Roof beam span calculator
Lastly, multiply the number of rafters by 2 to get both sides of the roof or the roof’s slopes. For example, your house is 40 feet long with a 24″ rafter spacing. So the first thing you need to do is convert 30 ft to inches. 40ft x 12″ = 480″ (length in inches) ÷ 24″ on-center = 20 rafters.
Thus, a triple 2×8 deck beam can span maximum distance of 10-11 feet. How far can a triple 2×10 beam span.
