Pilates class size: how many people per reformer class works
The short answer
Equipment pilates classes range from small groups of 2 to 4 up to larger reformer classes, and the real limit is the smallest of three numbers: machines available, people one teacher can watch safely, and the level of the group. Bigger classes raise revenue per hour, but only work with members who already know the work.
Equipment pilates classes usually run from small groups of 2 to 4 people up to larger reformer classes. The right number for your studio is the smallest of three limits: free machines at that hour, people one teacher can watch safely, and the level of the group. After that, the revenue per hour tells you whether the price works.
What decides how many people fit in a class?
Three limits decide capacity. The smallest one wins.
- Machines. A reformer class cannot have more people than reformers. In circuit classes with a Cadillac, Chair and Barrel, count only the equipment that suits that class.
- Teacher attention. The teacher has to see everyone, cue form and change springs. New members take more of that time each.
- Group level. Experienced members follow the sequence with few corrections. Beginners, prenatal clients and people returning from injury need something close to a private session inside the group.
If you have 8 reformers but a teacher can guide 4 beginners well, the beginner class has 4 spots. The advanced class may have 8.
How many people per teacher works in practice?
There is no single number that fits every studio. A practical reference:
| Class type | People per teacher | Notes |
|---|---|---|
| Beginners on equipment | 2 to 4 | More time on springs and form |
| Small group mixed level | 3 to 5 | Common in boutique studios |
| Reformer flow, experienced | 6 to 12 | Known sequence, fewer corrections |
| Mat pilates | 8 to 20 | Depends on the room |
| Rehab or special needs | 1 to 2 | Close to a private session |
Before you set capacity, check your liability insurance and any guidance from the body that certified your teachers. Some insurers ask about class ratios.
How much does each class size earn per hour?
This is why so many studios want bigger classes. An example with an average of CA$35 per class and a teacher paid CA$60 per class taught, regardless of numbers:
| People in class | Revenue per hour | Teacher cost | Left for the studio |
|---|---|---|---|
| 2 | CA$70 | CA$60 | CA$10 |
| 3 | CA$105 | CA$60 | CA$45 |
| 4 | CA$140 | CA$60 | CA$80 |
| 6 | CA$210 | CA$60 | CA$150 |
The figures are illustrative. Going from 2 to 4 people multiplies what is left for rent and everything else by eight. That is why a class that keeps running at 2 of 4 spots hurts so much.
The logic has a ceiling. If members feel like a number, they do not renew. And the members who pay more precisely because classes are small are the first to leave.
How do you choose between smaller and bigger classes?
A few questions help:
- What did you promise? If your website says “no more than 4 per class”, that is your capacity. Changing it later breaks a promise.
- Who are your members? Older adults, rehab clients and beginners need smaller groups.
- How many machines do you have? With 4 reformers, the question is already answered.
- What is your occupancy today? If 6-person classes run with 3, raising capacity solves nothing. Demand is the issue, not size.
A common answer is different capacities per class type: beginner classes with 3 or 4 spots, regular classes with more, and an advanced flow with the most spots at a slightly lower price per class.
Can you mix levels in the same class?
Yes, with care. Mixed classes work when:
- the group is small,
- the teacher plans two versions of each exercise,
- new members first take a few foundation classes,
- nobody needs constant one-to-one attention.
What does not work is putting a beginner alone in an advanced class because it was the only open spot. They feel lost and everyone else feels the class slow down. If it keeps happening, add a regular beginner class.
How do you control capacity without schedule mistakes?
The usual mistakes are predictable: a make-up squeezed into a full class, two teachers booking the same room at the same time, or someone reserving a reformer that is out for repair.
To avoid them:
- set capacity on each class type, not from memory,
- let the system refuse bookings above the limit,
- keep a calendar per room so nobody books the same space twice,
- lower capacity when a machine is out for maintenance.
More on this in stop double booking rooms and reformers.
When should you review your class sizes?
Capacity is not a decision you make once. Look at it again when something changes: a new teacher joins, you buy or retire a machine, a class keeps running with a waitlist, or a class keeps running half empty. A quick review every few months, class by class, keeps sizes matched to real demand.
How elastudio helps with class capacity
In elastudio each class has its own capacity, and members’ credits count down on their own with every booking, on the Free plan. From Starter, every room has its own calendar, and a room that is taken refuses a second booking. On Growth, you draw the room once with each reformer in place, and members pick their machine on the map when they book. See how it fits pilates studios.
Set capacity per class type
Write down how many machines you have, how many people each teacher guides well and which classes are for beginners. With those three numbers, every class type gets a clear capacity. Compare plans on the pricing page and see everything included in features. Questions are welcome at support@elastudio.app.
Questions people ask
What is a good class size for reformer pilates?
There is no single standard. Small group studios often work with 2 to 4 people per teacher, while larger reformer studios run bigger classes with experienced members and a well-known sequence.
Can beginners and advanced members share a class?
They can, if the group is small and the teacher plans options for each exercise. Beginners usually do better with their own classes for the first few weeks.
Does a bigger class always make more money?
It makes more revenue per hour, but it can cost members. If attention drops, people who chose you for small groups start looking elsewhere.
Do insurers care about class size?
Some liability insurers ask about ratios and teacher qualifications. Check your policy and ask your broker before raising capacity.
