Egress Door Clear Opening

Hi All,

If asked to size an egress door by occupancy count but the question does not specify whether they want the clear opening or the actual door size. Minimums being 32" and 36". Should we give the clear opening or door size?

Hi @clent - I’d say that if a question is asking you specifically to size a door, they’re talking about the door leaf size, not the clear opening. I think a question would need to specifically use the term ‘clear opening’ if that’s what the question was asking about.

Thanks @coachchrishopstock i actually just came across a black spectacles quiz that contradicts that thought. I tend to agree with you but I have come across similar wording on NCARB and provided the door width as you suggest.

This is part of the paid subscription to black spectacles so I will reframe from posting the whole question but as you can see from the math the correct answer was in fact the clear opening:

Per the International Building Code (IBC) and assuming all occupants will egress equally from all doors, what is the minimum required egress door width for the building? Round to the nearest inch

185 occupants x 0.2 in/occupant = 37 inches
