How Long Should Window Valances Be

For example a fuller pinch pleat valance should have a minimum drop of 8 inches.

How long should window valances be. If the valance is to be hung 9 feet or higher above the floor you can suitably increase the drop to up to 28 inches. The header style and the valance shape are other factors that can affect the drop length. A standard valance should have a drop of about 18 to 24 inches. Then decide how long your valance will be.

Starting at the top of the window opening or curtain rod the valance should be between about 12 and 18 inches deep in most cases around 15 inches. There is not an exact ratio to use for valance length but a good start is around one sixth to one quarter the height of the window. Anything less than 16 inches is too short and only works in situations where the role of the valance is to be a mere accent or when the ceiling or the window itself is too low. A 60 inch tall window then would call for a 16 inch deep valance while a 48 inch window calls for a valance about 13 inches deep.

You can make it as long as you like so long as it fits your window. For example if the window is 50 inches wide the valance should be about 100 to 150 inches wide when laid flat. Measure the width of your window opening or curtain rods and make a note. You may be able to make a 16 or 17 inch drop valance work in some cases but anything less than that may be too short.
