Size Guide
Size Guide
One league, three charts, zero guesswork. Every number below is a body measurement — inches and centimetres side by side — across men’s, women’s and youth NFL kit. Measure once, read your row, and if you would like a second opinion before your parcel is packed, send us the numbers and we will check them against these charts for you.
The tape, not the guess
How to measure
Ninety seconds with a soft tape measure settles what no amount of label-squinting will. Wear a single thin layer, stand the way you normally stand, and let the tape touch you without squeezing. No tailor’s tape? Use a piece of string, pinch where it meets, then lay it against a ruler.
Right number, right chart
Which number decides
Most sizing mistakes are measurement mismatches — a waist compared against a chest, or a flat-laid garment width read as a body number. This page uses body measurements throughout. Confirm the deciding number here:
Which measurement decides which NFL garment.
| Garment | Decides the size | Double-check with |
|---|---|---|
| Men’s & women’s jerseys | Chest | Body length |
| Youth jerseys | Age band | Chest & height |

Broad through the chest already, or planning to wear it over a hoodie? Order one size up from your row. Otherwise your true size is the right call.
Tapered, not shrunk
Women’s NFL chart
The women’s cut follows the body through the waist and finishes higher on the hip. Six sizes, XS through 2XL.
NFL jersey — women’s, tapered through the waist, body measurements.
| Size | Chest (in) | Chest (cm) | Waist (in) | Length (in) | Length (cm) |
|---|---|---|---|---|---|
| XS | 31–33 | 79–84 | 25–26 | 26 | 66 |
| S | 33–35 | 84–89 | 26–28 | 27 | 69 |
| M | 35–38 | 89–97 | 28–31 | 27.5 | 70 |
| L | 38–41 | 97–104 | 31–34 | 28 | 71 |
| XL | 41–44 | 104–112 | 34–37 | 28.5 | 72 |
| 2XL | 44–47 | 112–119 | 37–40 | 29 | 74 |
If the loose, boxy silhouette is what you are after, a men’s small or medium does that job better than sizing up the women’s rows.
