Pitch Of Roof Calculator

A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.

Pitch of roof calculator.

The rise is the height of the roof and the run is the horizontal span as pictured above. For example if a roof has a pitch of 4 12 then for every 12 inches the building extends horizontally it rises 4 inches. Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12.

Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. It is often compared to slope but is not exactly the same. The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

The roof pitch is the slope of the rafter.
