Measuring for Replacement Windows

When you’re buying window replacement in Campbell, CA you need to make sure you have accurate measurements for each window you plan to have replaced. Not only does this ensure that you are communicating correct information to the replacement windows company, but it also ensures that you get a more accurate price quote for the replacement windows.  

Before you take measurements you need to know the parts of the window, because the terminology is critical to making sure you’re measuring in the right places. The window jamb encases the window. The window sashes are the middle parts of the window that meet – and can be locked – when the window is closed. The window sill is the bottom ledge of the window. All height and width measurements for window replacement will be within the area of the window jamb itself.  

You’ll need to take measurements to size your window. A key basic of the windows to remember is that when you are measuring windows, everything is done in threes. You’ll measure window height, width, and depth three times in three different places on the window to get an accurate measurement.  

For the window height, you’ll need to measure from the window sill to the bottom of the head jamb (the top horizontal part of the window frame). Open or close the window sash as needed to get it out of the way so you get accurate measurements. Take measurements from the farthest left, the center, and the farthest right. From these three measurements, choose the smallest to get the window’s “rough opening height.”   

For the window width, you’ll need to measure at the widest point inside the window frame. Open or close the window sash as needed to get it out of the way so your measurements are accurate. Take measurements at the bottom, in the center where the sashes meet, and at the top. The smallest of the three measurements is the window’s “rough opening width.”  

For the window depth, you’ll need to measure from the outside of the vertical jamb to the innermost part of the vertical jamb. Take measurements at the top, in the center, and at the bottom above the window sill. The smallest measurement is the window’s depth.  

You should repeat this entire process at least two times to ensure that the window measurements are accurate because these will be the measurements the replacement windows company will use for your replacement windows. If any of these measurements is off by the slightest amount, your replacement windows will not fit properly.  

Windows replacement is a big investment so getting it right the first time is a critical step in making sure that your replacement windows fit snuggly and tightly. Most likely, your replacement windows are to eliminate gaps, cold air coming in during the winter and hot air coming in during the summer, condensation, and higher energy bills. If your replacement windows don’t fit properly, then you’ll still experience the same kinds of problems.
