How to choose a class size
The number of students in a class changes how much each of them learns. With too many, the instructor cannot watch everyone, give useful feedback or keep the room safe. With too few, the class can feel flat, and it may not cover its own costs. A clear limit for each class helps you find the right balance, and it shows families that you take their safety and progress seriously. This guide explains how to choose that limit, whether you teach martial arts, yoga, dance or small group fitness.
Start with your space
The first limit is the room itself. Students need enough space to move, stretch, fall and practise without bumping into each other or the walls. Measure the area you actually use for teaching, leaving out the space taken up by benches, bags and doorways, and then think about how much room one student needs for the activity.
That amount varies a great deal. A yoga student needs a mat and a little space around it, so you can count the mats that fit comfortably and stop there. A karate or judo class that practises throws, kicks or sparring needs far more room per person, and a dance class that travels across the floor needs space to move as a group. A small room means a small class, however popular the session is.
Think about age and experience
Young children and beginners need much more of the instructor's attention than experienced students. A group of five-year-olds needs constant guidance to stay on task and to stay safe, and adult beginners also need time to learn the basics and have their technique corrected. Experienced students can often work in pairs or small groups with less supervision, which means their class can safely be larger.
As a rule of thumb, set lower limits for children's classes and beginners' classes, and higher limits for experienced adult classes. If you mix ages or levels in one class, set the limit for the group that needs the most attention rather than the one that needs the least.
Count your instructors
One instructor can only watch so many people at once. If you add a second instructor or an assistant, you can usually raise the limit, because one person can lead the class while the other corrects and helps. Be honest with yourself about this, though, because an assistant who is still learning does not double the number of students you can teach well.
If you work alone, as many private trainers do, plan your limits around what you can see and hear from one spot in the room. A small group personal training session of four to six people lets you check everyone's form on every exercise, which is often the reason people choose a small group in the first place. Write down the number you choose for each class, along with the reason, so that you can apply the same thinking when you add new classes.
Match the limit to the activity
Classes that carry more risk need more space and closer supervision. A martial arts class that practises throws or sparring, a circuit class with heavy equipment and a swimming lesson all need a lower limit than a class that practises forms, stretching or a dance routine. Think about what could go wrong in each class and how quickly you could step in if it did.
The same class can need different limits at different times. A Saturday class that spars once a month may need a lower limit on that day than on the other Saturdays. If that makes the timetable complicated, it is usually simpler to use the lower number all the time.
Keep to the limit
It is tempting to let one more student in just this once, especially when a parent asks nicely or a friend wants to try a class. Once you do, however, the limit stops meaning anything, and the next family will expect the same. Keeping to the number you set lets families trust that every class is run safely and in the same way.
A firm limit also helps you plan your timetable. If a class is always full, that is a clear sign that a second session would be welcome, and the number of families asking about a place is good evidence for adding one.
Review after a few weeks
Once a class has run for a few weeks, look at how it feels in practice. If the room is crowded, students are waiting too long for their turn, or you cannot get round everyone, lower the limit. If the class always has plenty of space and still runs well, you may be able to raise the limit a little, or move the class to a time that suits more people.
Talk to your instructors and students as well. They will often notice problems, such as not enough room to practise safely or too little individual feedback, before you see them in the numbers.
How VPage helps
Every class in VPage has a capacity, which you set when you create the class and can change later. When a class is full, students cannot join it, and when someone cancels, the seat is free again straight away. The calendar shows how many seats are left in each class, so families can see at a glance where there is room. See all features.
