Modern World
A study published in Britain in 1988, using data compiled from 1981, determined that the average height in the modern British population was 173.8 cm. [67.78 inches or 5’ 7 ¾"] for males and 160.9 cm. [62.75 inches or 5’ 2 ¾"] for females.
For modern white Americans, the average stature for males is 69.1", or just over 5’ 9", and for women, 63.7", or about 5’ 3 ¾".
So for Modern white Americans, anything below 5'9" would be considered short, but back in 17th century-Britain 5'9" would be considered tall.
