Wiring a 3 way switch

I have a standard light switch at the corner of a shed and would like to change the wiring so I can turn on the lights from another corner of the shed. Do I need two or three wires for this new switch location and what is the minimum size wire?

Hi, a 3 wire ,wire size will depend on the over current protection for the circuit, 15 amps #14. 20 Amps #12.
