How To Measure

Measuring For Blinds

Measure each window individually, as size variances are common.
Record width first, then height (also referred to as length) to the nearest 1⁄8″.
Measure width from left to right, height from top to bottom, using a steel tape measure. Do not use a cloth tape.

Select your window fashion type for measuring instructions:

Horizontal Blinds and Fabric Shades, including Innovative Shadings and Solar Shades
Inside mount:

Inside mount blinds and shades are installed inside the window casing. Minimum depth requirements vary by product and headrail type, or by tube size (for solar shades). Ask your designer or sales associate for details.
Measure the exact inside width of window casing from one inside edge to the other in three different places. Record the narrowest measurement.
Measure the exact height in three different places from top edge of opening to top of sill. Record the longest measurement.
Do not take any deductions for clearance. The factory will take necessary deductions for a perfect fit.
Measure the window diagonally in two places, as shown. If the two diagonal dimensions are not equal, we recommend an outside mount application for optimal shade function and aesthetics.
Note on Solar Shades: On Continuous Loop inside mounts, there is a 7⁄8″ light gap per side. On Cordless inside mounts, there is approximately 1 9⁄16″ total light gap (31⁄32″ on control end, 19⁄32″ on idle end). For optimal light and glare control, outside mount is recommended.

Outside Mount:

Outside mount blinds and shades are installed outside the window casing, covering an area larger than the window itself.
Measure the exact width to be covered. Be sure the measurement overlaps the window opening by at least 1 1⁄2″ on each side (3″ total overlap) to ensure light control and privacy.
Measure exact height to be covered, including desired overlap (typically from top edge of molding to bottom edge, or to top of sill if there is one).
The factory makes NO allowances on outside mount.

Vertical Blinds
Inside Mount:

Inside mount blinds are installed inside a window casing or door, or wall to wall in a room. The window casing must be at least 2 3⁄4″ deep for track flush mount or 3 3⁄4″ deep for louvers flush mount. Otherwise, an angle bracket may be necessary.
Measure the exact inside width of window casing from one inside edge to the other in three different places. Record the narrowest measurement.
Measure the exact height in three different places from top edge of opening to bottom, or top edge of sill if there is one. Record the shortest measurement.
Do not take any deductions for clearance. The factory will take necessary deductions for a perfect fit.

Outside Mount:

Outside mount blinds are installed outside the window casing, covering an area larger than the window itself.
Measure the exact width of window, including frame if there is one. Add 3″ for each side (6″ total overlap) to ensure light control and privacy.
Measure height of window from top edge of molding to bottom edge, or to top of sill if there is one. Add 3″ to allow for adequate mounting area above the window.
If blind extends to floor (i.e., to cover patio door), measure height in three places, take the smallest measurement and deduct at least 1⁄2″ for clearance so the louvers don’t touch the floor.
The factory makes NO allowances on outside mount.
NOTE: If you want the entire window uncovered when the blind is fully open, you may need to add more than 6″ to the width. Ask your retail sales associate for the correct amount of overlap.
