What Is Crowd Density?
Crowd density is the amount of space each person occupies in a crowd. It's usually measured in:- Imperial: square feet per person (sq ft/person)
- Metric: square metres per person (m² /person)
Density Categories Explained

- Used for casual events like open parks, exhibitions, or light foot traffic.
- Typical standing crowd spacing at a concert or busy event.
- Elbows might touch occasionally, but people can still move.

- Common in packed rallies, concert front rows, and parades.

- Extreme crowding - very little room to move or even turn.
- Often considered the maximum safe density before risking crush hazards.
- Only acceptable for short periods and usually with security oversight.
This calculator helps users evaluate crowd limits for indoor or outdoor spaces, ensuring a quick and practical estimate of how many people can fit within a given area measured in metric units.
