How to Measure Windows the Easy Way

Measuring windows might sound tough, but it’s not that hard when you know what to do. Whether you want to change your old windows or put in new ones, getting the measurements right is super important. In this easy guide, we’ll show you the simple steps to measure windows correctly. Let’s get started!

Easy Way to Measure Windows

Step 1: Get Your Tools

Before you start, grab these things:

  • Measuring tape: It’s like a flexible ruler.
  • Notebook and pen: You’ll write down the measurements.
  • Ladder or stool: If your windows are high up, you’ll need this to reach.

Step 2: Measure Window Width

Start by measuring how wide your window is from the inside. Here’s how:

  1. Open the window as wide as it goes.
  2. Use your measuring tape to measure from the left edge to the right edge of the window frame.
  3. Do this at the top, middle, and bottom of the window.
  4. Write down the smallest measurement. This makes sure your new window will fit, even if the frame isn’t perfect.

Step 3: Measure Window Height

Now, measure how tall your window is from the inside:

  1. Open the window wide.
  2. Use your measuring tape to measure from the top of the frame to the windowsill.
  3. Do this on the left, in the middle, and on the right.
  4. Write down the smallest measurement to make sure your new window fits just right.

Step 4: Measure Window Depth

To know how far your window sticks into your room, measure its depth:

  1. Measure from the inside of the frame to the outside. This tells you how deep the windowsill is.
  2. Write down this measurement.

Step 5: Measure Special Windows

If your window is not a regular shape, like a bay window, measure each part separately. Measure the width, height, and depth of each part just like we did before.

Step 6: Think About Curtains or Blinds

If you plan to hang curtains or blinds, measure how far from the top of the window frame you want them to hang.

Step 7: Check Your Measurements

After measuring, double-check your numbers to make sure they’re right. Being precise is super important when you’re getting new windows.


Measuring windows isn’t hard at all when you follow these simple steps. Once you’ve got the measurements down, you’ll be all set to order or install your new windows. Whether you’re doing it yourself or getting help from a pro, having the right measurements makes sure your new windows fit perfectly. So, go ahead and measure those windows like a pro!
