About New Era

New Era has been the official on-court cap maker of the NBA since 2018, producing the fitted and adjustable caps worn by players, coaches, and fans during every game. The 59FIFTY fitted and 9FIFTY snapback are the two flagship styles, with team-specific colorways released each season. New Era caps use head circumference for sizing -- measure around the widest part of your head, just above the ears.

Beyond the NBA, New Era supplies official headwear for the MLB, NFL, and dozens of global sports leagues, making it the world's most recognized cap brand. From draft night fitteds to everyday snapbacks, New Era connects sport and street culture through a single silhouette. Use the tables below to match your head measurement to the right cap size.
