Replacing windows in your home can be a significant investment, so it’s important to get accurate measurements before you buy. Measuring for replacement windows is a relatively straightforward process, but there are a few things you need to keep in mind to ensure a proper fit. In this article, we’ll walk you through the steps on how to measure for replacement windows, so you can be confident that your new windows will fit perfectly.
First, you’ll need to determine the type of window you have. There are three main types of windows: single-hung, double-hung, and casement. Single-hung windows have one operable sash that slides up and down, while double-hung windows have two operable sashes that slide up and down. Casement windows have a single sash that swings open on hinges. Once you know the type of window you have, you can start taking measurements.
To measure for a replacement window, you’ll need to measure the width, height, and depth of the existing window frame. The width is measured from the outside edge of the left frame to the outside edge of the right frame. The height is measured from the top of the frame to the bottom of the frame. The depth is measured from the inside edge of the frame to the outside edge of the frame. Once you have these measurements, you can start shopping for replacement windows.
Measuring the Width of Your Window
1. **Measure from the exterior.** This is the most accurate method, as it eliminates any variance caused by interior trim. Stand outside your home and use a tape measure to measure the width of the window frame, from the leftmost point to the rightmost point. Make sure to measure only the frame, not the glass or the surrounding wall.
2. **Measure from the interior.** If you can’t measure from the exterior, you can measure from the interior instead. However, this method is less accurate because it can be difficult to account for the thickness of the interior trim. To measure from the interior, open the window and measure the width of the window frame, from the inside edge of the left jamb to the inside edge of the right jamb.
3. **Check for squareness.** Once you have measured the width of the window, check to make sure that the window is square. To do this, measure the diagonal distance from the top left corner of the window frame to the bottom right corner, and then from the top right corner to the bottom left corner. The two measurements should be equal within 1/8 inch.
4. **Record your measurements.** Once you have measured the width of the window and checked for squareness, record your measurements in a safe place. You will need these measurements when you order your replacement windows.
| Measurement | Value |
|---|---|
| Width (exterior) | [measurement in inches] |
| Width (interior) | [measurement in inches] |
| Diagonal distance (top left to bottom right) | [measurement in inches] |
| Diagonal distance (top right to bottom left) | [measurement in inches] |
Measuring the Height of Your Window
To accurately measure the height of your window, follow these steps:
1. Measure the Distance from the Sill to the Top of the Window Casing
With a measuring tape, measure from the top of the window sill (the horizontal support at the bottom of the window) to the top of the window casing (the frame that surrounds the window).
2. Measure the Distance from the Sill to the Top of the Window Glass
Next, measure from the top of the window sill to the top edge of the window glass.
3. Determine the Height of the Window Frame
Determine the height of the window frame by subtracting the height of the window glass from the height of the window casing. This measurement represents the thickness of the window frame, which is essential for ordering the correct replacement windows.
| Measurement | Description |
|---|---|
| Height from Sill to Casing | Measurement between the top of the sill and the top of the window casing |
| Height from Sill to Glass | Measurement between the top of the sill and the top of the window glass |
| Frame Height | Height from Sill to Casing minus Height from Sill to Glass |
| Measurement | Method |
|---|---|
| Height | Measure from the top to the bottom of the window frame on both sides. |
| Width | Measure from the left to the right of the window frame on both sides. |
| Squareness | Use a level to check if the window frame is square. Measure the diagonals from corner to corner. |
| Obstructions | Check for any obstructions, such as nails or screws, that may interfere with the installation of the new window. |
Determining the Type of Replacement Window You Need
1. Consider Your Style and Home’s Architecture
Choose a window style that complements your home’s exterior and your aesthetic preferences. Options include casement, double-hung, awning, and bay windows.
2. Assess Energy Efficiency
Look for windows with a high Energy Star rating. Consider double-paned or triple-paned glass, low-E coatings, and insulated frames to minimize heat loss and gain.

How To Measure For Replacement Windows
Measuring for replacement windows is a crucial step to ensure a perfect fit and optimal performance. By following these precise steps, homeowners can ensure accurate measurements and a hassle-free installation process:
- Measure the Width: Use a measuring tape to measure the width of the existing window frame, from outside edge to outside edge. Record this measurement as the “width.”
- Measure the Height: Measure the height of the window frame, from the top of the frame to the bottom of the frame, including any trim. Record this measurement as the “height.”
- Measure the Diagonal: Measure the diagonal distance from one corner of the window frame to the opposite corner. This measurement should be taken twice, once from each diagonal. If the two diagonal measurements are not equal, the window frame is not square and you will need to take additional measurements to determine the exact shape.
- Note any Obstructions: Inspect the window opening carefully for any obstructions, such as window sills, molding, or trim. Make note of these obstructions and include them in your measurements.
- Consider Window Style: Depending on the style of replacement window you choose, you may need to take additional measurements. For example, if you are replacing a casement window, you will need to measure the height and width of the window sash.
Once you have completed these measurements, you will have all the necessary information to order replacement windows that fit your home perfectly.
