Learn everything you need to know about floor joist spans . This guide discusses floor joist spans , along with sizing, span tables, and types of wood.
What Is Floor Joist Span and Spacing? Floor joists are supporting members used in building floors that span over an open space and between load-bearing walls and structural beams. They are placed parallel and equidistant to each other, and connect to vertical members like studs and support beams which distribute weight across the rest of the ...

Floor Joist Span Table 2x6, 2x8, 2x10, 2x12 Spans by Species ...
A joist span table tells you the maximum distance a floor joist can span between supports without exceeding code limits for deflection and strength. The span depends on four variables: wood species (determines strength and stiffness), lumber grade (#1 vs #2), joist size (2x8, 2x10, etc.), and spacing (how far apart the joists are).
A floor joist is a horizontal structural framing member that spans the open space between foundation walls, beams, or load-bearing walls. Floor joists are installed on edge (standing tall rather than laying flat) and run parallel to each other at regular intervals.

A floor joist span is the horizontal distance a joist can safely bridge between supports without excessive deflection or structural failure. The IRC (International Residential Code) publishes span tables in Section R502.3.1 that specify maximum spans based on lumber size, species, grade, spacing, and the design loads the floor must carry. Floor joist spans are calculated for two load ...
