OUR ANCESTORS were as tall as we are, contrary to popular belief. Over the past five millennia the average height of men in Britain has remained stable at about 170cm (5ft 7in), and that of women at 160cm (5ft 3in). We may be surprised at how small the armour worn by the Black Prince or King Henry V was, but such giants on the battlefield were not physically large and were towered over by contemporaries of all classes.

“The enduring myth that people in the past were much shorter than we are today contains a small element of truth,” writes Sebastian Payne, chief scientist at English Heritage, in British Archaeology. “There have been small changes, and average height has increased by an inch or so over the past 50 years,” he says, attributing the increase to better health and nutrition.

The myth seems to stem from such things as low doorways on some medieval houses, and the small suits of clothes and armour in museums. But Dr Payne says that there are plenty of tall doors, and we simply don’t register “normally” sized outfits. “Recruits in 18th and 19th-century military records were considerably below today’s average heights,” he says, but adds: “Recruits are often from poorer families whose average height is less, and were often not fully grown.”

In the abandoned medieval village of Wharram Percy in Yorkshire, the churchyard has yielded hundreds of skeletons for analysis. There “ten-year-olds were around 8in shorter than children today: by the time they were fully grown they were nearly as tall as modern adults”.

A study by Charlotte Roberts and Margaret Cox, drawing together evidence of stature from skeletons across the country, shows that adult heights in both sexes have remained constant since the Neolithic era.
