Use the SMALLEST of these 3 measurements to order the window.

HEIGHT: Measure from the (H1) High Point of the sill of your window (the surface closest to the inside of window) to the (H2) top of the window opening. Make 2 measurements. One at the left side of the window and one at the right side of the window.

Use the SMALLEST of these 2 height measurements to order the window! Take these 2 dimensions, for each window you are ordering to your dealer. He will supply you with the correct size windows for your openings.
Note: Window Rough Opening DEPTH Dimensions Needed
(Ignore all pulleys and parting strips when measuring for depth dimension as they will be removed replacement window installation.) There must be at least 3 1/4" of opening depth between the inside (D1) Window trim and the outside (D2) Blind Stop Strip.

This much area is needed to accept the depth of the replacement window!

(If this much depth are is not available the outside Blind Stop Strip will have to be removed and replaced further toward the outside of the opening.)
