Truss Span Tables And Details
Are there any typical wood truss span tables for roofs and floors available? Standard framing details for use in preliminary design?
You can use SBCA’s span charts to roughly determine truss sizes available. Included are a series of representative roof truss span tables that will give you an idea of the truss spans available for a particular load condition, load duration, lumber type, and truss configuration.
Keep in mind that these tables are for estimations only. They have not been updated for the change in lumber values within the last decade. We recommend checking with a truss designer first to see if the truss in question is viable. Download some standard truss framing details.
