The roof will have a 3 12 slope to match my garage. There is no standard spacing it depends on what size of rafters you want to use and the span of your shed. The ridge end of the rafter and often the eve end will need to be cut to the angle of the roof slope. Build gables suspend ridge board install 2x6 rafters w proper birds mouths.

A stick framed roof uses 2x4 s or 2x6 s or whatever you are framing with but has a ridge board running down the middle ridge line.

Will 2x4 rafters 24 inch on centre hold up my 8 x 12 shed. I think you are overthinking it. Sometimes the rafter will have a tail and extend out past the wall so that you have a soffit or overhang. For instance 2 grade 2x4s at 16 on center will span just over 9.
