⚠️ Engineering Disclaimer
This calculator provides preliminary estimates only and should not be used for final structural design. Actual beam sizing requires consideration of: lumber grade and species, load duration factors, wet service conditions, stability and lateral support, bearing conditions, and local building codes. Always have structural calculations verified by a licensed professional engineer before construction.
