dimensional lumber floor joists 2 x 8, 2 x 10, and 2 x 12 construction lumber was the popular choice for floor joists before floor trusses and i-joists were developed. though construction lumber cannot span as far as floor trusses or i-joists, it is readily available, and when used within its strength capabilities, construction lumber will produce a solid-feeling floor system.
floor truss span chart each individual floor truss design is unique based on multiple variables: geometry, loading, spacing, bearing conditions, etc. span tables below illustrate common combinations of the multiple variables available.
floor truss spans can vary depending on floor truss depth and the spacing of floor trusses. our floor truss span chart helps you to determine the correct depth and spacing required for your next floor truss project.
