Rafter spans for Southern Yellow Pine, Douglas Fir, and Eastern Spruce
Rafter span tables - Use these tables to determine lengths, sizes and spacing of rafters based on a variety of factors such as, species, load, grade, spacing and pitch. Visit the roof framing page for more information on cutting roof rafters, and visit the roof pitch calculator for determining rafter lengths based on rise and run.
For example, in the rafter span table below, the highlighted cell (in the 40# Live Load table), indicates that 2' x 8' Southern Yellow Pine joists, that have a grade of #2, that are spaced 24' apart, can have a maximum span of 10 feet - 3 inches (10-3) if designing for a live load of 40 lbs/ft2.
Note: The span information in these rafter span tables is for quick reference only. Wood structural design data has been updated since this page was created. For the latest up-to-date rafter span data, please use the Span Calculator on the American Wood Council website.
