I am presently building a open shelter for my mill and need to size the timbers for use in headers. If you are going for a large joist span, use a 50lb. Bearing Length, in. There will be a walk in door next to the house, and then a 16 foot garage door. For the initial calculation, F can be estimated at 1,000. The wall load is assumed to be 100 plf (pounds per lineal foot) dead load. Residential Code 2015 of Utah > 8 Roof-Ceiling Construction > R802 Wood Roof Framing > R802. Select the span carried by the header across the top of the table. If you are going to build a small bridge that spans perhaps 8 feet or less, I would use 2x8's that are placed 16 inches on center.
