Slim was only ever 6'3" in his big cowboy boots. In the 1955 movie "Santa Fe Passage", he's the same height as legit 6'2" John Payne, with both of them wearing very flat footwear throughout the film. In 1965's "In Harm's Way", Slim is an inch shorter than legit 6'3" co-star Tom Tryon. This explains why Slim is quoted on Dan Blocker's page as having to wear lifts when appearing with legit 6'3" Dan on "Bonanza".

Slim was a real life cowboy before Hollywood came calling. He was a tall, burly guy. 6'2" at the bare minimum for him, but I can also buy 6'3" for him. I'll have to keep an eye for him the next time I watch a John Wayne film and compare him to The Duke and some of the other tall, old-school classics. Despite his Western background, I like Slim best as the dopey trucking depot manager Duane in the 1975 trucker flick, WHITE LINE FEVER.

I thought he looked a good inch shorter than 6`3.5 Harvey Korman in Blazing Saddles
