Most 4×6 beams are about 16 ft long, but you can get the length that meets your needs. The height of the beam will depend on the number of swings you intend to mount on it. Usually, for small cantilever beams, the span is restricted to 2 m to 3 m. But the span can be increased either by increasing the depth or using a steel or pre-stressed structural unit. The span can be constructed long, given that the structure can counteract the moments generated by the cantilever and safely transfer it to the ground. The only thing I don't know is the breaking point of the 4x6. The span is 10ft unsupported with 1ft supported at each end. The weight will be right at the middle of the span as well. I've looked all over for data on the breaking strength and even looked for my old beam calculations from engineering class. The fact that it’s called a post and there’s no span table for it as a beam pretty much tells the whole story. Ignoring the difference in strength grades and only considering the geometric properties, the 4x4 will have 26% the capacity of the 5x7 in bending and 15% the capacity of deflection of the 5x7.This is for a trellis/pergola which has 6x8 beams (how far can they span) and then 4x6 beams perpendicular on top of the 6x8 beams 6ft on center which in turn will have 3x4's 24" perpendicular on center to make the patio pergola/trellis. ...
