How to Measure for Replacement Windows?

Every year, thousands of homeowners across the United States replace broken windows in their home. While replacing a broken window does take some time, it’s a simple process if one follows the right steps. The following guide provides simple tips and tricks on how to measure replacement windows before getting them installed.

When looking to measure replacement windows, it’s important to make sure that you measure from the right location. In the United States, most replacement windows come with a prebuilt frame. This frame contains the sliding mechanism in a wood or metal frame. This entire frame will fit inside the opening for a window.

When measuring, it’s important to check each corner of a window opening to make sure that the opening is square. In older homes, building materials like wood can often shift over time. This can cause a window opening to change shape. In some cases, the length on one side of a window opening will be slightly different than the length at the other side.

To make sure that there isn’t any sagging, it’s essential to measure the width of a window opening at the top, bottom and middle. The length of a window opening should be measured on the right, middle and left. If there is more than a one inch variation across the length or width of a window opening, it may not be possible to install a frame without some repair work.

When sizing a window frame, it’s critical to make sure that the frame is half an inch smaller than the length and the width of a window frame.

Depth should also be measured when installing a replacement window. It may be possible to adjust the depth of a window frame through the use of a miter saw; however, this isn’t possible on all windows.

When measuring the depth, it’s a good idea to use the old window’s depth as a guide. There are many decorative features on modern windows that can impact the installation of a window. Because of this, it may be a good idea to choose a window that has a shallow design; however, this will vary based on location.

Some windows require additional measurements for a proper installation. If the new window will be installed on an existing frame, it’s a good idea to measure the length, width and depth every five inches around the frame. Even small variations can impact a window installation.
