Roof pitch varies depending on culture climate style and available materials. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Roof pitch refers to the slope which the rafter creates. A simple angle calculator for right angled triangles.

In us instead of the whole run 12 inch is used and the pitch is how much rise or fall is for 12 inch of run. Pitch is expressed as a degree or percentage in countries that use the metric system while in countries that use imperial measurement pitch is expressed with rise first and run second.
