What calculation is used to determine the capacity of a given egress component?

The capacity of an egress component comes from translating the available clear width into how many people can pass, using a width-per-person value. The capacity factor is defined as how much width each person requires. Since more width per person means fewer people occupying the space, you divide the total clear width by that width-per-person factor to get the number of occupants that can use the component. For example, if you have 4 feet of clear width and the capacity factor is 0.5 feet per person, the capacity is 4 ÷ 0.5 = 8 people. Using division reflects the idea that increasing the width-per-person requirement reduces capacity.
