How to Install Bay Window Blinds

Updated February 21, 2017

The unique three-dimensional, three-section shape of the bay window changes the style and feel of a room, but they also require more careful consideration in the choice of window treatment. Blinds are an effective option, although installing them requires a little more measuring than regular set-ups. The secret to installing blinds properly is being aware of the extra angles involved, and using the correct hardware. The simplest method by far is to use separate blinds for each window.

Measure the width of each window and, with a pencil, mark the midpoints on each one. Remove a blind from the box and measure it to find its midpoint. Hold it up to the installation point so that the midpoints match, and be sure that there is enough room on either side so that the blinds won't intersect from window to window.

Mark and measure the exact locations on each window for the horizontal and vertical placement of each blind. Apply the carpenter's level to make sure that everything straight and aligned, and aligned across the entire bay window.

Check whether the brackets are alike or have right and left sides, and hold an appropriate bracket to the first location for the first blind. Nail the bracket to the window frame with the hammer. Attach its partner onto the other side of the frame. Repeat this for the next four brackets, always checking the level of each one and that the finished treatments won't interfere with each other.

Open the doors on the first pair of brackets and insert the ends of the blind into the brackets. Snap in the blind and close the doors securely. Do this for the other two windows.

Pull each blind's cord to open and close each one, and ensure that everything is working smoothly.


The bay window rod is steel, and has three adjustable sections, but it still requires that your window fit the same proportion possibilities as the rod. Curved tracks follow the angle of the window, but are hard to shape to the specific window, and require two people to install. The best fit will come from hanging the blinds inside the window casing.


Do not open the boxes with a razor blade or a knife to prevent cutting strings and blinds.
