Sam is just tall!
Jared is 6'4". Jensen's height is listed at 6'1" just about everywhere, but unless it's their footwear, he always seems to me to be about 4 inches shorter than Jared, so possibly he's 6'. Jeffrey Dean Morgan is 6'2", so yeah, they make Dean look short!
no Sam is just really tall it does not mean Dean is short , i actually saw an episode 2 Jared in ER and he was sleeping in bed at the hallway and his leg was out of it so yeah he is so tall but Jensen is not short he fits
It's both. Jared Padalecki is 6'4" (and his brother in real life is taller..), and Jensen Ackles is around 6', as is Misha Collins.
However, I've always imagined it another way. Yeah, Sammy is the little brother, but he's a giant because Dean always gave him his food, therefore making Dean shorter and malnourished (hence the bowlegs we constantly make fun of).
Sam is very tall. His height is listed as being 6'4" and 1/2, probably closer to 6'5." Dean is 6'1" or 6'2." So they're both tall, it's just that Sam is taller.
He's been given many nicknames that make fun of his height, most notably "Sasquatch," "Jolly Green," "Big Bird," "Giraffe," "Winchester Jumbo Sized," "Bullwinkle," and Crowley's most favorite, "Moose."
Jensen's height is indeed over average, 1.85m, most people would have to raise their head to look at him. But unfortunately, he can never look tall standing with Jared, who is 1.94m. I guess that's how most people get the impression of Jensen being short, since they always appear on the media together, let alone the show.
