How to Measure Old Wood Windows for Replacement

From understanding measurements of window frame widths and heights, adjusting for standard allowances like locks or handles that protrude from the sides, and even double-checking specific jamb depths – we have everything you need to know about precisely measuring old wooden windows and getting them replaced with ease. Read on for all the details of how to measure old wood windows for replacement.

Why the Right Measurement is the Key?

1. To Avoid Mistake

When it comes to replacing windows, getting the right measurements is essential for ensuring a successful installation. Incorrectly measured windows can not only be difficult to install and result in costly mistakes but also create gaps or small spaces that may allow air leakage or even water damage.

To ensure the correct window size is ordered for replacement, measuring accurately becomes especially important.

2. To Ensure a Seamless Look During Installation

Faulty measurements can also result in window frames that either stand out or are too flush with the existing wall space, which can create an unsightly look during installation. Therefore it is important to properly measure your old windows so your new ones will fit seamlessly into the existing space without any gaps.

Required Items for Measuring

Before you get started, you will need the following items to measure your old wood windows:

  • Tape measure
  • Pen or pencil
  • Notepad/paper
  • Leveler (optional)
  • Calculator (optional)

How to Measure Old Wood Windows for Replacement in 10 Ways

Now that you know why it’s important to get the right measurements, let’s go over how to properly measure your old wooden windows so you can order the correct size replacements.

Use a Tape Measure

1. Determine the Width of the Window Frame

The first step is to measure the width of your existing window frame. Before measuring, make sure that all inner and outer shutters are closed and opened completely so you can get accurate measurements. Then use a tape measure or ruler and run it along the top inside edge of the window’s frame from one side to another. Make sure not to press down too hard against the wood, as this can result in inaccurate measurements.

2. Determine the Height of the Window Frame

To determine the height of the window frame, measure from the top inside edge to the bottom inside edge and record your findings. Just like with width, make sure not to press down too hard against the wood while measuring, as this can give you false readings.

3. Measure Window Frame Depth

Once you have the width and height of your window frame, it’s time to measure the depth. To do this, place the end of your tape measure or ruler against one side wall of the window frame and then extend it until it reaches the opposite wall. Record that number as well.

4. Adjust for Locks or Handles

If your window has locks or handles that protrude from the sides, you will need to adjust the width of your measurements accordingly. Simply deduct 1/8” (3.175mm) for each side per lock and handle respectively. This should be taken into account when you’re ordering new replacements.

5. Measure Window Sill Depth

The next step is to measure the depth of your window sill. To do this, place your tape measure or ruler against the front edge of the window sill and then extend it until it hits the back edge. Record that number as well.

6. Double-Check Jamb Depths

Now that you have the width, height, and depth of your window frame as well as the depth of your window sill, it’s time to double-check the jamb depths. To do this, measure from the front edge of the window frame down to the top edge of your window sill. This number should equal what you previously measured for the depth of your windowsill.

7. Check for Height Variance

Another important step when measuring old wooden windows is to check for height variance, especially if your window has multiple panes of glass or if it’s arched. To do this, measure from the top inside edge of the frame to the bottom inside edge at each corner of the window and make sure each number is consistent.

8. Record Measurements

Once you’ve completed measuring your old wooden windows, take a moment to record all of your measurements on paper or in an electronic notepad. This will ensure that you have everything written down correctly and make it easy to order the correct size window replacements when the time comes.

9. Measure Twice for Accuracy

It’s also important to measure twice for accuracy. This means taking your measurements again after your initial set of measurements just to make sure everything is correct and consistent. Taking the time to double-check your numbers can save you a lot of time and money in the long run.

10. Choose the Right Replacement

Finally, make sure to choose the right replacement window styles for your home. Whether it’s double hung or casement windows, there are plenty of options available that can match your existing look while providing added energy efficiency and other benefits.

With these tips in mind, you should now have all the information you need on how to measure old wood windows for replacement.
