How large can you make a truss? Maximum length is 80′ + up to 24′′ overhangs . Maximum truss height we can build is 13′ – 10′′ from peak to bottom of overhang, however, due to shipping constraints, we prefer to keep the truss height under 12′.
How big can trusses be?
Trusses can span up to approximately 90′ , although very long truss spans are more challenging to deliver, erect, brace and install properly. While longer trusses may be “wobbly” as they are lifted off of the ground and onto the bearing walls, once they are properly braced, the truss system is extremely strong.

Are roof trusses 2×4 or 2×6?
Trusses only use 2×4 lumber and are constructed using a “web” of 2x4s for strength. Rafters simply rely on a center ridge beam and the outside walls for support. While there are benefits to both, only rafters vary in the size of lumber that is used.
Is it cheaper to build your own trusses?

Are two 2×4 as strong as a 2×8?
Your statement about 2- 2×4 not being as strong as one 2×8 or one 2×10 is technically correct because the height is different for each one (not apples to apples). Referring to the code tables is a little misleading. Double stacked beams (not glued together) each carry half the load.
How far can a 2×6 decking span without support?
Decking Board Considerations
