How to Measure Windows

Measuring for new windows or replacement windows is easier than you think. And to make it even easier, we share some industry trade secrets in the video below.


Windows in Brick or Rock

1. From the outside of the home measure the width of the opening at top, middle, and bottom.
2. Take the narrowest measurement and subtract ¼ inch. This will be the width of the window you order.
3. Measure the height of the opening at left side, middle, right side.
4. Take the shortest measurement and subtract ¼ inch. This will be the height of the window you order.
5. Repeat for each opening.

"My partner and I always thought we could install our own windows but we were worried about ordering the wrong sizes. Window E-store made it so easy with their "How to measure" video and instructions. We followed the easy directions and our windows came out perfectly!

"We live in a small community. The only option we had for new windows was the local lumber yard. We weren't too thrilled with the quality of window they offered. We checked out the quality of Window E-store windows and found out they are made by the top high performance window manufacturer in America. They even gave us a list of AAMA certified installers in our area! Super happy with our new windows." - Richard R.
