Calculator guide
Roof Pitch Angle Converter helps you explore the stated conversion question. Start with the labelled inputs, then review the method, worked example and limitations before using a result.
Formula or method
Pitch ratio = rise÷run. Roof angle = arctan(rise÷run); convert radians to degrees for the angle display.
How to use this calculator
- Enter the rise and run or angle in the selected mode.
- Read pitch and degrees as different descriptions of the same slope.
Worked example
A 6-in-12 pitch has ratio 0.5 and angle arctan(0.5) ≈ 26.565°.
Understanding the result
Compare the output with the roof pitch angle converter worked example using exactly the same inputs. A different assumption or rounding convention can produce a different displayed result; the output does not establish personal or professional suitability.
Limitations and assumptions
- Measure rise and run in the same units. Pitch conversion does not assess framing loads or roofing suitability.
- The worked example demonstrates the stated assumptions, not a recommendation about your personal circumstances.
Frequently asked questions
Which inputs should I check first?
Follow the Roof Pitch Angle Converter input instructions above. Check each measurement, date, selection or expression before comparing results.
Why might my result differ from another tool?
Compare the other tool's roof pitch angle converter method, input units, rounding and assumptions. A matching title does not guarantee that both tools answer the same question.
Does a linked reference certify this result?
No. A reference can explain a formula or provide background for Roof Pitch Angle Converter, but it does not endorse this website, validate personal inputs or establish professional suitability.
