Horizontal Shade - Measuring

Homes all across the country use horizontal shades. Because of their versatility, you can use shades literally in any room of the home. In addition to changing the appearance of a room, horizontal shades are a great way to block out sun and provide privacy. However, to ensure you get the most out of your shades, you need to take accurate measurements, using a steel measuring tape instead of cloth.

Hanging with an Inside Mount

If you plan to hang the shades with an inside mount, meaning inside the window frame, which is the most popular option, you would need to measure differently from that of an outside mount. Although an outside mount is another good option, an inside mount looks a little more organized and neat. Keep mind that the minimum depth requirement for an inside mount versus a flush mount would vary depending on the type of horizontal shades you choose.

Mounted Legnth

For instance, if you were to go with a pleated shade, which creates a look of elegance, an inside mount would need a minimum of 1-inch, whereas a flush inside mount would need 1 1/2 inches. Cellular shades are also a popular choice in that they are great for blocking out hot UV rays. In this case, an inside mount would require at least 3/4-inch while the flush inside mount, 1 7/8 inches. You could also purchase natural wood shades, which are simply beautiful. For this, you need 1-inch for the inside mount and 2 inches for the flush inside mount.

Horizontal Shade Width

For the width of horizontal shades, you want to measure in three different places, which will give you a more accurate reading. Once you have all three numbers, use the lowest, rounding to the nearest 1/8-inch. Then for the height, you want to do the same, measuring on the left, in the center, and on the right. Again, take that number, rounding it to the nearest 1/8-inch. In both cases, you do not want to do any other modifications since the manufacturer will do this for you if necessary.


To give you an idea of adjustments the manufacturer would make, cellular shades would have a 1/2-inch adjustment for fabric and 1/4-inch for the head rail. Now, if you decided to choose the pleated shades, then fabric would be adjusted by 3/8-inch with the head rail at 1/4-inch. Of course, another great choice is Roman shades, a beautiful choice. The adjustment in this case would be a 3/8-inch or woven wood shades, a 1/2-inch change. Remember, as long as you measuring as directed and stick with the 1/8-inch rounding, the reset will be handled when you order the shades.
