Window Rough Opening Calculator

What is a Window Rough Opening Calculator?

A Window Rough Opening Calculator is a tool used to determine the rough opening dimensions required to install a window in a wall.

It considers the size of the window frame and the clear opening dimensions needed for the window to fit correctly.

Why Use a Window Rough Opening Calculator?

This calculator is valuable for builders, contractors, and homeowners to ensure that the rough opening in the wall is properly sized for the window that will be installed.

It helps avoid issues like a window frame that is too small or too large for the chosen window.

How to Use a Window Rough Opening Calculator:

1. Enter the width and height of the window frame (in inches).
2. Specify the clear opening width and height (in inches) required for the window.
3. Click the "Calculate Rough Opening" button.
4. The calculator will display the required rough opening dimensions in inches.

Example Calculation:

• Window Frame Width: 36 inches
• Window Frame Height: 48 inches
• Clear Opening Width: 34 inches
• Clear Opening Height: 46 inches

Required Rough Opening Dimensions:

• Width: 36 inches + (34 inches - 36 inches) = 34 inches
• Height: 48 inches + (46 inches - 48 inches) = 46 inches

In this example, to install a window with a frame width of 36 inches and a frame height of 48 inches, the required rough opening dimensions are 34 inches in width and 46 inches in height.

These dimensions ensure that the window fits properly within the wall.
