Usually you have to Use 1 mm trace for 1 Amp of current for 35 micron of copper thickness (on pcb material).If you have constrains on pcb,you can reduce the trace width to 0.5 mm by using 70 micron.You may have to open solder mask the reace if required.
Mantain creepage of 4 mm between power trace & any other signal & ground in primary section. For secondary section 0.5mm clearence is enough.
Hope this helps you.
Have a nice day
