What are the player dimensions in a map?
The unit scale in CoD seems to be about 1 unit : 1 inch. (roughly)

1 unit = 1 inch in CoD.
1 foot = 12 units in CoD.

Players are 72 units or 6 feet high.
Players are 32 units wide.

Stairs in CoD are 8-12 units high.
Doors are 52x96 units in CoD (dawnville). Door thickness is 4-6 units.

Ladder rungs on a ladder that is in Dawnville are 24 units appart.It looks kind of silly. In real life this would be more like 12 units.

Outter walls are 8 units thick. I made inner walls 6.

Sidewalks 64 units wide and 8 units high

Height to ceiling is normally 128, but then again it all depends if its a anormal room, warehouse or what your creating.

Player Height Clearance =< 71 units
Player Crouch Clearance =< 51 units
Player Prone Clearance =< 31 units
Player Max Jump =< 39 units
Player Width Clearance =< 31 units

The unit scale o­n this game seems to be about 1 unit : 1 inch. Most of the models I look best when scaled to 75%.

*To change the size of a model, add the modelscale key with a decimal value - 0.75 for 75% - in the entity box for the model.
