for each additional 750 mm 30 inches (or fraction
thereof) of door height.

heavy, and high-frequency doors on an individual
basis.

is for 44 mm1 3/4 inch doors up to 915 mm 3 feet
wide and with up to 20 mm 3/4 inch trim projection,
and covers the majority of openings. For other
doors, determine hinge width in accordance with:
Twice the door thickness plus trim projection, minus
13 mm 1/2 inch, or 2(t+p)-1/2. If answer falls
between regular hinge sizes, use nearest larger
size. Formula is for hinges set back 6 mm 1/4 inch
from edge of door.
