Working out required track width

[Rajinder]

Hi all
I have a question regarding PCB track width.
If i have 1oz copper. I have an external EEPROM connected to my PIC micro via I2C interface. How do i obtain the correct track width and length. I have positioned the EEPROM clise to the PIC to minimise track length. I am using Eagle PCB.

On the same PCB i have mains to power the PCB. Again please could you advise on track width but also ideas on creepage and clearance.

Thanks.
