Men's Clothing Size: US to Intl
This page converts men's clothing sizes from the US system to the international (S–XXL) system. It is the quick reference you need when shopping from foreign retailers, where the same garment carries very different numbers depending on the country of origin.
For example, a men's US 40 is typically a international M. International labels use letters (S, M, L) rather than numbers, so expect a range rather than an exact match.
Keep in mind that clothing equivalences are a starting point, not a guarantee: so-called vanity sizing means two brands can label a garment of identical measurements differently. So alongside this chart, it is worth checking each brand's own size guide and, above all, looking at the actual measurements in centimetres.

How to take your measurements
To get a men's size right, measure your chest around the fullest part with the tape horizontal and your arms relaxed, and your waist around the navel. Compare those measurements in centimetres against the chart; many brands label shirts by chest measurement directly.
Measure over a thin shirt rather than bulky clothing, and keep the tape snug but not tight for a realistic size.
Frequently asked questions
What international (S–XXL) size is my US men's size?
Select your US size in the calculator and we show the equivalent international (S–XXL) size for men's clothing. Use it as a starting point and confirm with the brand's measurements.
Why does the same size fit differently between brands?
Because of vanity sizing: each brand tweaks its patterns, so two garments of the same nominal size can have different measurements. Go by the actual measurement in centimetres where you can.
Does this chart work for every type of garment?
It is a general size equivalence. For closely fitted or structured pieces (jeans, suits), always check the brand's specific size guide.
