How to Measure for a Replacement Window

Be Precise

If your home’s windows are old and no longer providing the level of performance you want, it might be time for a window replacement project. Depending on the number of windows you need to replace, this project could turn into a significant investment in your home – though it’s one that could pay off in the form of improved energy efficiency and curb appeal. One way you can save time and expense is to do your own measurements for the window contractor you choose so they can simply order your new windows and provide installation.

Accuracy is Key

There are three steps involved in the gathering of proper measurements for your window installation project:

  1. Measure for width – Measure the horizontal distance across the window frame at the top, middle, and bottom. The smallest of the three measurements is your rough opening width. Be sure to measure from the surface of the jambs, not from the trim strips or parting beads.
  2. Measure for height – Measure the vertical distance across the frame on the left, middle, and right from the head jamb to the window sill. Once again, the smallest measurement is the one you should use for the window height.
  3. Measure for depth – There are many types of windows that may be too deep to fit in a typical opening, so this measurement is extremely important. Measure from the outside to the inside of the frame in several locations on the window, and once again use the smallest measurement as your final dimension.

Cold stays out in the winter. Cold stays in during the summer.

The best thing I love is the craftsmanship from NEWPRO. You'd never know we had the old door cut out because it was rotted from the New England weather.
