How far can a 4x6 beam span without support.

I did a partial post and beam house and there were three areas that had support beams. The longest spanned 34 feet and I was told I would need an engineered beam 5" by 27" and laminated. The next spanned 23 feet, and it was 3" by 18". The last ones were all 8 foot span, and I was using 3" by 12" solid fir. Deck joists are generally 6, 8, 10, or 12 inches in width, with 8 or 10 inches as the most common sizes. Deck joists come in dimensional lumber lengths from 8 to 16 feet. As discussed in this article, deck joist span is important for designing decks to support heavy loads. Deck joist spans depend primarily on how much weight the deck will bear.All the tables for Headers and Beams have clear span for sistered or built-up beams.
