no.... the MTB world adopted a "standard" of 63mm or so... Some tiny road bike frames need a shorter taper to fit.. others can get away with a much longer taper, or one that begins farther up the steerer tube...
remember... the larger the tube's diameter, the stiffer it acts, while also being able to be thinner, to a point.
