Load Capacity Calculator | Free Construction Calculators

Calculate the safe load capacity for joists or beams based on size, span, and lumber properties.

About Load Capacity

This calculator determines the safe load capacity for structural members considering both bending strength and deflection limits. Results include total load capacity and recommended live and dead loads.

Safety Warning

Load capacity calculations are critical for structural safety. Always verify results with local building codes and consult a licensed structural engineer for load-bearing applications.
