2x10 Vs 2x12 Strength, 2x12 joists Best for: Clear spans less than 17' when joists are spaced 16" on center, or clear spans less than 19' when joists are spaced 12" on center. 2x10 vs 2x12 for stair stringers: how throat depth after notching affects strength, when a 2x10 is enough, and why most stairs use 2x12 stringer stock. Determine Maximum Joist and Rafter Spans Nov 20, 2015 · Based on a roofing rafter span table the 8-9' span of the glazed south wall is easily supported by 2x6 lumber on a 24" center. Rafter Span Tables Calculating Maximum Rafter Spans Rafter Span Tables - Use these tables to determine lengths, sizes, and spacing of rafters based on several factors such as species, load, grade, and spacing. Joist Span Table - Use this table to determine floor joist spans, deck joist span, and floor joist spacing. 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. 2x8 would do it with plenty of room to spare, Can anyone point me to a comparable strength steel tube or aluminum tube?. Thanks for visiting the MSRLPC Design Values Comparison Tool. Nov 23, 2021 · * Please note: This equivalency chart is intended to provide a reference to similar strength / performance characteristics by respective manufacturers per current (04/2017) regional specifier guides. Please select a species using the form below to compare machine stress rated lumber reference design values with visually graded dimensional lumber. Calculator generates the maximum span distance as well as the bending strength (F b), shear strength (F v) and bearing strength (F cp) values for each Stamp selected. Repeat until desired number of Stamps have been added. After this length of span, engineered beams or headers would need to be designed by a professional engineer to ensure safety and adequate structural support. ), and spacing (how far apart the joists are). Joists & Rafters Southern Pine Joists and Rafters Span Tables Southern Pine has long been a preferred species for building construction because of its treatability, strength, and fastener-holding power. Learn when to use 2x6, 2x10, or 2x12 based on spans, loads, and IRC code requirements. Calculators are for use in U. Span Options Calculator For Wood Joists And Rafters offers a tool to assist with wood design calculations based on codes and standards. SFPA offers nearly 100 span tables for treated Southern Pine lumber, joists and rafters, and headers and beams. Span Tables Use the span tables in the links below to determine the maximum allowable lengths of joists and rafters. Learn to size joists and rafters with AWC span tables; this tutorial covers load combinations, deflection limits and using tables for safe design. Southern Pine dimension lumber is readily available in wide widths, making it ideal for joists and rafters. 25 inches wide, a 2x10 nominally 9. would be 15 feet out from the house and 21 feet wide. applications only. For Canada switch to Canada Sizing Table Lookup. Ensure a rock-solid floor today! The largest deck you could build with a triple 2x10 flush beam, 3 posts, and 2x10 joists spaced 16" O. C. These tables provide maximum spans for the #2 grades of four common species of lumber (Southern Pine, Douglas Fir, Hem-fir, and Spruce-pine-fir (SPF). S. Understand the engineering factors and building codes that mandate the right choice. A joist span table tells you the maximum distance a floor joist can span between supports without exceeding code limits for deflection and strength. Enter lumber size, type of use, and span requirements in the Design Criteria section. May 11, 2026 · Master floor joist selection. 25 inches wide, so the difference in strength is naively 21 percent. An 8 foot opening would require a doubled up 2X10 and a 10 foot opening, a doubled up 2X12. The span depends on four variables: wood species (determines strength and stiffness), lumber grade (#1 vs #2), joist size (2x8, 2x10, etc. It isn't that simple, though, because the probability of a defect (knot, check, or split) gets higher as the plank gets wider. Dec 1, 2025 · The size of your stair stringers (2×10 vs 2×12) is critical for safety. Mar 15, 2026 · Learn how span, spacing, wood species, and load requirements determine whether your floor needs 2×6, 2×10, or 2×12 joists.
