When you’re in the market for new or replacement windows, one of the most important things to consider is the size. While custom sizes are an option, many homeowners opt for standard sizes simply because they make the process easier, quicker, and more cost-effective. What are the common window sizes in modern homes?
Keep reading to learn more about standard windows of all types, from picture, to casement, to sliding, and more.
What Are Standard Windows?
The term “standard windows” refers to windows that have a set of dimensions that will fit in most modern homes. As we mentioned above, standard windows have several benefits: it is easier and more cost-effective to use a standard window than it is to design and manufacture a custom window with unusual dimensions. It’s typically also quicker to find a standard window in-stock.
When it comes to standard window sizes, they are generally indicated using four digits. A common double-hung window size, for example, is two feet wide by three feet tall and would be marked in one of two ways: “2030” or “2436.” (Some manufacturers refer to window size using feet plus inches, while others refer to window size using only inches.) When reading a window size, make sure to note which measuring system the manufacturer is using. Also, double-check whether the size refers to the rough opening or the exact framed opening for the window.
Common Window Sizes
What the common sizes are for a particular window will depend on the style of window. Common sizes for double-hung windows are different from sizes for casement windows, for example.

Getting the Right Windows
Measuring your windows is technically a simple process, requiring only a measuring tape, pen and paper, and possibly a ladder. However, for the average homeowner, it can get confusing and is easy to mess up. Mis-measure here, include the trim there, and all of a sudden, your window size is totally wrong!
This can be disastrous if you order—or worse, install—the wrong size. (Incorrectly sized windows that have been installed will be drafty, hard to open and close, or lopsided.) Plus, it can be very tedious to measure numerous windows in your home.
For that reason, we recommend asking a window company (like Jack’s Glass) to measure your windows and note your window sizes. With help from professionals, you can be sure that your windows are measured precisely and correctly. You’ll be guaranteed to end up with the correct size of windows—helping you avoid an expensive and time-consuming mistake.
