How to measure for curtains?

For curtains and drapery, you will need to measure the panel width. If you want your curtains to close and cover the entire window:

• Measure the width of your window.
• Add 12 inches to each side, 24 inches total.
• Take the total number (width plus the number you added to each side) and divide that number by how many drapery panels you want in the window.
• Make sure the number of custom drapery panels you order can cover the entire area you want covered (total width divided by panels). For example, for a 60-inch window with two curtain panels, add 24 inches to 60 inches (window width) and divide by 2 (number of panels) to get 42 inches. The two panels ordered each need to be at least 42 inches wide.

What length curtain or drapery you select will depend on the look you want.

• Valance style draperies can make a window appear taller, and are recommended for outside mounts. Choose a length from 10 to 30 inches.
• For a sill style curtain, make sure the length will end 3/8 inches above the window sill. We recommend sill style draperies for outside mounts, or for windows that have sills that extend past the window opening.
• Cafe style draperies are recommended for both inside mount or outside mount, and are most often used in kitchens. For a cafe style, choose a length that will hang 6 inches below the bottom of the window, or 3/8 inches above the window sill. It is best to place the drapery hardware around the middle of the window for this style.
• Apron styles are recommended for outside mounted windows, and should drape about 4 to 6 inches below your window sill or the bottom of your window.
• For floor style drapery, the length should stop 3/8 inches above your floor. We recommend this style for any drapery that might be operated frequently, and is most commonly used with outside mount.

The sweep, brushing or cuff length drapery style is most often used for outside mount windows, and is useful when your room requires exact mounting, such as a ceiling mount that drapes to the floor.

If you know the width is 10.5, add 3-4 inches on each side for a hem. Add 2-3 inches on the top for a rod, and another 3-4 inches on the bottom for a hem.
