Men's clothing size chart
Men's tops and shirts convert cleanly because they key on chest measurement. Match your chest to the chart for US, UK and EU sizes and your collar size.
| Size | US / UK | EU | Chest (in) | Chest (cm) | Neck (cm) |
|---|---|---|---|---|---|
| XS | 32 | 42 | 32 to 34 | 81 to 86 | 36 to 37 |
| S | 34 | 44 | 34 to 36 | 86 to 91 | 37 to 38 |
| S | 36 | 46 | 36 to 38 | 91 to 97 | 38 to 39 |
| M | 38 | 48 | 38 to 40 | 97 to 102 | 39 to 41 |
| M | 40 | 50 | 40 to 42 | 102 to 107 | 41 to 42 |
| L | 42 | 52 | 42 to 44 | 107 to 112 | 42 to 43 |
| L | 44 | 54 | 44 to 46 | 112 to 117 | 43 to 44 |
| XL | 46 | 56 | 46 to 48 | 117 to 122 | 44 to 45 |
| XL | 48 | 58 | 48 to 50 | 122 to 127 | 45 to 46 |
| XXL | 50 | 60 | 50 to 52 | 127 to 132 | 46 to 47 |
Men's clothing is easier to convert than women's because the sizes are tied to chest circumference, a real measurement rather than an abstract number. The US and UK share the same numeric size for tops, so a 40 is a 40, while the EU adds about 10 to give a 50. Letter sizes from small to double extra large map onto the same chest bands.
For a dress shirt, the collar matters as much as the chest, so measure around the base of your neck and check the neck column. If your chest and neck point to different sizes, choose the size that fits the part of the garment that has to fit closely. To take the measurements, see how to measure clothing size.
Men's size questions
How do I find my men's clothing size?
Measure your chest at the fullest part and match it to the chart. A 97 to 102 centimetre chest is a medium, which is a US and UK 38 to 40 or an EU 48 to 50.
Are US and UK men's sizes the same?
For tops, yes. Men's tops use the same numeric chest size in the US and UK, so a 40 is a 40 in both. EU sizes run about 10 higher, so a 40 is an EU 50.
How do I find my dress shirt collar size?
Measure around the base of your neck where the collar sits. The chart lists the matching neck size in centimetres for each clothing size.
