Your size in every chart: EU, US, UK, JP, IT
You are buying a shirt from a German store and it says size 40. Your friend in London asks what size you wear. Your wife brings back a t-shirt from Japan and the tag says 3L. The question: what does any of that mean in one table?
Pick a garment (shirt, suit, t-shirt, jeans), enter the size you already know (EU 40, US 15.5, collar 40 cm) and the converter shows every other value at once. Plus the body measurement in centimeters or inches, so you know what to put the tape measure on.
The converter knows 5 sizing systems: European (EU), American (US), British (UK), Japanese (JP) and Italian (IT). It works for shirts (by collar size), suits and blazers (by chest), t-shirts (by chest, with JP equivalents) and jeans (waist x inseam in inches).
How to use it
- Pick the garment on the top bar: shirt (the button-up kind you tuck in), suit (jacket or blazer), t-shirt (regular knit tee) or jeans (or chinos).
- Pick what you already know: an EU, US or UK size, collar in centimeters (for shirts) or chest in centimeters (for suits and t-shirts).
- Enter or pick the value. The converter shows every other size at once, plus the body measurement in centimeters and inches.
- For jeans: the size is waist x inseam in inches, for example 32W x 32L. Quick rule: EU = waist in inches + 16 (32W is EU 48, 34W is EU 50).
- Below the table you will find brand notes: which brands run small (Zara), which run Asian (Uniqlo) and which are true to size (H&M, Massimo Dutti).
- The how to measure section tells you exactly where to put the tape: base of the neck for shirts, under the armpits for chest, at the waist for pants and from the crotch to the floor for inseam.
When this is useful
A few typical situations where the converter saves you returns and confusion:
- Ordering online from abroad. A German store sells shirts in size 40, a British one in 15.75, an American one in 15.75: is it the same size? Enter it once and see all of them. A 96 cm chest is suit 48 EU, 38 US, 38 UK, 48 IT.
- Buying a gift and not knowing the chart. You know your partner wears L in a t-shirt but the store only has size 50. Check it: L is EU 50, US L, JP LL. Buy with confidence.
- Coming home with an Italian shirt. The tag says IT 50 and the salesperson told you it was your size. The converter confirms: IT 50 is EU 50, US 40, UK 40, chest 101 cm. Either it fits, or you swap it before the tag is gone.
- Buying your first suit. You do not know if you are 48 or 50, and you do not know how that lines up with US 38. You measure your chest under the armpits: 96 cm is EU 48, US 38, IT 48. You walk into the store with a real number.
- Figuring out why a Uniqlo shirt is too small. You bought an L at Uniqlo and it hangs on you like an M. The converter tells you: Uniqlo uses Asian sizing, size up by one. Next time you grab an XL.
- Picking jeans with American labels. Your EU size is 48 but the jeans are tagged 32W x 32L. The converter says: EU 48 is 32 inch waist, 32 inch inseam. You know exactly which pair to pull off the shelf.
