Frequently asked questions
What size NBA jersey should I buy?
Measure your chest, find the row in the chart above that contains it, and take that size. If you are between two rows, go smaller for a closer fit or larger for a looser fit or for layering.
Are jerseys true to size?
Not always. Fit depends on the maker and the tier: on-field style cuts tend to be closer to the body and fan versions looser. Use the maker's own chart for the exact product, and size up if you plan to layer.
How do I measure my chest for a jersey?
Wrap a soft tape measure around the fullest part of your chest, under the arms and across the shoulder blades, keeping it level. Breathe out normally and do not pull the tape tight.
What if I am between two sizes?
Nike's guidance is to order the smaller size for a tighter fit or the larger size for a looser fit. If you want to layer a hoodie or thermal shirt underneath, take the larger one.
Is a size chart a body chart or a garment chart?
The charts on this site are body measurements, as published by the maker. Some retailers publish garment measurements instead, so never mix numbers from two different charts.
Do NBA jersey sizes differ between tiers?
Often, yes. Tiers can be cut differently, and a closer-fitting tier may need a size up. Check the chart that applies to the tier you are buying.
Does this tool store my measurements?
No. The finder runs entirely in your browser; your numbers are not sent anywhere, saved or shared.
