Officiate Michigan Day 2026 will welcome 2,000 MHSAA-registered game officials to Grand Rapids on July 25 – and registration is available now for this historic gathering expected to draw participants from all over the state.
Doors open at 7:30 a.m., with the first session at 9 a.m. at DeVos Place. The day-long event will feature dynamic speakers and presenters providing knowledge in several sports and all levels including collegiate and professional. We will be highlighting several of those speakers over the next many weeks on MHSAA.com and social media as part of the lead-up to the event.
Cost is $45 if officials register by the end of June, and $50 beginning July 1. More information is on the way; keep posted at MHSAA.com/OMD.
This will be the third Officiate Michigan Day, joining events in 2013 and 2018.
OMD will accompany the annual National Association of Sports Officials (NASO) Summit that will take place July 26-28, also at DeVos Place.
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.
