Currently, the player capsule is exactly 2 meters tall.
The Standard US door height in homes is 6ft 8in tall, or 2.032m.
This means that the amount of room for a player to fit through a standard height door is very small, and often enough is too small for you to fit through. You will often bump your "head" on the door, or get stuck.
I suggest lowering the default collider height to something more reasonable, such as the average US height, or a bit higher, such as 1.7m-1.8m.
