One of the giants was 7’9” tall (2.36 m) while the “shorter” one was a mere 7’4” tall (2.23 m) and according to various sources they were indeed twin brothers. They created quite an impression at the Durbar as they literally stood heads and shoulders above the rest. The brothers were known as the Two Kashmir Giants and were elite riflemen in the service of the Maharaja. https://rarehistoricalphotos.com/kashmir-giants/
I wonder if the professor is really small, or are the guards giants?
So ya they were pretty big.
