Olympic gymnast Simone Biles, who is just 4-foot-8, recently posted a photo of her standing back-to-back with U.S. men's volleyball player David Lee, who is 6-foot-8.
Olympians come in all shapes and sizes, but the height difference in this photo is incredible.
Now Lee is one tall guy, but according to FOX Sports, he isn't the tallest on the U.S. Olympic team.
Basketball players DeMarcus Cousins and DeAndre Jordan are both 6-foot-11.
But as Biles pointed out, size difference in Olympians doesn't matter -- depending on which sport they are competing in of course.
