Easy Window Measuring Instructions

If you or someone you know can use a tape measurer and screw gun, you have all you need to measure and install like a pro by following these easy step by step instructions.


  1. We recommend measuring each window two (2) times for accuracy. Window measurements often vary by as little as 1/8″ which can affect proper fit and/or operation. Errors are only corrected by purchasing a new properly measured shade.
  2. Use a steel measuring tape and round down each measurement to the nearest 1/8″. Shades are made to the 1/8″ ONLY. Be sure to watch the video below and avoid measuring by bending the tape into corners!
  3. For large windows, we recommend using two or more shades on one headrail or tube. This reduces the load and may extend the life of the shades. You can measure to place the edges of abutted shades over architectural details such as mullions. Note fabrics may have a max width of 71″, 78″, 84″, 118″ etc.

Inside Mount (Recessed)

Measuring for Inside Mount diagram

Shade hangs inside the window frame (jambs). A minimum of 2 3/4″ recess is necessary for a flush mount with the front of window trim for HappyShades. Safeshades roller and other operating system minimums vary according to both width and length. For smaller recesses it is common to use an inside mount allowing a portion of the shade or its hardware to project beyond the window trim.

NOTE: Industry standard deductions are taken for all shades ordered as inside mount to insure proper operation. Light gaps will vary according to window construction. Light gaps for Safeshades rollers may vary from 5/8″ to 1+” according to the operating system. To minimize light leak for outside mount, we recommend a minimum of 2” is added to the window opening for all sides.

Outside Mount (Surface)

Measuring for Outside Mount diagram

Used when window depth is less than min requirements, for increased light control, or to hide imperfections. The shade is mounted to the wall or trim. For openings with trim or moulding it is often desirable to measure from outside edge to outside edge for width and from top edge to top of sill (assuming sill extends further than trim or molding) for length.

Doors: Outside Mount (Surface)

Measure a door for shades the Earthshade way

Hinged and/or French doors are measured for width (DIM A) from the edge of the glass to the edge of the hardware (escutcheon) and mounting the shade so that it is centered. This may balance shade and door operation with coverage (shade may need assistance getting around lever). We recommend adding 2″ to the top AND the bottom of the glass height to allow mounting hardware to clear internal door components (DIM E +4″). Standard Roman is generally the only system that will work with lever handles in the HappyShades line. Reverse Roll is not recommended for Safeshades on doors. It is generally preferred to specify operating cords on the hinge side to minimize obstruction of the door or shade operation.

  • Though we strive to control every detail regarding shade production, some patterns (including those that are GreenGuard or Oeko Tex certified) may not be suitable for our friends with chemical sensitivities. Please call for additional details.
  • Some patterns may require additional operating options based on ordered dimensions, conditions, and or customer interests. An Earthshade Representative will assist with recommendations.
  • Minor stretching and twisting is inherent to the materials and may require a varying amount of time to acclimate. Sun exposure may cause discoloration or fading.
