The principal doorway is to be 140½ Aṅgulas high, other medium and good doors are 120 and 130 fingers high. A door 180 fingers in height is the best for ventilation. 110, 116, 100, 90, and 80 fingers are the other prescribed heights of doors. Doors of other heights than these are not good. There should be no obstruction in front of the doorway. It is to be carefully avoided in every case.—22-25.
