A Viking's height could be anywhere between 66 inches 1.67 meters and 69 inches 1.75 meters. The tall ones are said to be Vikings of higher stature since they are likely to have better nutrition and eat better diets compared to the common Viking warriors. The notion that Vikings were tall people may also be because people in some parts of Europe are relatively short. This may be the reason why they might consider Vikings as people with increased height. But compared Viking's height to today's people, they are considered as people with average height.
Stulp, who is Dutch, studies why his fellow citizens are so tall. Today, the Dutch are on average the tallest people on the planet. Just 150 years ago, they were relatively short. In 1860, the average Dutch soldier in the Netherlands was 5-foot-5. American men were 2.7 inches taller. Since 1860, average heights have increased in many parts of the world, but no people have shot up like the Dutch. The average Dutchman now stands more than 6 feet tall. And while the growth spurt in the United States has stopped in recent years, the Dutch continue to get taller.
