Sizes usually look like 40R. The number shows chest inches; the letter shows jacket length: S (short), R (regular), L (long). US and UK sizes use inches. EU sizes use centimeters and sit about 10 sizes higher (US 40 = EU 50). Pants use waist × inseam (for example, 32x30). A good suit size calculator for mens will handle all this and match US, UK, and EU charts.
Grab a flexible tape and stand straight. If possible, have someone help. Measure on a thin shirt or directly on skin. Don’t measure over heavy clothes.
Wrap the tape around the fullest part of your chest, under the armpits. Keep the tape level and breathe normally.
Measure at your natural waist, just above the belly button. Don’t pull the tape tight.
With feet together, measure the widest part of your hips.
Measure around the base of your neck where a collar sits. Add half an inch for comfort.
Measure from one shoulder seam point to the other across your back.
From the middle of your neck, over the shoulder, down to the wrist. Bend your arm slightly.
From the crotch seam to the ankle.
These help the tool adjust the fit and recommend the best cut.
After you finish, plug the numbers into the best suit size calculator you trust. If you need UK charts, try a men's suit size calculator UK or suit size calculator UK men's. For jackets, use a men's suit jacket size calculator or suit jacket size calculator to fine-tune the fit.
International sizes confuse many. Quick rule: add 10 to a US/UK size to get EU size (US 40 = EU 50).
| US/UK | EU | Chest (in) |
|---|---|---|
| 34 | 44 | 34 |
| 36 | 46 | 36 |
| 38 | 48 | 38 |
| 40 | 50 | 40 |
| 42 | 52 | 42 |
