Ridge beam calculator
A structural ridge beam carries half the roof load delivered by the rafters as a series of point loads or an equivalent UDL. Set the span between the ridge supports, add the rafter reactions, and check the maximum moment and deflection against your design limits. The calculator below is pre-loaded; change anything and results update instantly.
About this case
Two supports with an overhang past the right support.
All diagrams use the Euler–Bernoulli beam theory with an exact finite-element solver that runs entirely in your browser. You can move supports by dragging them, switch unit systems at the top of the input panel, and export results as CSV or a printable report.
