What is the standard size of a hockey puck?

The standard size of a hockey puck is 3 inches in diameter. This measurement is consistent across professional leagues, including the NHL, and helps maintain uniformity in play. The puck also has a thickness of 1 inch and weighs between 6 ounces and 6.5 ounces.

Options indicating larger diameters, such as 4, 5, and 6 inches, do not conform to the regulations set by governing bodies overseeing the sport. Larger pucks would not fit the gameplay and could drastically affect how the game is played, including how players shoot, pass, and handle the puck. The regulation size ensures that players can develop their skills using the same dimensions across various levels of competition.
