Roller shades offer an attractive and economical option for window shades. They can increase privacy, protect drapes and furniture from fading due to sunlight, and make a decorating statement. However, shades must be able to operate easily, so it is important to measure accurately and install them properly.
Before taking measurements, you must decide whether you want to mount your window shades inside the window casement or outside of it. An inside mount is normally used if drapes or curtains will be installed over the window shades, but it is not an absolute requirement. Outside mounts are typically used for window frames that are very shallow, such as three inches or smaller. If the windows are out of square, an exterior mount is sometimes used to hide the imperfections. Small windows can also be made to appear larger by mounting shades on the outside of the casement. In addition, an outside mount offers even more privacy and blocking of light and can be extended to cover the lower sill, if desired.
Always measure for window shades with a steel tape measure. Cloth tapes can stretch while you are taking the measurements, leading to inaccurate results. Older ones can be so stretched out of shape that readings can vary by as much as a quarter inch.
Never assume that windows on the same wall will measure identically. Always measure every window for which you are ordering shades. Widths should be checked at the middle, top, and bottom, while lengths should be checked in the center, left, and right. Take the smallest results and round to the nearest one-eighth inch. Round measurements for width down and measurements for height up. When you record the results, write them down as width followed by height.
Whether you buy shades custom made or off the shelf, you may note a difference between what you measured and the size of the window shades. Brackets, which take up space, are used to mount shades. The window shades must therefore be slightly less narrow than the window. This difference is usually between an eighth and a fourth of an inch although a half inch is sometimes required. There is also fabric allowed for a header that is wrapped around a roller. Standard allowance for the header is usually one foot.
If you are planning to mount shades outside the window frame, you need to make adjustments to the actual window measurements. Brackets are normally placed a minimum of 2 inches above the window casement and can be placed as many as 4 inches above it. This number must be included in your overall shade height. Width must also be adjusted for the amount of overlap you wish to have on the sides.
If there is trim around the casement, you may need to adjust measurements. Brackets need a flat and level surface for installation. Sometimes trim prevents this, so measurements must include an allowance to clear this trim. If not, they may not perform as you would like.
If the dealer from whom you are ordering your roller shades provides a set of instructions for taking measurements, follow their directions. There are a few manufacturers who use special brackets or different trim allowances, so it is best to use the method they provide for optimal fit. Improper measurements can cause unsightly gaps, so measure twice and order once.
