This is a useful reference.
The CircuitCalculator.com Blog PCB Trace Width Calculator
There's other stuff that might be helpful on that site including a calculor to give you the thermal resistance of different sizes and plating thickness of via holes. It proved very useful for me when I had to design a board with surface-mount power transistors on one side, but the heatsink was fitted on the other side of the pcb. Multiple thermal vias from the transistor pads on one side, to similar pads on the other, (which then passed the heat to the heatsink/radiator) worked very well indeed.
