Size Guide

Fan Jersey Guide · Sizing

NBA jerseys are cut looser than regular T-shirts. Measure your chest and use the chart below — and check the fit notes, because each tier is cut differently.

In short

Measure around the fullest part of your chest and match it to the chart. If you're between sizes, size up for a relaxed on-court feel. Authentic jerseys are cut to the on-court specification and fit closest to what players wear; Swingman is a slightly looser fan cut; Replica is the lightest and most relaxed.

How to measure

Chest: measure around the fullest part, keeping the tape level and snug but not tight.
Length: measure from the top of the shoulder down to where you want the hem to sit.
If you're between two sizes, choose the larger one.

Youth and toddler sizes

Youth jerseys follow the same chest measurement method. If your child is between sizes or growing fast, size up — the relaxed cut makes that comfortable. Toddler sizes run small; check the product page for the specific chart.

Tips before you order

Jerseys are designed to be worn loose over a tee — that's normal, not a sizing error.
Washing cold and drying low helps prevent any shrinkage. See our jersey care guide.

FAQ

Should I size up for an NBA jersey?

If you prefer a relaxed fit, are between sizes, or want to layer over a hoodie, size up. For a closer fit stay true to size.

Do Authentic jerseys fit differently?

Yes. Authentic jerseys are built to the on-court specification and have an athletic cut, so many fans go one size up compared with Swingman.

Are the sizes US or EU?

Our charts show inches and centimetres. Compare your own chest measurement rather than converting your usual clothing size.

What if the size I ordered doesn't fit?

Unworn jerseys with tags attached can be returned within 30 days — see the returns page for the full process.
