1. Trim
Trim is priced and sold by the linear foot. Base
trim is commonly 3-1/4" wide, and door and
window trim is 2-1/4" wide, but other widths are
available. Base trim is equal to the perimeter of
the room minus the width of the doors.
Door and window trim is commonly called
casing. When trim is installed, angled cuts
called miters are made at the corners of doors
and windows; therefore, the trim will need to be
longer. Door trim is not installed along the
bottom, so there are three pieces – two sides
and one top. Each side trim is equal to the
height of the door plus the width of the casing.
The top piece is equal to the width of the door
plus two times the width of the casing.
The top and bottom casing for a window would
be the width of the window plus two times the
width of the trim. The side casing would be the
height of the window plus two times the width
of the trim.
There is one 32" x 6' 8" door; one 24" x 6' 8"
door; and two windows, each 24" wide x 48"
tall.
