Window Measuring Guide

How to measure


First, decide if you would an Inside or Outside Mount:

An inside mounted shade is mounted within the window frame. An inside mount allows you to cover your window, without hiding the window molding. You must have at least 1" on inside frame for brackets.

If you choose Inside Mount:
Measure the width (left to right) of the window at the top, middle and bottom. Use the smallest or shortest of the three measurements for the width.
Measure the length (top to bottom) of the window from inside of frame to the sill. Measure both sides and the center. Use the longest measurement for the height.
Round each measurement down to the nearest 1/8".

Outside mounted shades are mounted on a wall or molding. This is a great way to make a window look larger, or make two uneven windows look the same size. It is also an option when the depth of the frame does not allow for proper inside mounting.

If you choose Outside Mount:
Measure the width and length of the area to be covered. The shade should overlap the window opening by a minimum of 2". If there is a molding around the window, be sure to measure from outside edge to outside edge.
If you do not have a window sill, please add 1 ½" to the height measurement.
Round each measurement down to the nearest 1/8".


Measure the width of the area to be covered, including window molding when applicable. For a full look, order a width that is 2 ½" times (or more, depending on desired effect) the measured window width.

Measure the length of the window, deciding where you will be placing the rod and where you would like the drape to fall. For a pooled effect, add 6-8" to the length.

Our rod pocket and tab top panels are measured from the top of the rod pocket and tab top to the bottom of the hem.


It's very important to use a metal tape measure only — yard sticks or cloth tape measures are not sufficiently accurate.

Be sure to measure every window to ensure you are purchasing the right size.
