2. South Dakota – 5’11.3″
Just edging out its northern neighbor, South Dakota comes in second with an average height of 5 feet 11.3 inches. Its population shares similar ancestry—mainly German, Norwegian, and other Northern European backgrounds—making tall stature a common trait. Residents here also lead healthy, active lives from a young age. Whether it’s hiking in the Black Hills or playing football under Friday night lights, South Dakota boys have the foundation they need to grow tall. It’s a quiet, rural state, but when it comes to height, South Dakota speaks volumes.
