You’ve looked at countless window treatments, debated wood vs. faux blinds, and finally made your selection. Only one step remains: You need to measure for your wood blinds. In this guide, we walk you through how to measure for wood blinds, both inside mount and outside mount. Here’s what you need to know:

Before You Begin




  • Take all measurements to the nearest ⅛ inch.
  • Always keep track of which dimension you’re measuring for and ⦁ list the width before the height (W x H) to avoid confusion.
  • Measure each window individually, even if they appear to be exactly the same size to the naked eye. This will ensure that your blinds offer the best fit possible.
  • Use a steel tape measure for the most accurate results.

How to Measure for Inside Mount Wood Blinds

    Inside mount blinds are installed inside the window frame or casing for a sleek look that doesn’t stick out from the window. Inside mount blinds are an especially good choice if you want to hang an additional window treatment, such as a curtain, over the window or if you plan to put furniture  relatively close to the window.

    • To confirm that you can inside mount your faux wood blinds, measure the depth of the casing or window frame. Consult the specifications for your desired window treatment to double check that the window is deep enough to support an inside mount. If the depth of your window isn’t large enough, you will have to outside mount the blinds.
    • Measure the width of your window at three locations: the top, middle, and bottom of the frame. Select the narrowest of the three measurements and use that as your overall width measurement for the blinds.
    • Measure the height of your window at three locations: the left, center, and right of the frame. Select the shortest of the three measurements and use that as your overall height measurement for the blinds.
    • When ordering the blinds, use the exact measurements you took and do not take any deductions. The manufacturer will take care of any necessary deductions for you, so, if you preemptively take them, you’ll run the risk of your blinds being too narrow or too short.

    How to Measure for Outside Mount Wood Blinds

    If your window frame isn’t deep enough to support the blinds on an inside mount, then you will have to outside mount them by installing them directly on the window trim. Outside mounting your wood blinds also provides more coverage and lets in less light since the blinds overlap the edges of the window, which may be a consideration as well.

    • To confirm that you can outside mount your custom wood blinds, measure how much area you have for a flat mount above the window. Consult the specifications for your desired window treatment to double check that the area is large enough to support an outside mount. If your trim isn’t wide enough, you may have to outside mount the window on the wall above the trim.
    • If your window has trim, measure the width of your window at three locations: the top, middle, and bottom of the frame. If your window doesn’t have trim, measure the width of the window itself in three places and add two inches to each side for enough coverage, for a total of four additional inches. Select the narrowest of the three measurements and use that as your overall width measurement for the blinds.
    • To determine the height of your blinds, see if you have a protruding window sill or not. If you do have a protruding window sill at the bottom, measure from the sill to three inches past the top of the window opening to accommodate for mounting hardware. If the window sill doesn’t protrude, start measuring two inches below the sill, and then go three inches beyond the top of the window opening so you’ll have enough room for the mounting hardware.
    • Once you’ve determined your starting place, measure the height of your window at three locations: the left, center, and right of the frame. Select the shortest of the three measurements and use that as your overall height measurement for the blinds.
    • Unlike inside mount blinds, outside mount blinds are not manufactured with any deductions taken from the measurements you submit. You will get the exact size that you ordered, so make sure that you have measured everything correctly and submitted the dimensions that you wanted.
