how do I measure for wood replacement windows?

1. The most accurate way is to remove the interior trim from the window so you can measure the rough opening of the framing lumber.


2. measure from the window sill to the top of the frame. that will determine the height.now, here's where it may get tricky,measure from side to side the flat jam section,disregard the stops that separate window from window these will be removed when the new window is inserted.if they are plastic or metal look for screws that anchor them, if they are wood start at the top or bottom and pry out with a putty knife or old screw driver. now you should have 4 smooth surfaces to insert new window
