This guide provides an operating framework, not legal, financial, safety, medical, licensing, or regulatory advice. Adapt it to your business and local requirements.
Set capacity from safety, then comfort
Start from the hard safety limits, the instructor ratio, the room egress, the mat count, the reliable equipment, and only then pull back for comfort. A class that admits more people than one coach can cover properly serves nobody at all. Write the cap for every class size and post it. Staff then never improvise a number mid-shift.
Make late cancellation meaningful
Make a missed spot cost something small. A no-show or a late cancel bumps that member to the back of the next list, and the rule stays friendly rather than punitive. The point is not punishment; it is a freed seat for somebody who genuinely plans to train.
Handle the waitlist transparently
Show members exactly how the list moves. Spots open when somebody cancels, they get notified a set window before class, and they find out how to drop a spot if plans change. A system people understand earns trust, and that trust cuts the angry messages that arrive when a seat never opens.
Open a second option, not an overflow
if a slot fills again and again, add a second time instead of cramming the same hour, because a fresh session keeps coaching quality and catches demand that would otherwise walk away entirely. Read your booking data first. A busy Thursday evening is the clearest clue you have.
Review caps as the roster changes
Review caps every month, because the membership mix shifts, instructors change, and a yoga room tuned for one crowd feels different for the next. A cap that never moves either gives space away or crams the room tight. Neither version helps the people in it.
