These basic tips will get you perfect measurements for window treatments
How to Measure Inside Mount Blinds
Inside mount window treatments are installed inside the window frame or casing – they provide a sleek, clean look which can showcase your window size and moldings. If you’re interested in measuring for inside mount blinds, follow these steps:
- Measure the exact inside width of window frame from one inside edge to the other. Take three measurements, one near the top, one in the center and one near the bottom. Record the narrowest measurement.
- Measure the exact height in three places, left, center and right from top edge of opening to top of sill. Record the longest measurement for horizontal blinds.
- Do not take deductions on inside mount measurements. The factory will take an 1/2“ allowances for operating clearance.
- Measure the window diagonally in two places as shown. If the two diagonal measurements are not the same, we suggest an outside mount application for the best shade performance and appearance.
How to Measure Outside Mount Blinds
Outside mount window treatments are mounted on the window molding, wall, or ceiling above your window. Outside mount blinds or shades can make your windows appear wider and longer while also providing better light control and privacy options. You may be required to install an outside mount if your windows do not have sufficient mounting depth.
Follow these simple steps to measure your windows for an outside mount window treatment:
- Measure the exact width of area to be covered. Be certain the measurement overlaps the window opening by at least 1 1/2” on each side to ensure privacy and light control.
- Measure exact height to be covered, including desired overlap (usually from top edge of molding to bottom edge, or to top of sill). If there is no sill, measure to where the blind is to reach.
- The factory does not make deductions for an outside mount.

Record opening dimensions, depth and clearance, exposure, glass and trim conditions, view and privacy goals, operating reach, daily traffic, power and control needs, product identification, photographs, and any building or community requirements before relying on a recommendation.
When to compare another option: General guidance cannot replace field measurement, current manufacturer documentation, a site-specific installation plan, or written warranty terms for the selected product.
Ed’s Recommendation
“I often recommend more than one treatment in the same property because the glass and daily needs change from room to room. The goal is a coordinated plan, not a forced one-product package.” — Ed Torres
