How to measure for installing two separate blinds in one window Menu

Two window blinds on the same headrail

If your window is too large to install only one blind or shade, you will need to install two separate blinds in the same window. These window coverings will require special measurements to make sure they will fit perfectly.

Note: These instructions do not apply to honeycomb blinds.

  1. Measure at the top, middle, and bottom of your window using our measuring instructions.
  2. To determine the size of your blinds, you must do a simple calculation. First, divide the total window width by two, then add ¼” to that number. This will be the size of each blind. Enter this number onto your order.

    For example, if your window is 80” wide, you would order two blinds that are 40 ¼” each.
    80”/2 = 40”
    40” + ¼” = 40 ¼”

  3. Choose inside mount when ordering.
  4. In the notes section, specify that you want both blinds on one common valance. You MUST click UPDATE in order to save your notes.
  5. To calculate the length of the valance, take the total width of your window and subtract 1/8”.

    If your window is 80” wide, your common valance would be 79 7/8”.
    80” – 1/8” = 79 7/8”

For inside mounted honeycomb shades 

  1. Measure at the top, middle, and bottom of your window using our measuring instructions.
     
  2. To determine the size of your blinds, divide the total window width by two. This will be the size of each blind.

    For example, if your window measures 80" wide, you would order two blinds that are 40” each.
    80" ÷ 2 = 40" .
