Who is bigger T. rex or King Kong?

King Kong and T. rex are two of the most iconic giant creatures in pop culture history. They have faced off numerous times on the big screen, with fans hotly debating who would win in a fight. When it comes to sheer size, which monster is truly larger? We’ll examine the official stats and dimensions of each beast to solve this size showdown once and for all.

T. rex Size and Dimensions

Tyrannosaurus rex is undoubtedly one of the largest and most fearsome predators to ever walk the Earth. Making its debut in Jurassic Park, this colossal carnivore has continued to capture the imagination of audiences worldwide. But just how big was T. rex in real life?

According to experts, an adult T. rex stood around 12-13 feet (3.6-4 meters) tall at the hip. When standing fully upright, some specimens could have reached over 20 feet (6 meters) in height. T. rex possessed a massive head that could measure over 5 feet (1.5 meters) long, showcasing dozens of sharp, bone-crushing teeth up to a foot long. Its slender S-shaped neck helped balance and support the giant skull.

In terms of length, adult T. rex individuals ranged between 35-43 feet (10.7-13 meters) from head to tail. The tail alone accounted for over half of the dinosaur’s total body length. Some of the largest or longest T. rex specimens may have exceeded 45 feet (13.7 meters) in length from snout to tail tip.

When it comes to weight, most adult T. rex tipped the scales at over 6 tons (5,700 kg), with some exceptionally big individuals weighing over 8 tons (7,300 kg). The largest individuals likely weighed around 10 tons (9,100 kg).

With their massive heads, lengthy tails, and multi-ton weights, T. rex were enormous predators. But they were lightly built for their size, with hollow bones and slender frames compared to their colossal skulls. This allowed T. rex to reach such staggering dimensions while still being able to move at impressive speeds to hunt prey.

T. rex Size Summary

  • Height: 12-13 ft (3.6-4 m) at hips, up to 20 ft (6 m) tall standing
  • Length: 35-43 ft (10.7-13 m), 45 ft (13.7 m) for largest specimens
  • Weight: 6-8 tons (5,700-7,300 kg) on average, up to 10 tons (9,100 kg) for biggest
  • Massive 5 ft (1.5 m) long skull with 3 ft (1 m) teeth
  • 55+ ft (16.7 m) long with tail

King Kong Size and Dimensions

Turning to the giant ape, King Kong has varied in size across his numerous big screen appearances over the decades. But he has always dwarfed his human co-stars, truly living up to his “Eighth Wonder of the World” billing. Just how gigantic is the legendary Kong?

In the classic original 1933 film, King Kong stood about 18-24 feet (5.5-7.3 meters) tall. Later films depicted him as taller, with sizes ranging from 30-60 feet (9-18 meters) in height. Peter Jackson’s 2005 version featured one of the largest renditions of Kong, standing around 50 feet (15 meters) tall with an upright height nearing 100 feet (30 meters).

In terms of length, King Kong has been portrayed from 60 feet (18 meters) to over 170 feet (52 meters) long from head to toe. His arms have spanned up to 60 feet (18 meters) wide when outstretched!

Estimating Kong’s weight is trickier, as only some films have provided official numbers. In the original film he weighed around 20 tons (18 metric tons). In Peter Jackson’s version, Kong weighed 25 tons (23 metric tons). Based on his enormous size across films, guesses for Kong’s weight range from 10 tons up to 75 tons!

King Kong possesses a barrel-chested, muscular build compared to the thinner T. rex. And his primate anatomy allows for more agile climbing and arm movement. But it also restricts how tall Kong can stand fully upright. While gigantic, King Kong has varied more in size than the real-world constrained T. rex.

