Question: is 5'8 short for a male?
Answer: You are shorter than the average adult male in many countries but not by much. Standard deviation of height in men is about 7cm or 2.5″ and 2/3rd of the popualtion will be within 1sd of the mean. That means over 1/6th of the population will be your height or shorter. That's a lot of people to label “short”.
