If by "optimium" you mean to reach the point where the resistive portion
of the feedpoint impedance is 50 ohms (and not with respect to radiation
pattern), then it depends on the length of the vertical section. If
the vertical section is short, the feedpoint impedance will be low and
the horizontal section will have to be longer to make up the difference.
