Measuring for Custom Roman Shades

Always use a metal measuring tape.  Record measurements to the nearest 1/8”.  Measure width first, then length.  If there are several windows in 1 room, start with the one on your left as you enter the room and work your ways clockwise.  Number each window.

Inside Mount Shade

Installing a Roman shade inside the window frame results in the cleanest look. If the window is framed in wood, the appearance is that of a picture frame around your shade. The treatment is out of the way, even when lowered. The disadvantage of an Inside Mount Shade is that you will lose part of your view and light even when the shade is fully raised. The blind will take up approximately 5-8” (depending on the length) at the top of the window when the blind is open.

    Follow these guidelines for accurate measuring:

    • Measure the inside width at the top and bottom.  Record the smallest number (to the nearest 1/8″).  We will deduct ¼” from the overall width.
    • Measure the inside height of the window at left and right sides.  This is the length.  Record the smallest number (to the nearest 1/8″).
    • Measure the depth of the inside of the window frame at the top of the window where the mounting board will go.   This measurement must be at least 1 ¼” for the mounting board to fit.

    Outside Mount Shade

    Installing a Roman shade outside the window trim allows you to raise the shade up to the top of the glass (assuming that you have adequate wall space between the top of the window and the ceiling) letting the maximum amount of light into the room. The sides of the shade usually extend to the outsides of the window trim, or if there is no trim, add at least 2″ to the window width. The length of the shade usually extends to the bottom of the window trim.

      Follow these guidelines for accurate measuring:

      • Width: measure and record the exact width of the area to be covered (to the nearest 1/8″).
      • Measure the height of the area to be covered allowing a minimum of 2” above the top of the window trim to allow for the headrail and installation brackets. Record this number (to the nearest 1/8″) as your length.
