Just take a look at the average Polish male and Average Chinese man or an Indian man and one with African roots. In fact, when it comes to height ‘Our World in Data’ said recent data showed 697 genetic variants that influence the height of an individual.

Apart from genetic structures which are partly hereditary, the height of an individual is impacted by differences in living standards. Environmental settings, health, and nutrition play a key role in determining the same.

On the tangent of height, countries have adult males with similar heights as part of the bulk of the population, that gives the country its average. This changes at different ages of the individual. To shed a little light on averages across the globe here is the average height of adult men in 9 countries.

It is at this time the growth hormone is most active and helps them grow. Caffeine, stimulants, steroids, and stress can directly impact the height of the male.

  • USA 148 cm and 166 cm
  • UK- 145 cm and 163 cm
  • Canada-154 cm and 170 cm
  • Australia- 147 cm and 173 cm

As the height at the age of 12 does not vary significantly. Further, amongst adults, it is clear that there is not a tremendous amount of change after the age of 19. Changes at this point are usually attributed to individual genetics.

History of the height of men

The average kept bouncing back and forth but settled at 170cms or 5.57 feet globally. Over the past 100 years, the average height in every country of the world has increased.
