As usual, if you’re unsure or feel uneasy, stop by your local companies for replacement windows in Laguna Niguel, CA. When measuring for a replacement window, you are attempting to establish the size of the pocket into which the new window will be installed. The region within the jambs where the new window will be put is referred to as the window pocket.

However, replacing windows requires more than a trip to the local window shop or large box contractor store; you must know how to measure windows! In this post, we will go over how to measure replacement windows in detail, as well as the exact processes for measuring vinyl replacement windows.

If you’re still hesitant, it might be time to consult with an expert that specializes in measuring and installing replacement windows.

Furthermore, professional window installers may be aware of a few things that do-it-yourselfers overlook while measuring vinyl windows. This includes things like if the frame is in good shape. Frames, like vinyl windows, frequently require replacement due to age or damage. Water-damaged or mold-infested frames must be changed as soon as possible, and window installation pros will be able to rapidly inspect your frame and present you with solutions moving forward.


Step One – Gather your resources and conduct your study.

When it comes to measuring replacement window size, you’ll need the right tools.

  • Measuring Tape
  • Level
  • Pencil
  • Notepad


When deciding how to measure full-frame replacement windows, you must first determine what you want. To ensure that you are prepared and know what to do, you will need to gather the tools and years of knowledge through a combination of YouTube, how-to guides, and a trip to the local hardware shop. It is generally recommended that unless you have prior experience measuring for a new or replacement window, you leave it to the specialists. This sentiment stems from the fact that windows are difficult to measure, and while mistakes may be corrected, they quickly pile up in terms of money and effort spent attempting to solve an issue that an expert could handle in minutes.


Step 2: Determine the height of your window.

Repeat the previous step, but this time measure the height of your window in three places: far left, center, and far right.

The measurement should be taken from the head jamb to the windowsill. When measuring, once again move the sash out of the way.

As you proceed, take notes on your measurements. Your window’s height is the smallest.

It’s important to remember that if your window isn’t rectangular or has an arch on the top, measuring the height will be a little different. Begin by locating the window’s center. Then, add 12 inches to the height of the window measured from the top center to the front of the frame.


Step 3: Determine the Jamb Depth

Locate the deepest portion of your window and measure it. Take this measurement in many places; the smallest number is the depth of your window.

(While a window depth measurement is not required to order replacement windows, be sure your window depth is at least 3 14 inches. Otherwise, it’s too thin to fit most windows.)


How Do You Determine Whether Your Window Frame Is Square?

A replacement window must be square to fit securely in your current window frame. If not, you must fix the frame.

Here’s how to do it:

Measure your window frame diagonally from the top right corner to the bottom left corner from the inside of your home – note down the measurement.replacement window in Laguna Niguel CA
