What size window do you need? Rough opening vs. actual size

Here’s the deal: when it comes to measuring windows, what size window do you need? Rough opening vs. actual size are the two terms you’ll need to know. It’s essential to consider both measurements when selecting a window to ensure it fits properly on your wall and looks good in your space.

The rough opening refers to the size of the hole in your wall where the window will be installed. It’s typically larger than the actual size of the window to allow for proper installation and insulation. The actual size of the window, on the other hand, refers to the physical size of the window itself. 

 

How do you take these measurements?

So, what size window do you need? Rough opening vs. actual size are the two key figures in helping you determine this. Finding these numbers is a simple process that can be done with a tape measure. To get started, measure the height of the opening from the top of the bottom sill to the bottom of the top header. Next, measure the width of the opening from side to side. Measuring the opening at different points is essential to ensure it is level and square. 

Once you have these measurements, add an extra inch to the height and width to allow for proper installation and insulation. This will give you a rough opening measurement. You’ll need this to choose the right window for your space. 

Taking the actual measurement for a window is just as easy. To start, measure the height of the window from the top of the frame to the bottom. Then, measure the width of the window from side to side. Again, be sure to measure at different points to ensure accuracy since the frame may not be perfectly square. 

When you have these measurements, you have the actual size of the window. It’s important to take into account the frame as well, as it will add to the overall window size. By measuring carefully and factoring in the frame, you can be confident that you’ll select a window that fits perfectly in your space and looks great, too!
