Joists are available in several depths and lengths and superior strength allows them to span up to 30 feet (TRIFORCE span tables).
What is the maximum span for floor joists?
The maximum span of a 2×8 floor joist depends on several factors, including the wood species, grade, spacing between joists, and the expected load. In general, for residential construction using standard framing lumber such as Douglas Fir-Larch, a joist can span approximately 10 to 13 feet when spaced 16 inches apart.

What is the maximum span for a 2×6 floor joist?
For example, a 2×6 joist would have a 12-foot, 6-inch maximum span, and a 2×10 joist would have a 21-foot maximum span. Additionally, wood species and grading determines how far apart floor joists can be spaced.
What is the maximum cantilever for floor joists?
For wood joists, the maximum allowable cantilever is limited to not more than one-fourth of the actual joist backspan. Additionally, the maximum cantilever is based on the bending strength (deflection) of the joist evaluated with a 220-pound point load placed at the end of the cantilever.
The joist are usually placed at a centre to centre distance of 300mm to 450mm. the joist are supported on wall-plates at their ends. A space of about 50mmis kept fr the circulation of air as shown in fig. the single joist timber floor can be adopted for a maximum span of about 3.60m.

At Carlisle, we recommend engineered wood as the best flooring for basement installation. Engineered wood is made with a top layer of hardwood – called the “wear layer” – that’s adhered to multiple layers of backing material, creating a floorboard that’s less affected by changes in temperature and relative humidity.