King Kong Size Summary

  • Height: 18-24 ft (5.5-7.3 m) in original, up to 100 ft (30 m) in remakes
  • Length: 60-170 ft (18-52 m)
  • Weight: 10-75 tons
  • Arms 60 ft (18 m) wide when outstretched
  • Barrel-chested, muscular build compared to T. rex

T. rex vs. King Kong: Who is Bigger?

Based on the average maximum sizes, King Kong is taller but T. rex is longer from head to tail. Kong weighs anywhere from 10-75 tons depending on the film, compared to T. rex averaging 6-8 tons and maxing out around 10. So Kong claims the advantage in sheer mass and strength. But the smart money for size depends on how you measure it.

Looking at their most iconic movie matchups helps shed some light:

1962’s King Kong vs. Godzilla

This Japanese film featured Kong measuring 148 feet (45 m) tall. T. rex did not appear, but Godzilla was 164 feet (50 m) tall. So Kong was quite a bit shorter than Godzilla.

1967’s King Kong Escapes

In this Toho Studios production, Kong stood 60 meters (197 feet) tall and weighed 30,000 tons. The T. rex equivalent, Mechani-Kong, stood only 50 meters (164 feet) and weighed 20,000 tons. Kong had the edge in both height and weight.

2020’s Godzilla vs. Kong

The most recent MonsterVerse entry depicted Kong as 104 feet (31.7 m) tall with a weight around 158.8 tons. Godzilla stood 393 feet (119.8 m) tall and weighed a massive 99,634 tons. So Kong was dwarfed by Godzilla’s sheer mass. No T. rex appeared.

Based on these classic movie matchups, King Kong ranges from equal to significantly shorter and lighter than both T. rex and Godzilla. While some films have boosted Kong’s stats, he consistently measures smaller than other titans like Godzilla. So in a battle of pure height and mass, T. rex likely holds the overall size advantage.

T. rex vs. King Kong Size Comparison

Dinosaur Average Height Average Length Average Weight
T. rex 12-20 ft (3.6-6 m) 35-43 ft (10.7-13 m) 6-8 tons (5,700-7,300 kg)
King Kong 25-60 ft (7.6-18 m) 60-170 ft (18-52 m) 10-75 tons

Factoring Movement and Abilities

Looking solely at size measurements misses key advantages and abilities each creature possesses. T. rex had puny arms, but made up for it with a massive crushing bite. Kong lacks raw size but is highly intelligent and more agile due to his ape anatomy. He can grab, punch and use objects as tools and weapons.

King Kong’s muscular arms provide tremendous strength to throw massive rocks or even tear apart T. rex jaws. His grip gives him a key advantage T. rex lacks in close quarters combat. And Kong has enough speed and dexterity when climbing to potentially exploit the T. rex’s stiff, less mobile body.

But T. rex had extremely powerful legs that allowed it to run 25 mph (40 km/h), granting scary speed for its bulk. It could lunge and close short distances rapidly to knock even Kong off balance. And T. rex jaws generated 6 tons (5,443 kg) of crushing bite force, enough to easily break Kong’s bones.

At close range, Kong has the edge. But if T. rex keeps some distance, it can use its speed and bite to finally wear Kong down after an epic battle. There would surely be no clear winner between these iconic titans!


While King Kong measures taller and heavier in most movie appearances, when comparing average maximum sizes across their film histories, T. rex generally comes out on top in terms of raw length and mass. But Kong possesses greater intelligence to strategize and special primate abilities like grabbing and swinging to compensate for his smaller stature.

Ultimately, there is no definitive answer to this epic size showdown. Kong may stand taller, while Rex is longer from head to tail. The ape racks up more weight, but the dinosaur’s pure bite force is a trump card. Average height and length favor T. rex just slightly. But Kong makes up for being the “underdog” with other physical and mental gifts to even the playing field against his enormous saurian rival.

Their sheer presence and symbolic stature as apex titans of their respective dominions remain equally matched. When it comes to cinematic icons that have stood the test of time, both the Eighth Wonder of the World and the Tyrant Lizard King are truly kings in the pantheon of giant monster greatness.
