You merely look for the distance you need to span; match the load per foot of beam to the appropriate Fb(strength) and E(stiffness) values listed; and bang: you have a winner! Span tables are easy to use, but they have limitations. They don’t provide fine-tuned results. Most beam tables only list ... Window headers are usually built of two pieces of dimensional sawn lumber placed side-by-side. Like other pieces used in wall systems, window header thickness is limited by the depth of the wall. Most wall systems use two-by-fours, which are actually 3-1/2 inches wide. Greater strength for beams can be achieved by using thicker beams.

from Table 21 for No.1 SP lumber, select a 4-ply 2x12 beam requiring a 1.5” bearing length; from Table 24 for 24F-1.7E (V4) SP glulam, select a 3-1/2x11-1/4” beam requiring a 3.0” bearing length; from Table 26 for 24F-1.8E (V3) SP glulam, select a 3-1/8x11” beam requiring a 3.0” bearing length. There are no end joints in the runs under discussion, which joints appear first in one 2x12 at the #2 column. The lumber appears to be #1, generally free of knots. He would like to move the #1 lolly column a distance of 5'-6" so that the resulting first span would become 14'-6" with a consequential shortening of the #2 span.
