Roof Truss Height Calculator
This calculator determines the height of a roof truss based on its total span and roof pitch. By entering the width of the structure (span) and the pitch as a rise over 12, the tool calculates the peak height of the truss. This is useful when designing gable roofs, estimating attic space, or checking compliance with height restrictions in building codes.
For calculating full rafter length using span and pitch, use the
Common Rafter Length Calculator.
To convert roof pitch into angle or slope percentage, see the
Roof Pitch to Angle Calculator.
Looking to estimate roofing materials for a hip roof? The
Hip Roof Square Footage Calculator provides ridge length, roof angle, and area in ft²
Height of Truss
Calculator
- building width
- slope in inches per foot
- truss heel height
Results
- total roof truss height from base to peak in inches
