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.A 2×8 will support a dead load of 20psf and a live load of 40psf resulting in a total load of 60psf.

You should be OK for just about any decent structural timbers.Answer: One needs to use a typical formula for measuring the sizes, which can be read as follow. The formula one can read is beaming width x beam depth raised to the power 2 and divided by a 6 factor. For example, a 2 x 6 beam that has the dimension of 1.5 x 5.5 inches can give a section modulus of 1.5 x 5.5. x 5.5 / 6 = 7.6. Beam Span Chart Table. SHARE.
