What is the diameter of a standard hockey puck in inches? A standard hockey puck is 3 inches in diameter.
The official NHL puck is a flat, circular disk made from vulcanized rubber. League specifications set its diameter at 3 inches and its thickness at 1 inch, giving it the familiar compact shape used in ice hockey.
The puck also has a regulated weight of 5½ to 6 ounces. It is commonly frozen before games because chilling makes the rubber less bouncy and helps it slide more predictably across the ice. Teams keep a supply of frozen pucks ready for play.
A frequent mix-up is confusing the puck’s diameter with its thickness: the puck is three inches across but only one inch high. Players may use specially marked practice or commemorative pucks, but regulation game pucks follow the same basic dimensions.
