Sizing a ridge beam
The ridge board is always full depth of cut rafters unless a low pitch(<3/12), then designed as beams. 1x boards "ok", check local code.

Once I determined the loads, I sized and priced the beams that are required to carry the loads.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.
