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: Goaltending vs. Basket Interference

MHSAA Marketing & Social Media Coordinator

December 2, 2025

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 – Goaltending vs. Basket Interference - Listen

We’re on the basketball court today to talk about the differences between goaltending and basket interference.

Goaltending occurs when a player touches a shot that is on its downward flight and has a chance to go in.

Basket interference is when a player touches the ball when it is on the rim, or inside the cylinder above it.

An offensive player cannot be called for goaltending but can be called for basket interference.

And once a shot hits the backboard, it is automatically considered to be on a downward flight, even if it is still going up. It’s goaltending by the defense if they touch a shot with a chance to go in that has hit the backboard.
