Thats comical. Honestly it is. Elves look more buff and larger than humans. Which, based on the PHB I'm looking at, is flat wrong.
Please Larian. Fix this stuff...
The question is why did they get it so wrong in the first place? It's like the source material wasn't even consulted.
It couldnt have been. It literally could not be more clear.
Straight from the Players Handbook.
With their unearthly grace and fine features, elves appear hauntingly beautiful to humans and members of many other races. They are slightly shorter than humans on average, ranging from well under 5 feet tall to just over 6 feet. They are more slender than humans, weighing only 100 to 145 pounds.
