Shortest width that 2 players can squeeze thru?

Anybody know the shortest width a hallway floor can have, and yet be wide enough for 2 players to pass each other? wouldn’t it be 64 units?

smallest for 1 person x2 +1-2 inch for safety

I assume he wants that in units. You aren’t telling us which game, which doesn’t help since TF2 and L4D have different sized player collision hulls to hl2. In Hl2, 72 units would be a safe bet.

The width of the player hull is 33x33, so 66x66 would be enough for two players, but you might wanna go with what metallics said.

Praise be to Wiki.
