The Standard Window Sizes for Homes

If you’re in the market for new windows, you’ll want to educate yourself on your options before making any decisions. This includes understanding standard window sizes and custom-sized windows.

While custom sizes are available, choosing standard-size windows means faster installations, reduced costs, and a wider variety of styles and brands to choose from. Let the pros at Quality Window & Door walk you through standard window sizes for homes.

What Are Standard-Sized Windows?

Standard-sized windows are designed for the average home and are pre-made to fit. You’ll want to familiarize yourself with the types of standard windows, such as double-hung, casement, picture, sliding, and hopper windows.

Choosing standard-sized windows has many benefits. They’re readily available from many manufacturers, so you can get your desired style. They’re ready to go right out of the box, which means a faster installation and less hassle. They’re also more affordable since they don’t need to be custom-made.

At Quality Window & Door, we work with the best window brands in the business:

How To Tell What Window Size You Need

To understand what window sizes you need, you’ll need to start by properly measuring. Here’s how:

Width: Measure between the inside jambs at the top, middle, and bottom.
Height: Measure from the sill to the top jamb in three places, and use the smallest number.
Depth: Measure the thickness of your window frame to get the depth measurement.

It’s important to note that window contractors use a notation marker to order windows. The notation indicates a window’s combined width and height. The first two digits in the notation are the window’s width, while the second digits are the window’s height. For example, the notation number of a 2′ 8″ wide and 4′ tall window would be 2840.
