Code and safety
This is only a planning estimate. Venue capacity can be governed by exits, fire code, seating layout, accessibility, staff areas and local rules.
Example
With 1,200 square feet, 15 square feet per person and a 20% circulation buffer, usable area is 960 square feet and estimated capacity is 64 people.
How to use the result
Use the estimate early in planning to compare layouts. Then confirm the final capacity with the venue, local requirements and the actual seating or standing arrangement.
Common mistakes
Do not use total building area if parts of the space are taken by stages, bars, storage, staff areas, aisles or exits.
Limitations
This is not an official occupancy rating and should not override fire, safety, accessibility or licensing requirements.
