Hey, so I know if you go to http://developer.valvesoftware.com/wiki/TF2/Team_Fortress_2_Mapper's_Reference they give you the default sizes of some stuff... but I thought it would be handy to have average sizes of things they missed... like props, door ways, ceilings. Here are a few I found (units in Hammer):
Average Door - small: 128 wide x 128 tall x 16 deep
Average Door - large: 192 wide x 128 tall x 16 deep
Average Room height: 208 units
I will continue to add to this list if you think of more...
