For corner windows, measure based on your chosen mount style.

Note: Valance depth varies between shade types. Refer to the product page to confirm the minimum depth requirements. The diagram below uses roller shades as an example.

How to Measure Multiple Shades in One Window

How to Measure Bay Window

If each of your windows is self-contained, meaning that trim or wall space separates them, then you measure each window exactly like any other individual window.

You cannot measure your windows in the normal manner if they are all connected. Valance will eventually collide with one another.

• Step 1

Cut out two pieces of cardboard that are 3 1/8 inches (9cm). (This data is for reference only. The depth varies depending on the shade type and the installation of the brackets. Please refer to the images for detailed measurements) These will serve as placeholders to mark the positions of the valance for each shade, ensuring they don't overlap or interfere with each other during the installation and operation of your window coverings.

• Step 2

Position the cardboard pieces so their front edges align at the adjoining corners, then tape them in place as illustrated here.

• Step 3

Using a pencil, lightly mark each end of the cardboard pieces where they form an angle and meet in the middle window. Measure the distance between the marks to determine the width of the middle window.

• Step 4

From the center marks at the corners of the middle window, measure the width of the window to the right and then to the left edge. Be sure to double-check all your measurements, rounding each window's width to the nearest 1/8 inch. (During production, the factory will apply a small deduction of approximately 1/8 inch (3.2 mm) to ensure a safe and proper installation.
