Be the Referee: Basketball Measurements

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.

Performance of the Week: Goodrich's Kayla Hairston
March 26, 2026
Kayla Hairston ♦ Goodrich
Senior ♦ Basketball
The Martians’ senior guard almost couldn’t miss during her team’s Division 2 championship victory over Tecumseh on Saturday, making 7 of 8 shots from the floor including 4 of 5 from 3-point range, and all three of her free throws to score a team-high 21 points as Goodrich prevailed 55-44. She scored 11 of those points during the fourth quarter as the Martians not only defeated the 2025 champion at Breslin Center, but finished a perfect season at 29-0 – becoming the first team to reach 29 wins in MHSAA girls basketball history.
Hairston also had a team-high 17 points in a 47-41 Semifinal win over Grand Rapids South Christian and finished this season averaging 14.5 points per game and topping 60 3-pointers. A returning all-stater this winter, Hairston was a four-year varsity player who as a freshman saw time in Goodrich’s 2023 Semifinal. She also runs track and made the MHSAA Finals as part of the 800 relay last season. Hairston will continue her basketball career at Northwood University.
