分步代入计算过程

01Canonical Law: R = √(run² + rise²)

02Given Inputs (Base Units): run = 6 m, rise = 3 m

03Solve for R (Common Rafter Sloped Length): R = 6.7082 m

Common rafter framing forms a right triangle over horizontal half-span run and vertical ridge rise, giving sloped rafter length R = √(run² + rise²) and roof pitch (rise / run) × 12.

常见参考标准值

6:12 Standard Gable PitchRise = 0.5 × Run (26.57° Angle)

Rafter multiplier = √(1 + 0.5²) = 1.1180× run

4:12 Minimum Asphalt Shingle PitchRise = 0.333 × Run (18.43°)

Minimum slope for standard shingle shedding without membrane

12:12 Steep Architectural PitchRise = 1.0 × Run (45.00°)

Rafter multiplier = √2 = 1.4142× run
