the major axis (the biggest axis) is related to the largest denominator .... the sqrt of the denominators gives us the "semi" axis lengths.

OpenStudy (amistre64):
since 100 is bigger than 16, sqrt(100) = 10 is smaller than the overall length; so you want an option that is bigger than 10 (twice as big to be exact)
