How to measure a window for replacement 

As with any project, the first thing you need to do is gather all the necessary tools. In this regard, you will need a ladder, measuring tape, paper, and a pencil. In addition, we would recommend purchasing a slide rule which is the most accurate in the industry.

Measuring width

If you Google how to measure a window for replacement, we are sure that all articles will tell you that the first step is determining the window’s width. Then you are going to measure horizontally at the top, the middle, and the bottom. You need to record all these measurements and make sure they are accurate. Otherwise, the windows won’t fit, and you’ll have to order them again, which will cost you more money. Remember to clarify how you are getting the width. For instance, from frame to frame.

Lining around the window

When most people ask how to measure a replacement window, they expect to find instructions to determine the width and height. However, if you have lining around the window, it is crucial to get those numbers as well. First, make sure that your windows have a plastic or aluminum liner. If that is the case then, those measurements are necessary to get the right windows. In some instances, it won’t be possible to access the liner. Then, you’ll only need to add half an inch to the numbers you already have.

Measuring Height

Whether you want to know how to measure a bay window for replacement or a regular one, a mandatory step is getting the height. This process is similar to the one in step one. You are going to take the ladder and measuring tape. Then, instead of doing it horizontally, you are going to take the measures vertically. You will have to do this three times on the left, the right, and in the middle. Remember to record the measurements accurately, or you could end up with windows that won’t fit your frames. A final reminder, check you are placing the tape or slide rule at the highest point.

Measuring the depth

Whenever you are planning to replace your windows, it is crucial to measure the depth. Sometimes, this element can change the available models and characteristics. That’s why we will advise you to measure this twice. The depth of your window will be what extends in front of the frame. 

You might be wondering, what happens if I can’t open the window? There is no need to panic because there are a couple of ways to help you figure it out. First, you can measure the depth on each side of the window and add it. In case you are not able to discover the thickness, just write down the standard, which is 3 mm. Even though this is just an estimate, it will be useful when you order the new windows.

Round the numbers

Now that you’ve got all the necessary measurements, it is time to round down the numbers. But what does this mean? For instance, let’s say that one of the measures is 32 15/16, then through this process, the final number will be 32 ⅞. A simpler way to look at it is by rounding down the number to the nearest ⅛ inch. To do this, all you will need is a calculator. The results are the ones you are going to use to order all the replacements.

Ordering the new windows

This is the final step of the process and probably the most important one. Here you will have to work together with the provider and explain all the measurements. Our advice is to be patient since you need to make sure everything is in order. Another thing you need to do is investigate the average cost of the product and installation services. That way, they won’t charge you anymore. Finally, make sure they are a qualified company. Otherwise, you might lose your investment.
