Frequently Asked Questions
Common questions about Wood Joist Span Table, formulas, and expected usage.
What loads are these span values based on?
These values are typical references based on common residential assumptions around 40 psf live load and 10 psf dead load.
Why does spacing change allowable span?
Wider on-center spacing means each joist supports more floor area, which reduces allowable span for a given size and species.
Can I use this instead of local building code tables?
Use this as a planning tool only. Final joist spans must follow your local code, species grade stamp, and project loading conditions.
Why are species groups separated?
Different wood species have different strength and stiffness properties, so allowable spans differ even with the same joist size.
