Rafter Cut Calculator

What is a Rafter Cut Calculator?

A rafter cut calculator is a tool or web application used to determine the length that needs to be cut from a rafter to properly fit it in a roof structure with a specific pitch and span.

It is essential for construction and carpentry projects to ensure accurate rafter cuts, which are critical for the stability and aesthetics of a roof.

Why Use a Rafter Cut Calculator?

A rafter cut calculator simplifies the process of calculating the precise length of a rafter cut, taking into account the roof span and pitch.

It ensures that roof framing is done correctly, preventing errors that could lead to structural issues and aesthetic problems in a building.

How to Use a Rafter Cut Calculator:

1. Enter the rafter span in inches.
2. Specify the roof pitch, typically in inches per foot (e.g., 6 inches per foot for a 6/12 pitch).
3. Click the "Calculate Rafter Cut" button.
4. The calculator will display the estimated rafter cut length in inches.

Example Calculation:

• Rafter Span: 120 inches
• Roof Pitch: 6 inches per foot (6/12 pitch)

Rafter Cut = (120 inches / 12) * 6 inches/foot = 60 inches

The estimated rafter cut length is 60 inches in this example.
