What is the maximum span for a 2x10 floor joist?
With 16” spacing, a floor joist can span up to 14’ as long as it is not cantilevered and terminates with support on either end. If the joists are 24” apart, then one 2×10 joist can span up to 11’ 5”. These lengths are for SYP lumber. If you have Spruce-pine-fir lumber, then your span changes to 13’ 7” for 16” joist spacing.

What are the best ways to calculate joist spacing?
Joist spacing is commonly given as “on center” (o.c.), which means the spacing is measured from the center of one joist to the center of the next one. The most common joist spacings are 12, 16, and 24 inches on center. Watch out: nobody with any sense actually lays out joists by measuring to their center.
What is the maximum span of an I-joist?
Span refers to the length of the I-joist. The L/480 table with a 40 per square foot live load and a 20 per square foot dead load with a depth of 11 7/8 inches will give you spans according to joint weight. With these factors, the lightest joist will have a maximum span of 17 feet, 8 inches.
