How to Measure

Please read carefully before ordering to ensure you get exactly what you need. Before taking any measurements, determine if the window treatment will be installed as an inside mount or an outside mount. Use a metal tape measure to measure accurately to the nearest 1/8-inch. Do not round down.

Inside mount treatments are installed inside the window casing. Inside mounts can also offer a clean, streamlined look. Outside mount window treatments are mounted outside the window casing. They are a popular choice when the blinds are going to be the only window covering. Extending them past the window provides maximum light control.
Determining whether you need an inside or an outside mount.
When you're measuring for inside mount blinds, accuracy is key. Fortunately, you can get measurements in three simple steps: Measure the inside of the window frame in three places for width: across the top, middle and bottom. This is because not all windows are built perfectly. Measure the narrowest width of the three measurements.Measure for height: at the left, middle and right side. Document the longest length of the three measurements. Measure the depth of the window so you know how deep the blinds can be. Please see photos for visual help.
Inside Mount
When you're measuring for outside mount blinds, allow for enough wall space to accommodate the mount. Here’s how to get accurate measurements: Measure the overall area to be covered. Measure both the width of the window and the height of the window. Consider adding an extra 3 inches to the width and height for optimum light control and privacy. Extending the blinds outside the window will also provide the space needed for the mounts and help the window appear larger than it actually is. Please see photos for visual help.
Outside Mount
Our factory will make your blind or shade to the exact measurements you provide. Be sure to allow extra space for the head rail and mounting brackets, which can be up to 2 1/2-inches tall. If you want increased light blockage and privacy, add a few extra inches outside of the window space. Make allowances for obstructions like doorknobs, deadbolts or moulding that might get in the way. If you have obstructions, spacer blocks or extension brackets are available to help your blind or shade extend far enough to avoid protrusions. Outside mounts require at least 2 inches of flat surface above the window or frame for mounting brackets. You may need projection brackets to clear the frame moulding.
