This sort of question is like asking "How long is a piece of string?" The whole of the aircraft design has to be considered and how the effects of the parts interact. Some high wing types have anhedral, some dihedral and some are neutral. It depends on how all the factors interact to affect the stability and if there are other considerations (outriggers for example) that must be allowed for.
Some factors that can affect things include low CG, high keel surface, sweepback, desired amount of stability (or even instability), fin area and lots of others I could probably recall if I thought longer.
