems differ mostly by a fixed offset, so once your measurements land on a chart row, every other system follows from it. This tool keeps the whole chart visible so you can double-check the match before you order. Everything runs in your browser and nothing is uploaded. For more conversions, see all size conversion charts or try the shoe size converter.
Questions
What is a European size 38 in US?
A women's European/German size 38 is a US 6 (UK 10, French 40, Italian 42) — roughly a small, fitting a bust of about 88 cm.
Are German and French sizes the same?
No. French sizes run two numbers higher than German/EU sizes (FR = DE + 2), so a German 38 is a French 40. Italian sizes are four higher than German (IT = DE + 4).
Do sizes vary between brands?
Yes. These charts follow common standards, but individual brands cut differently and some use vanity sizing. Treat the result as a starting point and check the brand's own chart when possible.
Is anything uploaded?
No. Your measurements never leave your device — the calculation runs entirely in your browser, free and without sign-up.
