In general there are only 2 standard socket sizes, 13/16 and 5/8. A true spark plug socket will have a little rubber gasket inside to prevent the plug from slipping out during removal/replacement. You could technically use any proper size deep well socket though.
So, try a 5/8, if it is too small then try a 13/16. I would say that if you don't own those two sizes then maybe changing your own plugs is not the best idea for you.

Do you have 60,000 miles yet. I'm all for changing plugs a little early. Car has only been out a little over a year. Be carefully of what plug you use.
