How to Choose the Right Curtain Lengths

The right curtains can make a room feel finished, more stylish. Choose the wrong curtain length, however, and you may end up with an ill-fitting curtain that throws off a room’s appearance in a way that nags at you. The wrong length can compromise functionality as well. A curtain that’s too short won’t cover the entire window and a curtain that’s too long may drag on the floor and be harder to open and close. Figuring out the correct curtain lengths can help you avoid any of these irritations, to say nothing of dissatisfaction with your purchase.

Industry Standards

You can find curtains online or at your local provider in these standard lengths:

  • 63 inches
  • 84 inches
  • 94 inches
  • 108 inches
  • 120 inches

If you prefer custom-length curtains, keep this in mind: Curtain width is also important. For a balanced look, the longer a curtain, the wider it should be.

How to Measure for the Right Curtain Length

A good rule of thumb is to take the width of your window and double it. To make your windows appear wider and higher, add a few inches to your measurements. As a general rule, add 4 inches from the top of the window. For reference and design ideas, here are three popular curtain lengths:


Windowsill curtains end about a half inch above or right at the window sill. Casual and charming, they look great in kitchens, or spaces with elevated windows.


Apron curtains hang about 4 inches below the window sill. They’re suitable for casual areas, like a breakfast nook or any space where radiators or furniture would block full-length curtains.

Floor-Length Curtains

These curtains end at the floor or a half inch above it. Polished and stylish, they’re one of the most common choices for living rooms and can make a window, and thus a room, look taller.
