How many seats a room takes depends on the layout (tables, desks or rows of chairs), the width of the aisles and the gap between rows. Here are seven rooms an AI counted in earlier articles, with the tool it calls over MCP (suggest_arrangement). The tool keeps clear of walls, columns and doors, and checks the aisles and doors once it has set out the room.

1. A restaurant's tables (12 × 6.6 m = 79.2 m², two columns)

  • Tables of four keep 40 seats from 0.9 m aisles to 1.2 m, and drop to 28 at 1.5 m.

  • In the same training room, theatre rows (102) take 1.7 times classroom (60), and over four times islands (24).

3. A hall for a talk (a meeting room of 22 × 18 m)

  • The gap between rows and the number of seats allowed between aisles are set by the local fire prevention ordinance (the base seat numbers of Article 35 of the model Fire Prevention Ordinance). In this room, closer rows add no row, and the extra aisles take seats away.

4. Banquet halls and gyms

  • With a space 1.9 m square for each cardboard bed, the gym takes 78 people with 1.2 m aisles and 91 with 1.0 m: about half the 182 it holds at 3.5 m² per person.

7. How to ask an AI

How many seats does this room (as drawn) take in classroom style, theatre rows and islands? Compare aisles of 0.9 m and 1.2 m, and keep the doors clear.

8. What this does not check

  • The seats are counted with the layout tool's sizes (tables, desks, chairs) and gaps. Give your own furniture's sizes and gaps.
  • For the occupant capacity and the fire prevention manager, see how the fire code counts occupants.
