It does not appear that Ladd Drummond’s height has been made public. Based on photographs of him standing next to his wife, whose height is known, he is likely between 5′ 11″ and 6′ 1″ tall.
Ree Drummond, the host of “The Pioneer Woman” on The Food Network, is married to Ladd Drummond. The Internet Movie Database lists Ree’s height at 5 feet, 9 inches. Ladd is noticeably taller than his wife, although by no more than a couple inches. In images with his wife, he is frequently depicted wearing a cowboy hat, making it difficult to perceive the height differential, although the difference is apparent.
