How to Measure Yourself
Grab a soft tape measure and wear a thin t-shirt. Two numbers are all you need.
| Measurement | How to Take It | Why It Matters |
|---|---|---|
| Chest | Wrap the tape under your armpits around the fullest part of your chest. Keep it level, snug but not tight. | The #1 sizing number for every league chart below. |
| Length | Measure from the highest point of your shoulder straight down to where you want the hem to sit. | League cuts vary — hockey and football run longest. |
NFL Jersey Sizing — Football Jerseys
NFL fan version jerseys are cut roomy for layering over hoodies on cold gamedays. The shoulders are generous, the sleeves hit mid-bicep, and the body is boxy by design — that is how football jerseys are meant to be worn.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| XS | 32-35 | 81-89 | 27 | 69 |
| S | 35-37.5 | 89-95 | 28 | 71 |
| M | 37.5-41 | 95-104 | 29 | 74 |
| L | 41-44 | 104-112 | 30 | 76 |
| XL | 44-48.5 | 112-123 | 31 | 79 |
| XXL | 48.5-53.5 | 123-136 | 32 | 81 |
| 3XL | 53.5-58 | 136-147 | 33 | 84 |
| 4XL | 58-63 | 147-160 | 34 | 86 |
| 5XL | 63-68 | 160-173 | 35 | 89 |
NBA Jersey Sizing — Basketball Jerseys
NBA fan version jerseys are sleeveless with a longer, straight body — the classic on-court cut. Armholes are cut deep so the jersey moves with you, whether you wear it solo in summer or over a t-shirt.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| XS | 32-35 | 81-89 | 26 | 66 |
| S | 35-37.5 | 89-95 | 27 | 69 |
| M | 37.5-41 | 95-104 | 28 | 71 |
| L | 41-44 | 104-112 | 29 | 74 |
| XL | 44-48.5 | 112-123 | 30 | 76 |
| XXL | 48.5-53.5 | 123-136 | 31 | 79 |
| 3XL | 53.5-58 | 136-147 | 32 | 81 |
| 4XL | 58-63 | 147-160 | 33 | 84 |
| 5XL | 63-68 | 160-173 | 34 | 86 |
MLB Jersey Sizing — Baseball Jerseys
MLB fan version jerseys are button-up with a relaxed, straight cut. Because the front opens, the fit is more forgiving than a pullover; the back half is where your chest measurement matters.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| XS | 32-35 | 81-89 | 28 | 71 |
| S | 35-37.5 | 89-95 | 29 | 74 |
| M | 37.5-41 | 95-104 | 30 | 76 |
| L | 41-44 | 104-112 | 31 | 79 |
| XL | 44-48.5 | 112-123 | 32 | 81 |
| XXL | 48.5-53.5 | 123-136 | 33 | 84 |
| 3XL | 53.5-58 | 136-147 | 34 | 86 |
| 4XL | 58-63 | 147-160 | 35 | 89 |
| 5XL | 63-68 | 160-173 | 36 | 91 |
NHL Jersey Sizing — Hockey Jerseys
NHL fan version jerseys are the roomiest cut we carry — built for the ice, where players pad up underneath. Extra-long sleeves, a big angular shoulder line, and a hem that drops well below the waist.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| XS | 34-37 | 86-94 | 29 | 74 |
| S | 37-40 | 94-102 | 30 | 76 |
| M | 40-43 | 102-109 | 31 | 79 |
| L | 43-46 | 109-117 | 32 | 81 |
| XL | 46-50 | 117-127 | 33 | 84 |
| XXL | 50-55 | 127-140 | 34 | 86 |
| 3XL | 55-60 | 140-152 | 35 | 89 |
| 4XL | 60-65 | 152-165 | 36 | 91 |
| 5XL | 65-70 | 165-178 | 37 | 94 |
NCAA Jersey Sizing — College Jerseys
NCAA fan jerseys follow the cut of their pro counterparts — college football jerseys wear like NFL, college basketball wears like NBA, college hockey like NHL. Check which sport your team plays and use that league chart.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| XS | 32-35 | 81-89 | 27 | 69 |
| S | 35-37.5 | 89-95 | 28 | 71 |
| M | 37.5-41 | 95-104 | 29 | 74 |
| L | 41-44 | 104-112 | 30 | 76 |
| XL | 44-48.5 | 112-123 | 31 | 79 |
| XXL | 48.5-53.5 | 123-136 | 32 | 81 |
| 3XL | 53.5-58 | 136-147 | 33 | 84 |
| 4XL | 58-63 | 147-160 | 34 | 86 |
| 5XL | 63-68 | 160-173 | 35 | 89 |
Soccer Jersey Sizing — Soccer Jerseys
Soccer fan version jerseys are the slimmest cut we carry — athletic and close to the body, just like the kits on the pitch. There is little room for layering; this is a summer-fit jersey.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| XS | 32-35 | 81-89 | 26 | 66 |
| S | 35-37 | 89-94 | 27 | 69 |
| M | 37-40 | 94-102 | 28 | 71 |
| L | 40-43 | 102-109 | 29 | 74 |
| XL | 43-47 | 109-119 | 30 | 76 |
| XXL | 47-52 | 119-132 | 31 | 79 |
| 3XL | 52-57 | 132-145 | 32 | 81 |
| 4XL | 57-62 | 145-157 | 33 | 84 |
| 5XL | 62-67 | 157-170 | 34 | 86 |
