How Tall Was Pernell Roberts? the Surprising Truth Behind the Bonanza Star's Stature
By Maya Lin-Takahashi
Television framing is entirely relational. Place an average-height actor next to someone five-foot-seven, and he looks like a giant. Place a six-foot actor next to Dan Blocker, and he shrinks instantly.
Blocker, cast as Eric "Hoss" Cartwright, was an absolute mountain of a man. Standing 6 feet 4 inches and tipping the scales at over 300 pounds, Blocker cast a literal and figurative shadow over every scene. Next came Canadian radio veteran Lorne Greene, who played family patriarch Ben Cartwright. Greene stood a solid 6 feet 1.5 inches, possessing a barrel-chested build and thick silver hair that added vertical presence.
Then there was Michael Landon, cast as younger brother Little Joe. Landon measured approximately 5 feet 9 inches naturally. To avoid looking diminutive next to Blocker and Greene, Landon famously wore customized cowboy boots featuring internal lifts and elevated heels, effectively pushing his working stature to nearly 5 feet 11 inches. Roberts, standing dead-center between these deliberate height adjustments and Blocker's natural mass, routinely appeared to be the shortest Cartwright on screen, despite being taller than Landon and well above the average American male height of the era (5 feet 8 inches in 1960).
