Basic size facts

  • Height: 6'5" (about 1.96 m).

  • Position: Offensive tackle for the San Francisco 49ers, where that combination of height and mass is typical for an elite left tackle.

Combine and measurables

  • Pre-draft measurements listed him at just under 6'5" (6 ft 4⅝ in) and about 315 lb at the NFL Combine, showing he has been a very large lineman since entering the league.
  • He also has long arms (around 34¼ inches) and large hands (around 9¾ inches), which help him control pass rushers despite already having a huge frame.

“How big” in NFL context

  • Among offensive tackles, a 6'5", ~320 lb build puts him exactly in the prototype range for a modern elite left tackle, but his movement skills at that size are what make him stand out.
  • Fans and forum posts often describe him as a “massive human being” because he combines that bulk with rare agility and explosiveness for someone his size.
