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.
From the 10th century through to the 19th, the. average height of adult men was 5ft 7in or 170cm. - just 2in below today's average. Women were an average of 5ft 2in or 158cm - just over an inch shorter than today. All the bones in the study came from the medieval St Peter's Church in Barton upon Humber, North East Lincolnshire.
