Set each class’s size by the number of students a coach can teach well, then price it so the class makes money at about 70 to 80% full, not only when it’s packed. Cap bookings so classes never go over, give cancelled spots to makeups and casuals, and catch coach and venue clashes before they happen. A full, well-run class earns more over a year than an overfull one that loses families.
Thursday, 4.30pm. The coach arrives to find eleven kids for a class meant to take eight. Two are makeups booked into spots that weren’t really free, one was enrolled twice by mistake, and another group has the court next door for the same hour, so there’s nowhere to split them. Nobody gets a good lesson. By Sunday, a parent has emailed asking for a refund.
Key takeaways
- Set class size by what one coach can teach well, not by how many fit in the room.
- Work out the break-even number for each class. You should be making money before the class is full.
- Hard caps on bookings protect coaching quality and your reputation.
- Cancelled spots are money. Fill them with makeups, casuals and trials.
- Double-booked coaches and courts cost you twice: the lost lesson and the lost trust.
Why does class size matter so much?
Class size moves both sides of your business at once. More students in a class means more revenue for the same coach and court. But past a point, each student gets less attention, progress slows and parents notice. That’s when families quietly don’t come back next term.
The goal isn’t the biggest class you can run. It’s the size where the class pays well and students still get enough coaching to keep improving and keep coming back. For more on that, see how to keep students longer.
How do you pick the right size?
Start with the coaching, not the maths. Ask your coaches how many students they can teach well at each level, then check the space and equipment.
| Class type | Typical size per coach | Why |
|---|---|---|
| Young beginners (under 7) | 4 to 6 | Need lots of hands-on help and have short attention spans |
| Juniors and intermediate | 6 to 8 | Can run drills in pairs or small groups |
| Advanced or squad | 6 to 10 | More independent, often need space more than coach time |
| Adult social or fitness | 8 to 16 | Less individual correction, more about the session |
| Private and semi-private | 1 to 3 | Priced for close attention |
These are starting points. A swim lesson in deep water needs a smaller group than a dance class in a big studio, and your sport’s safety guidelines may set a limit of their own.
How many students do you need to break even?
Work out what one session of the class costs to run: coach pay, court or room hire, and a share of overheads like software, insurance and admin. Then divide by what each student pays per session.
Say a class costs $90 to run and each student pays $20 a session. You break even at 4.5 students, so five. With a cap of eight, every student past five is mostly profit. A full class earns $160 against $90 in costs.
If break-even is close to your cap, the class is fragile. One or two dropouts and you’re running it at a loss. Either the price is too low or the class is too small. See how to price coaching classes in Australia and how to pay your coaches.
Aim for classes that make money at around 70 to 80% full. That gives you room for a few absences without losing money that week.
Why set a hard cap on bookings?
It’s tempting to squeeze in one more. One more student is $20 more this week. But overfull classes cost you in ways that don’t show up straight away:
- Coaches can’t give everyone attention, so progress slows
- Parents watching from the side see a crowded class and wonder what they’re paying for
- Your best coaches get frustrated and start looking elsewhere
- In some sports, the safety risk goes up
A hard cap on every date, for every type of booking, takes the decision out of your hands. When the class is full, it’s full. It also makes spots feel more valuable, which helps when it’s time to get families to re-enrol.
What should you do with cancelled spots?
A spot left empty by a cancellation is revenue you’d already planned on, sitting idle. Fill it with:
- Makeups. Families who missed a class get a spot, which keeps them happy and uses capacity you already have. See make-up class policy: template and examples.
- Casual bookings. Someone who can’t commit to a whole term pays a casual rate for one session. See should you offer casual bookings in a term-based program?
- Trials. A free spot in the right class is the best place to put a new family. See how to run a free trial class that converts.
The catch is doing it without overbooking. If a spot opens up when someone cancels and closes again once it’s filled, you get the revenue without the chaos.
How much do double bookings cost you?
A coach booked for two classes at once, or two groups sent to the same court, is more than an awkward afternoon. You lose the lesson, usually refund or credit it, and lose some trust with every family who turned up. For a family who was already unsure, one clash can be the reason they leave.
Most clashes come from small changes. A coach swaps a shift, a class moves courts for a week, or a holiday program gets added on top of the regular timetable. The fix is to catch them when the booking is made, not on the day. A warning before you save is far cheaper than an apology after.
Duplicate bookings are the quieter version. The same student enrolled twice takes a spot someone else could have paid for.
When should you split or merge classes?
Review class sizes every term.
- Split a class when it’s been full with a waitlist for a term or more and you have a coach and space for a second session. Two classes of six often earn more than one class of eight with a waitlist.
- Merge classes when two at the same level are both under break-even. One full class beats two half-empty ones.
- Move the time if a class is always short. The class might be fine and the slot wrong.
Common mistakes with class sizes
- Setting the cap by the room, not the coach. Space is rarely the real limit.
- Pricing so a class only pays when it’s full. Every absence then costs you.
- Going over the cap “just this once”. It’s never once, and families notice.
- Leaving cancelled spots empty. That’s income you’d already counted on.
- Finding clashes on the day. By then the damage is done.
How does Outcoach help with class capacity?
Outcoach keeps your classes full, but never over-full.
- Booking limits for each date, so no class goes over its cap
- Spots open up automatically for makeups when someone cancels
- Duplicate protection, so the same student can’t be booked twice
- Warnings before you double-book a coach or a venue
- A month view where every class shows its capacity and status at a glance

Frequently asked questions
Four to six for young beginners and six to eight for most junior classes. Adjust for your sport, space and safety guidelines.
Add up coach pay, venue cost and a share of overheads for one session, then divide by what each student pays per session.
No. Overfull classes hurt coaching quality and make families question the value. Offer makeups in classes with free spots instead.
When it’s been full with a waitlist for a term or more and you have a coach and space for a second session.
Use a booking system that warns you when a coach or venue is already booked at that time, before you save the change.
