LEADWORX TOOLS

Roof pitch calculator

Calculate from measurements, or estimate the angle from a photograph.

Rise & run

Measure the vertical rise and horizontal run between the same two points.

Horizontal run Rise Roof slope Pitch

Use the same unit for both, such as mm or cm. Run is not the sloping roof length or automatically the full building width.

Enter your measurements to begin.

Calculated roof pitch—degrees from horizontal
Other pitch formats

Enter measurements first.

These formats describe the same slope; they are not product size recommendations.

Check the pitch before ordering made-to-measure leadwork. Measure only from a safe, accessible position.
