AMERICAN JERSEY SIZE GUIDE
These are finished jersey measurements—not body measurements. For the best comparison, measure a jersey you own flat from armpit to armpit and double that number.
| SIZE | FULL CHEST | LENGTH | SHOULDER |
|---|
| S | 41.7 in | 28.7 in | 18.1 in |
| M | 44.1 in | 29.5 in | 18.9 in |
| L | 46.5 in | 30.3 in | 19.7 in |
| XL | 48.8 in | 31.1 in | 20.5 in |
| 2XL | 51.2 in | 31.9 in | 21.3 in |
| 3XL | 53.5 in | 32.7 in | 22.0 in |
| 4XL | 55.9 in | 33.5 in | 22.8 in |
If you are between sizes or prefer a looser baseball fit, choose the larger size.02
