How to use it
- 01
Choose what you know
Start from the number of people to get a room size, or from a room's floor area to get its capacity.
- 02
Pick a layout
Each layout starts with a typical space allowance per person, which you can change to match your furniture and venue.
- 03
Compare and confirm
See the result for every layout side by side, then confirm with the venue, whose safety rules set the real limit.
Before you book the room
These are rules of thumb
Space per person varies with furniture, aisles, and the venue. Use the result to shortlist rooms, then confirm capacity with the venue.
The venue's limit always wins
Every room has a maximum occupancy set by local fire and safety rules. Never plan above it, whatever a calculator says.
Leave space for more than people
Screens, a presenter area, catering tables, and storage all take floor space. Add it on top, or raise the space per person.
Small meetings need privacy more than space
For one-to-one meetings at an event, a quiet room you can book matters more than its size. A crowded stand is the wrong place for a sensitive conversation.

The room's floor area divided by the space allowed per person, rounded down to whole people. Check it against the venue's maximum occupancy, which always takes priority.
