You’ve made the decision to replace your home’s windows and doors, and now you’re asking yourself how do I measure them for replacement? Proper measurement of windows is essential in successfully installing new or replacement windows in a home. Because of the importance of having your windows built to the exact size necessary to ensure optimal performance, we always recommend you hire a professional to tackle the job because more goes into the project than many people realize. And, if the custom-built replacement window does not fit perfectly, you will be responsible for this, and may then need a new one built or the existing opening modified to make it fit (which defeats the purpose of having a custom window made in the first place).

 

Even if you’re planning to hire a contractor to do the job, you may want to know how to measure for replacement windows to ensure you get the right size. Following these Ranebrook Windows guidelines will help to ensure precision and therefore, the best performance of your new windows. These recommendations are based on the installation of a typical replacement wood double-hung window into an existing wood double-hung window frame.

WHAT NEEDS TO BE MEASURED FOR A REPLACEMENT WINDOW

 

To get the best result, take measurements from the outside opening (brickwork opening) of both the width and the height.

Note: Never measure the old frame or door, only measure the brickwork opening!

WIDTH
HEIGHT
  1. Measure the width of the window or door opening at the top, middle, and bottom.
  2. Take the narrowest measurement and deduct 10mm. This will be the width of the window you order.
  3. Measure the height of the opening at the left side, middle, and right side.
  4. Take the shortest measurement and deduct 10mm. This will be the height of the window you order.
  5. Repeat for each opening.
