What is the rafter length for a 4/12 pitch | Rafter length for a 4/12 roof Pitch

@HelloSirJi What is the rafter length for a 4/12 pitch | Rafter length for a 4/12 roof Pitch.

To calculate the rafter length for a 4/12 pitch roof, you'll need to use the Pythagorean theorem. For a 4/12 pitch, the rise (vertical distance) for every 12 inches of run (horizontal distance) is 4 inches. So, the slope length (hypotenuse of the triangle formed by the rafter) can be found using the formula: rafter length = √(rise² + run²).

Given the rise is 4 inches and the run is 12 inches, the calculation would be: Slope length = √(4² + 12²) = √(16 + 144) = √160 ≈ 12.65 inches, or 1.054 feet.

So, the rafter length for a 4/12 pitch roof would be approximately 12.65 inches or 1.054 feet
