1. Use a steel measuring tape & Measure to the nearest eighth of an inch - don't round your measurements.
2. Reversing width and height when measuring. Width is the side-to-side measurement. Height is the top-to-bottom measurement. The width is always given before the height of the Door or window. For example, an order 48 x 72 would be manufactured 48 inches wide by 72 inches high. To avoid confusion, as you measure put a W next to width measurement and an H by the height measurement.
3. Not checking the measurements in three places on both the width and height of the door or window will cause in the wrong size. Use a ladder or stool to reach the top of high windows. Many windows are not square, so the width should be measured at the top, in the middle and at the bottom. Also check the height of the window in the middle and at both sides. When placing your order use the smallest size of the three measurements.
4. Not allowing for obstructions that will hamper the operation of the blind. The most common obstructions are inside the window frame are window cranks and handles. We can provide fold down window cranks for most windows.
