The Complete Jersey Size Guide: Measure Once, Cheer in the Right Fit
Updated September 18, 2026 · 7 min read
1. How to measure yourself
Take measurements over a thin t-shirt (never outerwear), standing relaxed with arms at your sides. A soft tape measure is best; if you only have string, wrap it, mark it, then measure against a ruler.
- Chest (most important): around the fullest part of your chest, just under the armpits, tape parallel to the floor.
- Waist: your natural waistline, the narrowest part of your torso.
- Body length: from the highest point of the shoulder (by the collar) down to where you want the hem.
- Sleeve: shoulder seam to wrist, for long-sleeve jerseys and jackets.
- Inseam: crotch to ankle, for pants.
Measure chest straight across the fullest part; body length from the shoulder seam to the hem.
2. Fit by league
Not all jerseys are cut the same. Know the silhouette before you pick a size:
| League | Fit type | How it should feel |
|---|---|---|
| Soccer | Athletic / slim | Close to the body; size up for a looser look |
| NBA | Standard / long | Relaxed through the chest, longer hem |
| NFL | Roomy / boxy | Classic oversized game-day look |
| MLB | Full / button-front | Relaxed traditional baseball cut |
| NHL | Very loose | The loosest cut of all; order your true size |

| 3XL | 51–55" | 49–52" | 53–58" | 52–56" | 55–58" |
NHL jerseys naturally run 1–2 sizes roomier than soccer or NBA of the same label — a 40" chest wears an NHL S the way it wears a soccer L.

How do I measure myself for a jersey?
Use a soft tape measure over a thin t-shirt. Chest is the key number: measure around the fullest part of your chest, just under the armpits, with the tape parallel to the floor. Also note waist (for shorts/pants) and body length (shoulder seam to where you want the hem). If you are between two sizes, size up.
Do jerseys run big or small?
It depends on the league. Soccer jerseys are the slimmest, most athletic cut; NBA is standard; NFL and MLB are roomy; NHL hockey jerseys are the loosest of all. Match your chest measurement to the chart for your league rather than guessing from your t-shirt size.
I'm between two sizes. Which should I pick?
Size up for every league except NHL. Jerseys are casual wear meant to be relaxed, and a little extra room always looks better than a snug fit. NHL already runs very loose, so stay at your true size there.
Should I buy men's or women's jerseys?
Women's jerseys have a tapered, contoured waist; men's are cut straight and boxy. Many fans prefer the men's fit for the classic oversized look. A woman ordering a men's cut should usually go one size down from her women's size.
Do I wear the same size in jerseys, shorts and jackets?
Usually close but not always. Jerseys and jackets size by chest; shorts and pants size by waist and hip. It is common to wear a jersey L but shorts M, so always check the chart for the specific product type.
What if the size still isn't right?
