  • Standards Compliant door in the USA: 0.965 x 2.08.
  • Measured example (small interior door): 0.6 x 2 (about as small as you can get away with)
  • Measured example (residential front door): 0.8 x 2 (fairly comfortable)
  • Smaller doors are found in older construction.
  • Most public doors are large, residential doors may be smaller.


In order to have extra space to account for imprecise character control and chase camera, and to avoid stalls due to blocked openings, we ought to follow the general rule:

  • 1 meter wide and 2.2 meters tall in-game.


These are the basic heights one should use for stories of floors in architecture:

  • Residential — 3m
  • Commercial office space — 4 to 5m
  • Industrial, warehouses, etc — the sky's the limit
