About Roof Pitch Tool

Roof Pitch Tool is a focused online calculator created by xiaojie xu, an individual maker. It helps people convert matching rise and run measurements into a roof pitch ratio, roof angle, slope percentage, and rafter factor.

The calculator is designed to be quick to use on a phone or computer. Calculations run in the browser, and the site does not require an account or save a history of entries.

Roof Pitch Tool provides geometry calculations for planning and reference. It does not replace advice from a qualified professional, local building requirements, or manufacturer instructions.
