There are 6 people who are bigger than O'Neal

Retired basketball player Yao Ming, standing at 2.26 meters tall, appears to overshadow Shaquille O'Neal, who is 10 centimeters shorter. 

Hollywood actor and special effects performer Calvin Lane, at 2.21 meters, also made O'Neal seem small in comparison.

Former NBA player Sim Bhullar, at 2.26 meters and 163 kilograms, earned the nickname "Indian Yao Ming" and could have been a strong defender against O'Neal. O'Neal's physique was also no match for WWE wrestler Big Show, as seen in their interaction. 

Wilt Chamberlain, an ancient beast of the NBA at 2.16 meters, remained imposing even in his older age. 

Lastly, Sultan Kösen, the world's tallest recorded person at 2.72 meters, made O'Neal look like a dwarf in a photo together. O'Neal's 2.16-meter height seemed less terrifying compared to others.
