This rafter truss calculator has a range of applications including being used as a wood truss calculator roof truss calculator roof rafter calculator scissor truss calculator or for roof framing.
Roof truss angle finder.
The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r.
No fooling around with tape measures and levels.
This free online truss and roof calculator generates the axial forces and reactions of completely customisable 2d truss structures.
Recalculate this value into an angle.
Simply set it on your roof or the underside of a rafter and read the gauge.
Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results.
