Event planning
Calculating table and chair counts for a ballroom — a method that survives contact with the floor
Area per seat for each layout, how to deduct circulation and stage, and why the number on paper is usually higher than reality.

Start from usable area, not room area
The room area quoted in a brochure is gross area. The area you can actually place tables on is always less — deduct columns, entrances, the space in front of the stage, service routes, and the arc of any inward-swinging doors.
The least error-prone method is to draw the actual layout and measure what remains after those deductions, rather than dividing gross room area by area-per-seat, which always overstates capacity.
The layout determines area per seat
Each layout consumes a very different area per seat, because round tables need clearance all around, and any layout with food service must allow for staff circulation.
From least to most space-hungry: theatre (chairs only) → classroom (with long tables) → round-table banquet (with service). Switching the same room from theatre to banquet rounds reduces guest capacity substantially.
Deduct stage and dance floor before seating
Stage and dance floor are areas where no table can go, and you must also allow clear space around the stage for access steps and camera positions.
Portable stages adjust across several heights (the models in our catalogue set to 600, 800, and 1,000 mm). The height you choose affects the space needed for steps and the sightline from the back tables — so decide the height before laying out tables.
Service circulation is the most commonly forgotten item
Layouts calculated on paper usually forget that staff carry trays between tables, and that guests must be able to pull chairs out without hitting the table behind.
Circulation that is too tight does not just feel cramped — it lengthens service time across the whole event and raises the risk of spills onto guests. Allow enough for two staff to pass each other on the main routes.
Always dry-run a new layout
Before the first major event in a new layout, set it up once and walk the service routes, pull chairs out and sit in them, and check the sightline from the back table to the stage.
Problems found in a dry run are fixed by moving tables. Problems found during the event cannot be fixed at all — and guests remember them.
