Size matters on the Matterhorn ... especially when you're 6'11" like NBA star Anthony Davis.
The New Orleans Pelicans big man hit up Disneyland on Sunday and decided he wanted a ride on one of the oldest coasters in the park.
The problem ... leg room.
You can see in the pics, Davis went full knees-to-chest to fit in the bobsled -- and apparently, it worked. We're told he had a blast at the park.
Fun Fact: There's a secret basketball court tucked away inside the mountain. No word on if AD got to hoop in between rides.
