To do what? Highest attitude, longest flight time by recovery
by parachute or streamer, closest distance between the launching
pad and the landing point or some other type of activity that
you have planned for these flights.

There was section on this in the 1994 Estes catalog. According
to it the size of the fins were a relation to the width of the
body tube. It was recommend that the root edge (edge connected
to the body tube) side be 2 times the diameter of the body tube,
the opposite side of root edge be 1 diameter and the height
be 1.5 times the diameter.
