Measuring for Window Treatments

Hi, I’m Beth from aj MOSS and I’m here today to show you how to measure your windows for window treatments. [beth 00:01]

First you’ll need a measuring tape, a notebook, and a pen. [tools 00:09]

You should measure each window you wish to dress. Don’t assume that your windows are all the same size, even if they appear to be identical.

It’s a good idea to make a sketch of the windows you plan to measure. This will help you to keep track of different sized windows and help reduce confusion. [sketch 00:22]

First you must decide whether you want your window treatments to hang on the inside of the window frame or the outside of the window frame. Inside mounting is a good idea if you have attractive molding around your window. Outside mounting is a good idea if your windows are not square or if you have molding around your window that is not particularly attractive. An outside mount can also help a small window to appear larger and it also offers superior privacy, blackout, and insulation properties.If you are measuring for an inside mount, first measure the width of the window.[width 00:56]

Measure horizontally from the inside edge of one side of the window to the other side. Measure in three places and use the narrowest width.[3 widths 1:05] Try to be as exact as possible, rounding to the nearest 1/8″.

Now measure the height of the window.[height 1:12] Measure vertically from the inside edge of the top of the window to the inside edge of the bottom of the window. Measure in three places, and use the longest length.[3 heights 1:20] Again, be as exact as possible, rounding to the nearest 1/8″.

Write down the exact window opening size. Most manufacturers will automatically deduct approximately 3/8″ to 1/2″ on inside mounts so your products will operate properly and not rub against your window frame.

If you are measuring for an outside mount, first measure the width of the window.[width 1:42]

Measure the horizontal difference between the outside edges of the window molding. Measure in three places, and use the widest width.[3 widths 1:55]

If you want an unobstructed view when the curtains are open, add 8″ to your measurement. Now measure the height of the window.[height 1:58]

Outside mounts hang above the window opening, either on the wood frame or above the wood frame. Leave room for the mounting brackets which can be 1″ to 3″ tall.[mounting brackets 2:09]

For outside mounts, specify the exact width and exact height you want the treatment to be. Manufacturers will make your product the exact size you specify and will not take any deductions.

I’d like to close by making a few comments about some specific types of window treatments. In general, roman shades and blinds should be measured just as I’ve instructed whether they are to be mounted on the inside or outside of the window. However, you should call the manufacturer after you’ve made your preliminary measurements and before you place your order because roman shades and blinds often require measurements adjustments which differ from design to design.

Valances should be one and a half to three times the measure width to allow for fullness. Ready made valances are typically between 12 to 22 inches tall and usually cover the top 25% of a window.

Tiers, also referred to as cafes, generally cover the bottom half of the window and rest on the sill. Like valances, tiers should be one and a half to three times the measured width to allow for fullness.

Drapes and sheers should also be one and a half to three times the measured width to provide for fullness.

For a layered look, use an inside mount for your sheers, and an outside mount for your drapes. Drapes come in standard lengths of 63″, 84″, and 95″. 63″ drapes typically fall just below the bottom of the window frame. 84″ drapes typically fall just above or just at the floor. This type of drape is the most commonly used. 95″ drapes often fall on the floor so that the drapes “pool” for a luxurious look.

Now you know how to measure your windows for window treatments. Thank you, good-bye, and good luck!
