Estimate the allowable uniform load on an LVL beam, or back-calculate the maximum span for your load. Use it to size headers and beams before talking to an engineer.
Uses section modulus, allowable bending stress, and a L/360 deflection check.
Check if your span works, or see the maximum span your beam can handle.
Common for load-bearing headers over doors and windows and garage beams.
Estimates only — always verify with an engineer or manufacturer tables.
Build it right the first time.
