I don’t know of any specifics, but I believe AFAA describes it as the amount of space required for each participant to move safely through the class without interferring with another participant, having their own personal safety being infringed upon and where any equipment used will not be in the way of other participants. Depending on the type of classes you’re offering, the max number may be different for each class.
Hello Maggie Barclay,
The ACE Group Fitness Instructor Manual says, “Sufficient space for each participant to move comfortably as appropriate to the needs of the specific class.”
I would estimate the person’s height plus three feet for body exercises alone.
Jump roping needs the space of the person holding their rope folded in half in one hand, and spin around.
Each class will obviously be different.
I hope this helps you.

According ACSMs Health Fitness Facility Standards & Guidelines 50sf per person is recommended. That recommendation was made for “aerobic dance” and allowed participants to move 8 steps forward, back, right and left. Based on your cardio requirement 50sf would be safe, but you could probably go to 40sf based on the movement style and the experience of the participants. Don’t forget to account for space in the room that might be taken up by equipment that is stored (balls, steps, mats, etc) or “dead space” (counted in the sf but not an adequate space for a particpant to us). Best of luck!
