Answer
Primary Coil is made thicker than the secondary coil in a step up transformer. As current in primary coil is more than in the secondary coil so the wire in the primary coil is kept thicker.
The use of thicker wire in a coil reduces it's resistance and therefore, reduces the loss of energy as heat in that coil.
