What this beam span calculator calculates
A 12 ft span with a 10 ft tributary width at 40 psf live plus 10 psf dead models 6,000 lb total load.
Formula
Clear span × tributary width × (live load + dead load) = total load; tributary width × total psf = line load.
Worked example
12 × 10 × (40 + 10) = 6,000 lb, or 500 lb/ft of line load over the 12 ft span.
Ordering decision
Point loads, bearing, connections, deflection, species, plies, and lateral restraint require a verified design.

How to use it
- Enter the measured dimensions and keep the displayed units beside each field.
- Review the beam load from span and tributary width result and the substituted formula before ordering.
- Adjust waste for the layout, cut pattern, product package, and site conditions.
- Copy or print the material list, then verify the cited product data and local requirements.
Beam load from span and tributary width
Use this beam calculator for a preliminary uniform-load check. It turns clear span, tributary width, live load, and dead load into line load and total modeled load without pretending to select a beam size.
Limits and professional review
Measurements, product yield, waste, moisture, and site conditions can change the order quantity. Local code and a licensed professional govern structural and electrical work.
