Horizontal distance from the eaves to the ridge – for a gable roof, half the building width.

Roof pitch

26.57°

26.57°

With 3 m height over 6 m depth, the roof has a pitch of 26.57° (50%). The rafter is 6.71 m long.

How this was calculated
α = arctan(3 ÷ 6) = 26.57°
Pitch = 3 ÷ 6 × 100 = 50%
Rafter = √(3² + 6²) = 6.71 m

Height and depth form a right triangle: the angle at the eaves is the roof pitch, the slope is the rafter (without overhang).
