Trapezoid Window Blinds & Shades

Natural Shades in Standard Roman Style with Motorized Lift.

What is a trapezoid window?

For the purposes of discussing window treatments, a trapezoid window is one where the top side of the window is at an angle.

These windows are most often seen in living rooms and other rooms with cathedral ceilings. The trapezoid shape reflects the soaring angles of the ceiling. It can be a stunning look.

But those windows, left uncovered, provide no privacy or light control. However, many homeowners leave these windows bare because they don’t know how to cover them or find it too much of a challenge. That’s too bad, because DIYers meet this challenge every day.


Let’s look at the options for covering trapezoid windows.


Cellular Shades

Cellular shades come in a variety of colors. Their even pleats look great on nearly any window. They also provide excellent insulation against heat and cold.

Pleated Shades

Available in a huge array of colors and patterns, pleated shades can add a strong decorative element to your trapezoid-shaped windows.

Aluminum Blinds

Nothing beats aluminum blinds for versatility and durability. They are available in a range of colors, making it easy to find blinds that match your décor. They resist dust and are highly durable.


Getting It Right

In challenging situations where the window shape is imperfect—that is, not even or straight—a template is needed. This can give Bali a precise picture of what you need. The process involves you creating a shape that Bali can use to craft your blinds or shades. The process is simple and the result is a window treatment that fits your unique trapezoid window.
