Entity touches the floor right? In grid 8 the entity is 7 units tall and 4 units wide. Make your doors around 9 to 10 units tall. If the doors are too big they will look gigantic when a player stands next to them, if they're too small they will look like they're made for midgets.
Player model in real world scale is around 6 feet tall, info_player_deathmatch entity is around 5'5.
