Measure a jersey you already own: lay it flat and measure straight across the chest from armpit to armpit, then from the top of the shoulder to the bottom.
| Size | Chest (inches) | Length (inches) |
|---|---|---|
| XS | 18 | 25 |
| S | 19 | 26 |
| M | 20 | 27 |
| L | 21 | 28 |
| XL | 22 | 29 |
| XXL | 23 | 30 |
Tip: Player-edition jerseys have a slim, athletic fit — if you're between sizes, go one size up.
