How do NBA jersey sizes run?

Standard US athletic sizing. If you're between sizes, sizing up gives a looser, on-court-inspired vibe.

Does it run small or large?

It's built true to standard sizing. If you're between sizes, most fans take the larger one for comfort on long matchdays.

What age range does youth sizing cover?

Youth sizes typically span kids through early teens. Check the size chart measurements — chest width is the best guide for choosing.

Does it come in other colors?

This product page shows one colorway, but the team's home, away, and third looks are available across the store — check the collection for more options.
