It looks the the rafter span would be just over 19 feet which I thing would really be pushing the limits. The most common way to specify a beam size is by its depth and weight per foot. For example, a "W8x10" beam is 8 inches deep and weighs 10 pounds per foot. The standard sizes for beams are determined by a number of factors, including the anticipated load-bearing requirements, span length, and engineering calculations.

The lengths typically run from 4′ to 48′, with increments of 4′ available.

So the roof load might be 35 PSF. Using that 16x16=256 x 35 = 8960 lbs roof load. Half (4480) will be supported by the ridge beam. Using 4480 pounds evenly distributed along the beam along with the values for DF I came up with some results for building the beam from standard dimensional lumber; the DF #2.Without rafter ties, the ridge sags onwards, and the top of the walls supporting the lower ends of the rafters push or “kick” outward.
