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.

How far can you span a 2 x 10 floor joist?

2×10 floor joists can span up to 20’. However, this is for 12” o.c. spacing for live loads that are 30 psf. This is unrealistic because any living space or deck requires a joist that can support a 40 psf live load. Otherwise, the joists are not to code.

How much weight can a 2x10 beam support?

How much weight can 2x10 floor joists hold? In fact, each 2x10 will support 1,200 lbs. To be clear, spans are measured as "clear spans". Just so, how much weight can a floor joist hold?

What is a span table?

Span tables are intended to give builders information about the appropriate size of dimensional lumber to use when constructing in certain places. A span table will, therefore, tell you the appropriate length of 2×10 to use to ensure your size of the deck, beam, or joist will support a 40 psf live load on a deck.

What is a 2x10 rafter?

A 2×10 beam, joist, or rafter is merely a part of a larger picture. While we can use span tables and calculators to determine the distance a piece of lumber can bridge before it needs more support, we also need to account for all factors that might affect that piece of wood.
