Re: What is the average height of man?

Before I answer this question, there are two things to point out. First, I 
am asuming you are asking for the average height of a person in the United 
States, though that is not clear from your question. Secondly, questions 
such as these can easily be answered by means of a net search engine such 
as google.com, ask.com or dogpile.com by simply imputing the query "average 
height of man".       

                              
                The average height for an early 17th-century English man
                was approximately 176 cm (5’ 6"). For 17th-century English
                women, it was about 181 cm (5’ 8"). While average heights in
                England remained virtually unchanged in the 17th and
                18th centuries, American colonists grew taller. Averages
                for modern Americans are just over 183 cm (5’ 9") for men, and
                about 168 cm (5’ 3") for women. The main reasons for this
                difference are improved nutrition, notably increased
                consumption of meat and milk, and antibiotics.
