When it comes to dressing a window, shades are probably the most versatile covering in terms of being functional as well as decorative. There’s a dizzying array of options for all types of window shades, from colorful roller shades to Roman shades made of designer fabrics. You can elevate a room’s style and decide how much light or privacy a room needs with a variety of sheer, light-filtering and room-darkening patterns and materials.

You should keep in mind that with multiple windows to cover, costs can add up for materials and installation. Make sure you consider how a particular style fits your window, advises Sheri Stouffer, owner of Finishing Touches design studio in Castle Pines, Colorado. “Put a budget together in your brain. You might want to spend more money where people gather, for example,” she says. “Think about your windows — what they look like and the story behind the window. How the window opens can be a factor. So now you can narrow down options on what would work best for your scenario.”

Here’s a guide to five popular shade options and what design professionals have to say about them.
