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.

What's My Why: Official Cindy Tyzo
June 8, 2026
Cindy Tyzo, West Bloomfield
Tyzo is one of what surely are only a handful of officials who have been registered for two MHSAA-sponsored sports since their first seasons as part of the championship lineup. She's is completing her 33rd year overall after first registering for the inaugural season of competitive cheer in 1993-94, and she also officiated the first season of MHSAA field hockey this past fall.
Tyzo also just completed her eighth season officiating girls lacrosse.
I love officiating because I love working with the young people and providing the opportunity for them to do the sport that they love. Because without officials, there's not game.
“What’s My Why” is a weekly feature telling the stories of MHSAA-registered officials in their own words. If you’re an MHSAA official and would like to share your reason why, please submit a 15 to 45-second video, taken horizontally, to director of officials Sam Davis at [email protected].
