Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

Below is this week's segment – Basketball Measurements - Listen

If you’ve seen the movie “Hoosiers,” you know that a basketball rim is 10 feet above the ground. That’s the same if you are in the gym at Beaver Island High School or at Little Caesars Arena. But what are the other court dimensions?

To start – courts are typically 84 feet long but can be up to 94 feet long. They are 50 feet wide.

The free throw line is 15 feet from the face of the backboard and the high school 3-point line is 19 feet, 9 inches from the basket.

Each hoop is a circle, 18 inches in diameter.

The boys play with a basketball 29½ inches in circumference, the girls with one 28½ inches in circumference.

And believe it or not, two girls balls will go through a standard rim at the same time.

Be the Referee: Field Hockey Substitution

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

Below is this week's segment – Field Hockey Substitution - Listen

We are on the pitch today for a field hockey “You Make the Call.”

During the execution of a penalty corner, the defending goalkeeper is struck on the hand and cannot continue. How is play resumed?

  • Allow a properly equipped goalkeeper to substitute.
  • Disallow any substitution; the injured goalkeeper must remain in the game.
  • The defending team shall forfeit.

If you said to allow the substitution, you are correct. Under Rule 4-4-3, a goalkeeper substitution is permitted during a penalty corner in the event of injury or suspension. Once the new goalkeeper is ready, resume play with the continuation of the penalty corner.

Field players, however, may not substitute until the penalty corner has been completed. This ensures proper game flow while prioritizing player safety.
