    So, if you’re wondering how far a 2×10 can span, we’re here to help. A #2-2×10 joist can span between 11’-5” and 18’-0”, as a rafter between 13’-9” and 21’-7”, and as a beam 3’-6” and 13’-0” or more. The span depends on spacing, lumber species, and grade, and for a beam, the lamination thickness, as well as numerous other factors.

    A 2×10 beam – made up of two 2x10s nailed together – can span up to 11’ without support beneath a deck that is 4’ wide. For a more normal-sized deck, the same beam can span 8’, supporting a deck that is 8’ wide. You can also triple a 2×10 beam.

    Typically a #2-SYP 2×10 triple deck beam can allow to span a maximum distance from 12 to 13 feet with a total load of 50 psf (40 psf live load + 10 psf dead load) with a deflection limit of L/360. So, a triple 2×10 deck beam can span maximum distance of 12 to 13 feet.
