How tall were humans 1000 years ago?

Answer 1

European males were estimated to have measured about 1,83m (6 ft) some 40.000 years ago. About 10.000 years ago, climate change and the adoption of agriculture caused a reduction to about 1,62m (5ft4). 600 years ago, European males were about 1.65m in length, as the Little Ice Age hitting Europe and general poverty coincided. Since then, a steadily improving diet has allowed the average European male to grow to an average of 1.75m (5ft9).

Note that these figures are for European males only, and do not apply to women or humans from other descent.
