Hello how may I help you? Hi. I'm in an argument with my husband and I was wondering if you could settle it. Who is the world's tallest man? Sure. The world's tallest man ever was Sultan Ksen. And how tall was he? 8 feet and 2.8 inches tall. Nice. My husband is only 8'1"! You just won me $20, bot. I am happy to help. Is there anything else I can assist with today? Sure, just out of curiosity, how tall was the shortest person ever? Chandra Bahadur Dangi at 21.5 inches tall Wow, that's short. Thanks! You're welcome
