Typical standard the typical standard for the spacing on the roof trusses is 24 inches. Most economical when the difference in slope between the top and bottom chords is at least 3 12 or the bottom chord pitch is no more than half the top chord pitch.

Just keep in mind that if the length of the board size is more than 20 feet then you need to use a more expensive type of lvl board and not a traditional pine board for this longer length. These standards are as follows. Engineers have since determined however that the physical design of a post frame building will allow for standard spacing as great as 12 feet from the center when using high quality metal connector plates and lumber. Their defense is our engineers will not allow us to.

Roof trusses were usually produced on site in the past. For instance if you are spacing your trusses 18 inches apart make a mark 18 inches from the edge. Flat the most economical flat truss for a roof is provided when the depth of the truss in inches is approximately equal to 7 of the span in inches. With this design change roof trusses could be placed 12 feet apart making it possible for roofs to support the loads to which they would be subjected.
