Men's Clothing Size
A general men's top size chart: chest decides, waist cross-checks. Get your letter size with US chest-inches and EU numbering highlighted.
How to use
- Measure around the fullest part of your chest, arms relaxed.
- Add your natural waist measurement for a cross-check.
- Optionally add shoulder width (across the back) for tailored-fit tie-breaking.
- Enter the numbers and read the highlighted row.
Frequently asked questions
How do I convert between letter sizes and US chest sizes?
The US column shows the chest circumference in inches each letter typically covers — M is anchored around 40", L around 42–44". The letter scale is shorthand for those numbers, which is why the same letter can drift a step between brands. The EU column follows the other common convention: roughly half your chest in centimeters (a 100 cm chest → EU 50).
Should I size by chest or by waist?
For tops, chest — the shoulders and chest have to slide through first. The waist column catches the opposite case: if your chest says M but your waist says L, untucked and stretch styles will fit at M while tailored shirts need the larger size. The calculator always recommends the larger of the two.
Do I need the shoulder measurement?
It is optional here, but it is the usual tie-breaker for tailored shirts and jackets: measure across the back, from one shoulder seam point to the other. If your chest and waist both say M but your shoulders are 47+ cm, a size up (or a raglan/cut-on sleeve) saves the tight upper back.
Do these sizes work for knitwear and t-shirts?
Broadly yes, with a bias: t-shirts and knitwear stretch, so the lower edge of your band is comfortable; woven shirts and jackets do not, so lean to the upper edge or one size up.
Where should I measure my chest?
Around the fullest part, under the armpits and across the shoulder blades, arms relaxed at your sides. Breathe normally — measuring after a deep inhale adds a size you will regret.
What does it mean when the tool says “closest match”?
One of your measurements fell outside every band in the chart, so it picked the nearest row. Double-check the measurement first — a tilted or loose tape is the usual cause — then treat the result as a starting point, since sizing varies by brand.
