How to Measure Replacement Windows?

If you’re looking for a home improvement project, replacing your windows is one of the most cost-effective options. But in order to have a successful window replacement, you must accurately measure your current windows. Let’s go over the steps of measuring your windows correctly so that your new replacements fit perfectly. Learn How to Measure Replacement Windows?

How to Measure Replacement Windows?

  1. Measuring Width and Height – The first step to measuring windows is to record the width and height of each window frame opening. You should use a steel tape measure or a laser measure and write down the exact measurements in millimeters or inches. Measure both the width and height at least three times to make sure you are getting an accurate reading. Also, make sure not to include any trim when taking these measurements; they should only include the actual frame opening.
  2. Measuring Depth – Once you have taken measurements for width and height, it’s time to measure depth. This is also known as “rough opening” because this will be the size of the rough opening once the new window is installed in place of the old one. To get an accurate measurement of depth, measure from inside wall to inside wall on either side. Again, use either a steel tape measure or laser measure and write down exact measurements in millimeters or inches. Also make sure not to include any trim when taking these measurements; they should only include the actual frame opening.
  3. Measuring Sill Angle – In addition to width, height, and depth, you will also need to take measurements for sill angle if you plan on replacing sliding windows with double hung windows (or vice versa). To do this, use a level tool to determine that angle of inclination between two surfaces (e.g., window sill versus outside wall). Use a protractor if needed in order to get an accurate measurement; mark down results either in degrees or radians depending on which type of angle measurement tool you are using.

Conclusion

Accurately measuring your existing windows before purchasing replacement ones ensures that your new replacements will fit perfectly when installed in place of old ones—saving time and money! When measuring, record all dimensions (widths, heights, depths) plus any angles (for sliders versus double hungs) using either steel tape measures or laser measures. Also make sure not to include any trim when taking these measurements; they should only include the actual frame openings so that your new replacements fit perfectly without having gaps around them once they are put into place! With these tips in mind, you can now start measuring replacement windows with confidence!
