How Wide Should Your Window Treatments Be?

Getting the width right makes the difference between window treatments that look professionally installed and ones that obviously aren't quite right. Too narrow and you'll have light gaps; too wide and they won't fit properly or operate smoothly. If you've ever wondered how wide should window treatments be, the answer depends on what you're installing and where you're mounting them.

At The Shade Shop Inc., we measure and install window treatments throughout the Grand Rapids area on a daily basis. Here's what you need to know about getting the width right for different types of window coverings.

Inside Mount vs. Outside Mount: The Foundation

Before we discuss specific measurements, it's essential to understand the available mounting options. Inside mount means your window treatment fits within the window frame itself. Outside mount means it attaches to the wall or molding above and around your window opening.

An inside mount creates a clean, streamlined look and works great when you have deep enough window frames. An outside mount provides more flexibility in terms of size and can make windows appear larger than they actually are.

How Wide Should Curtains Be?

Curtains almost always mount outside the window frame on a rod or track. For a complete, luxurious look, your curtain panels should measure 1.5 to 2.5 times the width of your window.

The rod itself should extend 4 to 8 inches beyond each side of the window frame. This allows you to pull the curtains completely to the side when you want maximum light and provides better coverage when they're closed.

How Wide Should Blinds Be?

Blinds work with both mounting styles, which affects their width. For inside mount blinds, measure the exact width of your window frame at the bottom, middle, and top, and use the narrowest measurement. The blind manufacturer will make slight deductions to ensure proper fit and operation.

For outside mount blinds, add 3 to 4 inches to each side of your window frame. This minimizes light gaps and gives you better coverage.

How Wide Should Shades Be?

Shades follow similar rules to blinds, as they're often mounted in the same way. Inside mount shades need precise measurements of your window frame's interior width; even being off by 1/4 inch can cause operational problems or unwanted light gaps.

Outside mount shades should overlap your window frame by a minimum of 3 inches on each side. This extra coverage improves light control and energy efficiency.

How Wide Should Shutters Be?

Shutters typically mount inside your window frame; however, outside mount is also possible. Inside-mount shutters require highly accurate measurements—we're talking precise to 1/8 inch. The panels need to fit snugly in the frame while still allowing enough clearance for smooth opening and closing.

For outside mount shutters, you'll want to extend at least 2 to 3 inches past the window frame on all sides. This creates a better light seal and gives the shutters more visual presence.

Why Professional Measuring Matters

When it comes down to it, measuring for window treatments is trickier than it looks. Windows aren't always square, frames aren't always level, and small measurement errors create big installation problems.

We measure precisely, account for any irregularities in your windows, and install everything so it operates exactly as it should.
