How Do I Measure My Window for Replacement?
Window installers usually handle measurements to provide replacement window glass and framing that fit the aperture. Incorrect measurements cause installation issues, such as last-minute modifications, delays, or added charges for order replacement. Letting the installer measure the window frees you from such liabilities but you can take rough measurements for quote estimates. Here’s how to measure your window for replacement:
Measure From Outside
Window measurements are usually taken on the outside of your house. Measure the aperture opening where your window fits. Don’t measure the frame unless you intend to retain it for your new replacement window glass. Check the installation to avoid measuring badly fitting frames. The measurement should be from brick to brick in the opening left when your old window is removed from the wall.
Scrape away any insulation and rendering to expose the edge of the bricks before measuring. Keep the measuring tape straight and taught to get accurate readings of the width, height, and diagonal dimensions. Measure everything twice and compare the readings for accuracy. Get a third reading if you notice a big difference.
Measure Width and Height
Take three measurements for the width: top, middle, and bottom; and three for the height: left, center, and right of the window opening. Measure the width from jamb to jamb instead of the trim height from the sill to the top jamb. Record the smallest measurements for width and height to ensure the new window fits. Measure the depth from the inside trim to the exterior stop and include the trim and frame when planning for full-frame replacement. Take diagonal measurements from top-right to bottom left corner and top-left to bottom-right corner. If the two readings are the same, your window opening is square. Old windows may become racked, where the frames and openings drop and become misaligned as the building shifts. Racking can cause fitting problems and require experienced installers.
Deduct As Recommended
Window manufacturers usually ask installers to deduct a few millimeters from brick-to-brick measurements to allow some tolerance during installation. Tolerance allows the window to fit properly and accommodate natural shifting with minimal issues. If the tolerance is too small, the window may not fit after applying the sealant, and forcing it could compromise structural integrity. Too much tolerance leads to micro gaps between the wall and frame, allowing heat exchange, dust, and draft.
Windows have unique requirements for tolerance. The deductions used for your old window may not work even with a similar design. Consult the manufacturer to determine how much they recommend you deduct from the measurements. You can let the installer handle such consultations, measurements, and deductions.
Hire a Window Installer
Reputable window installers handle everything from initial measurement to fabrication and installation. Hiring an installer frees you from the responsibility of measuring your window opening. The installer can help you measure all sections required to customize your frame and replacement glass. They have the training and equipment needed to measure hard-to-reach windows. Commercial buildings, apartment complexes, and multistory homes feature high windows that may not be accessible from outside. Professional installers have ladders and other equipment they use to take measurements safely. They have safety protocols to minimize the risk of fall accidents when measuring high windows. Window installers cover any property damage or issues during measurement and installation.

Measuring windows for replacement involves determining the correct dimensions for the framing and glass. Window designs are unique and may feature one or more glass panels separated by framing. Such designs require more complex measurements to achieve precise fabrication. Consult a reputable replacement window glass company today to find out more about their services and options.
