Alexander the Great stood about 5 feet tall, which was about average for a Greek man at the time. Alexander was about average height, so he and his friends called people who were taller than him “giants.”
When Alexander met the Indian king Porus, he was surprised by how tall the man was: 7 feet. Alexander’s biographer thought the tall man would look just as good on an elephant as a Greek man did on a horse.
Later, Alexander met Celts who, on average, were not as tall as Porus. They were between 6 feet and 6 feet 6 inches tall. Still, the Greeks, who were only 5 feet tall, thought these men were tall enough to reach up and scratch the sky with their backs.
