Work out crowd density instantly with clear inputs, formula shown and shareable results.
Density is people divided by usable area, and the reciprocal gives the space each person has; the categories follow the standard crowd science thresholds. Crowd risk rises sharply above about four people per square metre because individuals lose the ability to control their own movement, which is how progressive crowd collapse begins.
Density
density = people / usable area in square metres
Space per person
space = usable area / people
density = people / usable area in square metres. Density is people divided by usable area, and the reciprocal gives the space each person has; the categories follow the standard crowd science thresholds.
Crowd risk rises sharply above about four people per square metre because individuals lose the ability to control their own movement, which is how progressive crowd collapse begins.
Enter usable area, number of people. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
