The typical height of Greek men at that time was around 5 feet, which Alexander the Great was. Alexander and his companions called some of the taller persons they met in their travels “giants” because he was of average height.

The Indian monarch Porus was 7 feet tall when Alexander first met him. According to Alexander’s biographer, the tall man would have looked equally at home on an elephant as a Greek man would have on a horse. Later, Alexander saw Celts who were shorter than Porus, standing 6 to 6 foot 6 inches on average. The Greeks, who stood five feet tall, believed these men to be tall enough to scratch the sky with their backs.
