Note: The span chart below is an example of how spans charts are presented. Because building code and lumber spans are updated from time to time, you should always check to make sure the span chart you are using is up to date. See the applicable code section, or the NDS to confirm the span chart you are using is correct.ĭimensional Lumber Deck Beam Spans Supporting a Single Span of Joists with or without Overhangs:Īssumes 40 psf live load, 10 psf dead load, L/360 simple span beam deflection limit, cantilever length L/180 deflection limit, No. The longer the joist, the more area of deck the joist supports, and thus the beam supports more area as well. Tables, such as those for rafters, floor joists and ceiling joists require the spacing of members to be known or selected in order to obtain the required size. Most lay outs are on 16 so the field is pre-selected. Select the on center spacing for the joists. The highest is a fully loaded floor (70 pounds per square foot). In addition, many residents prefer the fell of a deck that is designed for higher loads. The lowest is a plain ceiling joist with no storage (10 pounds per square foot). Building codes for residential decks only require 40 psf in some areas, but check your local requirements to make sure you are aware of any additional local guidelines. Beam span maximums are based on a maximum anticipated live load as well as other factors. Fewer posts on upper-level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. The other choices include spruce which is actually the spruce-pine-fir category, and the engineered I-joist.The span of a beam is dependent on a few variables: The grade and species of lumber, size of lumber and the load it carries. 2 pine is the the most common so the field is pre-selected at that. For example if a room is 10′ inside to inside and the joists are cut 10′ 7″ so they will bear fully on both walls, then the span will be 10′. This will be slightly less than the length of the board. Most lay outs are on 16″ so the field is pre-selected.

VERSA-LAM laminated veneer lumber (LVL) beams and headers eliminate twisting, shrinking and splitting, and deliver flatter, quieter floors and structures. The lowest is a plain ceiling joist with no storage (10 pounds per square foot). ENGINEERED WOOD PRODUCTS (EWP) LVL SPAN AND SIZE CHARTS. We have engineered this calculator to provide spans which will produce a solid built house with no bounce in the floors or any swags in the ceiling. The resulting spans are less than the 2012 IRC codes but they are to our standards at Scott’s Framing. The spans for joists according to the code is far more than we find acceptable.
