I am measuring for replacement windows and the internet is
contradictory on this, I have the interior trim off and I am going to
measure the outside edge of the Jambs (the exposed wooden box the
window sits in) side to side and top to bottom. is this right? Thanks
Yes, in 3 different places.
Width: top, middle and bottom
Height: left, middle and right
Use your highest measurement, also make sure you make your vertical
measurement from directly inside the sill. Best device to use is a
carpenters rule with the 8" slide on one end. Standard tapes can cause you
to be off sometimes up to 1/4". The manufacturers take your measurements and
subract either 1/8, 1/4 or even 1/2 so you need to be as close as possible.
Width: (top)2, (middle)2 1/8, (bottom)2 1/4
Hieght: (left side)Q 1/8, (middle)Q 1/4, (right side)Q 1/8
Your replacement window would be 32 1/4 x 51 1/4
Measure outside too. My house the outside was smaller than inside and they
could not get windows all the way in so I lost half my window sill. May
have been because of siding but I would check for sure and you want to use
the smallest measurement measure middle too!
