How To Measure Windows For Shades

How To Measure For Inside Mount Roller Shades

Inside mount roller shades or blinds are installed inside the window frame or casing. For inside mounting, follow these steps:

Measure the width of each window. Measure your width only at the top of the window for roller shades.
Measure the height of your window opening in three places: left, center, and right. Circle the tallest measurement - this is the number you submit for your window’s height.
Measure the depth of your window frame, from the front of the opening to the glass. You’ll need this measurement to ensure your window recess meets the minimum depth requirement for an inside mount.
Order at the exact opening size with no deductions. During production, the factory will apply a small deduction of approximately 1/8"(0.3cm) to ensure a safe and proper installation.
Double check that your measurements follow the width by height format (W x H).

How To Measure For Outside Mount Roller Shades

Outside mount roller shades or blinds are mounted on the window molding or wall above your window. Outside mount shades are a good choice if an inside mount is not possible due to window depth. For outside mount roller shades, follow these steps：

Check the mounting requirements on your roller shades to ensure you have enough flat surface for the mounting hardware.
Measure the exact width (left to right) of the window frame or how wide you would like the blind to be. Be sure to measure wide enough to cover the entire window and provide maximum light coverage.If your window has no trim, we recommend adding two to three inches on each side of your window to provide light gap coverage and privacy. Mark these additions on each side and measure the width between them in a straight line. Example: If the window opening is 38” wide, it might be helpful to order 42” if the space allows. This will provide 2” coverage on each side of the window.
Measure the height you would like the blind to be by measuring top to bottom. Be sure to measure high enough to cover the entire window and provide maximum light coverage. Example: If the window opening is 64” high, it might be helpful to order 68” if the space allows. This will provide 2” coverage on top and bottom of the window.
Double check that your measurements follow the width by height format (W x H). Remember, with outside mount roller shades, your product will be made to the exact specified size.

Taking Standard Bracket As Example

If the top frame of your window is uneven or the corners are curved, which prevents interior or ceiling installation, side installation is the best solution.
