The window jamb is the vertical member, usually wood, on each side of a door or window frame. The jamb is always at a right angle to the door or window. The window jamb fits into the 2-by-4 wall studs that secure the unit in place. The window jamb fits into a 4 9/16-inch or a 6 9/16-inch opening. The wall studs are 2-by-4 or 2-by-6 framing. The do-it-yourself handyman can accomplish this measurement for an Andersen window with just a pen, paper and a tape measure.

Step 2

Open the window so that you can see the entire side of the interior window jamb.

Step 3

Measure the window jamb's depth. This will be from where the exterior brick mold is attached to the window across to where the interior window trim attaches to the jamb. This is normally 4 9/16 or 6 9/16 inches deep. The brick mold is the exterior window trim that attaches to the window jamb. Write down all the jamb's dimensions, and not just the depth, in inches.
