Use the Pythagorean theorem to calculate the length of the truss's individual components; for instance, the hypotenuse (rafters) lengths depend on the span and rise. Consult engineering tables or a truss calculator for precise measurements of webbing components—the internal struts that provide structural support.

A parallel chord vaulted truss is a type of roof truss that has sloping top chords and parallel bottom chords. This creates a vaulted interior space that is taller at the center than at the edges. Parallel chord vaulted trusses are often used in homes and commercial buildings. The Parallel Chord Vaulted Truss is configurable in a range of sizes with typical spans between 24'-72' (7.3-21.9 ...

To determine how many trusses to create, you will first need to measure both the width and the length of the structure you are building. The trusses should be a little longer than the exact width to allow for overhang, and you will need sufficient trusses to mount across the length.
