Write down the exact dimensions of the frame. Bring these measurements to a hardware store or a home center, and have the new pane cut smaller than the frame's opening. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Place the new pane into the frame and press it in place with your hand.
