Note the result as the finished width for flat and pleated valances or the installed width for valances you gather on inside mounted rods such as tension rods.

To ensure your window valance is hung correctly include the rod pocket in the length. Measure the width of the window opening from the inside left of the frame to the inside right. If you are not using curtains measure the width of the window and add 3 inches. For treatments and valances mounted inside the window frame measure from side to side inside the window frame.

To ensure the window treatment does not extend out into the room measure the depth. Using a 2 to 2 1 2 times fullness calculation that means that the valance when laid flat needs to be between 84 and 106 inches wide. For unlined valances or valances made with light weight fabrics you ll need to go up to 3 to 3 1 2 times fullness. That means that the valance should cover a total width of about 42 to 44 inches once gathered.
