Window head heights: align at 6'8" or 7'0" within a room
ROT/EXT-WINDOW-HEAD-HEIGHTDescription
All windows on the same wall (and ideally throughout a room) should align at a consistent head height — typically 6'8" (80 in, matching a standard door head) or 7'0" (84 in). Misaligned heads read as architecturally sloppy. Where the room has 9 ft+ ceilings, consider raising heads to 7'4" or 7'8" to leave a smaller header band above and a more proportional reveal.
Why this exists
Window head alignment is the single most important geometric rule for the exterior elevation. Architects who consistently miss it produce elevations that look 'home-builder' rather than designed.
