How far should my feet be spread apart?

I've noticed watching videos of pro surfers, the distance between the two foots is fairly spaced apart. On the other hand, my stance is not so spread.
Should I train myself to spread my feet apart further?
I'm riding a 7"2 shortboard and started 2 months ago.
