How to Cover Arches and Other Specialty Shape Windows

Do you have an odd shaped window? Does one or more of your windows just not fit in? Most homes have at least one. Specialty shaped windows, windows that are not the traditional square and rectangle shape, are beautiful to look at but when it comes to covering them, many people don’t know which route to take. Here, I will show you some options so that you can best decide which route it right for you.



Cellular shades, or honeycomb shades are an excellent option for specialty shaped windows. If your windows are arched at the top you have two choices.

The first option would be to have a fan, or sunburst such as the windows above. This option can be either fixed, or movable much like a fan.


HD Duettes Arched

The second option would be a moveable arch shade system such as the one above. With this choice, all of the pleats can be aligned, both the arch and the shades below. This creates a consistent, unified look.

Cellular shades are also great for sunrooms with skylights. Notice how these Hunter Douglas Duette Window Shadings work with triangular, or rake windows, as well. With this application, the rake windows would be fixed, or inoperable.


With the use of a palladian shelf, many manufacturers offer fixed shade options that are inoperable, however, can create a consistent look with coordinating shades in the room. Below are examples of fixed shades.

Another great option for covering specialty shaped windows is the shutter. Also known as plantation shutters, these custom window coverings are like furniture for your windows. For an arched window, you have the same options as a cellular. You can choose the sunburst looked or have a continuous arch. You can also use shutters for others shapes such as ovals, hexagons, half-circles, rake windows and so on. Because of their versatility, shutters are our favorite option for funky shaped windows!

Most people prefer to mount their window coverings inside of their window frame, creating a truly custom look. However, if you want to be able to cover an arched window completely you can always mount your window treatment outside of the window frame. In the example below, our client desired a roller shade and chose to do just that. These motorized roller shades can be raised completely and hidden in the cassette valance above the windows. In this way, our client was able to cover the windows without being forced to have an obstruction such as a palladian shelf.

Many of our clients with arched windows opt to leave the arch top open. This is a great option for clients seeking a budget friendly solution. I would not recommend this for bedrooms where most people prefer room darkening options to optimize sleep. However, if privacy and glare is not an issue, you can always just leave your specialty shapes bare!
