Size contrast aesthetics

I've been thinking about aesthetic size contrast between the penis and a girls body, so her height. With a 6.2 inch penis, I would say it looks good and sexy with girls up to 170 cm tall, or 5 ft 7. If the girls is any taller it begins to look on the short side. For example with a 5.9 ft girl I dated, visually the penis looked small under her and in her hands. So I've thought about this rule which may apply for good appearance. What do you think?

4.5 - 5 inches: 150-160 cm girls.
5.5 - 6.5...
