picasm Member Jul 23, 2007 #4 There are a few calculators online and sometimes also built-in to pcb design software, here is an online one: https://www.desmith.net/NMdS/Electronics/TraceWidth.html Note that you need to know the thickness of the copper layer and must also allow plenty of clearance between tracks for high voltages to prevent immediate problems and also prevent "creepage" as the board ages,humidity etc.
