The room holds twelve people. You own eight pasta machines. Your class capacity is eight, unless four people have come to watch someone else roll dough.
The number of seats in a booking system should come from the experience you can deliver, not the maximum number of bodies the room can hold.
Find the real limit
Capacity can be set by floor space, safety requirements, equipment, instructor attention or the number of places at a table. Use the smallest relevant number. If a class uses one instructor for four beginners, adding ten more aprons does not create ten more places.
Work through one session: how many people can participate at once, what does each person need, and how long does help take? Then check any venue or activity-specific requirements that apply to your business. Do not use a generic capacity figure as a substitute for those rules.
A capacity worksheet for one class
For the pasta class, a quick capacity worksheet might read:
| Constraint | Places supported |
|---|---|
| Workstations | 10 |
| Pasta machines | 8 |
| Instructor attention for beginners | 8 |
| Room limit under applicable rules | Check separately |
That makes eight the working capacity only if the room and safety requirements also allow eight. It gives you a reason to change the number if you buy more equipment or add another instructor.
Sell places, not vague interest
Be clear whether someone is reserving one place, a private group session or the whole room. If a customer can book for several people, collect the party size and show the total before they confirm. A booking for “one customer” with six people arriving is an avoidable surprise.
When a class is full, do not quietly accept a ninth booking because someone usually cancels. A full class can have a separate enquiry or waiting list, with wording that says a place is not yet confirmed. Our guide to handling enquiries when you're full covers that distinction.
Leave room for the session around the session
If a class runs from 6pm to 7:30pm, the room may be occupied before and after. Include setup, arrivals, cleanup and any equipment reset in the schedule. Two classes can share a day without sharing the same 15 minutes of washing up.
Tell participants what they need to know before arrival: where to go, when doors open, what to bring, and whether the class needs a minimum number to run. If you may cancel a session below that minimum, state when you'll decide and what happens to payment.
Review capacity after a few sessions. Count how often people waited for equipment or for your help. A class can be technically under its limit and still feel overcrowded. If the eight-place class regularly queues at two machines, lower the cap or change the session design before selling a ninth place.
