T Rex, while in an upright position, could reach a height exceeding 17 feet (5.1 meters); however, when gauged from the ground up to its hips, Tyrannosaurus Rex ranged between 12 and 13 feet (3.6 to 3.9 meters). To provide a point of reference, the tallest giraffe on record measured 5.7 meters (18 ft 8 in).
There is a scientific principle behind them, even with these approximations of how tall T Rex were. However, due to their inherent nature, most of the statistics you come across regarding dinosaurs are the most accurate approximations to clarify. There are guidelines that are applicable when assessing the height of dinosaurs.
In addition to being the tallest of all dinosaurs, as well as other dinosaurs and present-day animals, we will explore the height of a T Rex and assist you in comprehending the methods employed by paleontologists to measure dinosaurs.
You can see more information in the table below, as well as in the linked article above and below. Both huge dinosaurs were about 40 feet long and had tall hips at about 13 feet. There is a competition between two fossil discoveries, one called Sue and the other called Scotty. You can read more about the largest known fossil, Rex T, in the article here and learn about how big it was in our time.
Although it is possible that Scotty thought it would prove to be bigger, it has actually been proven that Sue is over 90% complete, while Scotty is only around 60-65% complete. When it comes to size and height, Sue currently has the edge, making it more provable as the complete fossil.
Rex, the Scotty, was considered to be taller and heavier compared to Sue, with a height of at least 17 feet and a raised head. Additionally, Sue was thought to be at least 13 feet tall.

Dinosaurs as Tall As a T- Rex.
In the section next to this one, we will take a quick look at Rex T, which were dinosaurs and both carnivores and herbivores. However, there were plenty of large dinosaurs that were just as tall as T-rex, but there is no doubting that Rex T was a particularly tall dinosaur, especially for a carnivore and theropod.
If you understand our point, there exist some quite renowned dinosaurs that could have directly confronted a T Rex (although not engaged in direct combat with it). Therefore, if we consider the height of the T-Rex to be around 13 feet, measured up to the hips since it was probably more horizontally positioned rather than vertical, at least for the majority of its existence.
Herbivore Dinosaurs As Tall As A T Rex
We have a few instances below of plant-eating dinosaurs as tall as a Tyrannosaurus Rex.
Head its crest was long and it had 5 feet. Parasaurolophus was a dinosaur with a crest on its head and long feet. Although it was about 9 feet tall at the hips, it would have been much taller, about 15 feet, when standing upright.
If Rex T were to meet them, they could be on a level playing field. However, the ground was much lower, so their heads would be lowered. Measuring about 3 feet tall, their heads were much closer to the ground. However, it could reach heights of 13 to 14 feet, including its hips. The Stegosaurus certainly had huge plates running along its back, which definitely aided in its height measurements.
If we were to measure from the hips, we would find that Rex T, standing at about 15 feet tall, is approximately the average size of a Diplodocus. However, these long-necked dinosaurs were universally taller than Rex T, so it is not surprising to see him on this list of dinosaurs.
Carnivore Dinosaurs as Tall as T Rex
The Allosaurus, although much heavier than the Predator, would not be a match for it. However, it was believed to have a much more upright posture than other dinosaurs and was estimated to stand up to 16.5 feet tall. If they were alive at the same time, it could still look into the eyes of the Allosaurus, but it has a length that is about 25% less than Rex T.
It is fortunate for both of these massive predators that they may have been a little shorter at the hips, even compared to a T-Rex standing at a height of 13 feet. It is said that in terms of height, including all aspects, it may be comparable to the largest predator that ever walked the Earth, although it is said that in the movie Jurassic World Dominion, it may or may not be the largest predator that ever walked the Earth: Giganotosaurus. It is fortunate for both of these massive predators that they lived on different continents and apart from each other for 50 million years.
T Rex, which is believed to be one of the largest predators ever, stood at a height of about 4 meters at the hips. Another carnivorous dinosaur that is comparable in size and height to T Rex is Carcharodontosaurus.
What Dinosaurs were Taller than a T Rex?
The Spinosaurus, believed to be the longest and tallest, was the solitary meat-eating dinosaur that could potentially surpass a T Rex in height. Nonetheless, the majority of dinosaurs were plant-eaters. Numerous dinosaurs exceeded the height of a T Rex.
With a height surpassing that of a T Rex, the sail along its back extends to 21 feet tall (6.5 meters), making it equally if not slightly taller than a T Rex. From the head to the hips, it was estimated to reach a height of 16.5 feet (5 meters).
The enormous carnivore, slightly taller than the T Rex, and Face to Face establishes its height compared to a T Rex, which stood at 4-5 meters tall, is believed to be the herbivorous, long-clawed plant-eating dinosaur known as Therizinosaurus, a large theropod.
The Sauropisian is believed to be the tallest dinosaur, if not the tallest, although its height often varies as new data is discovered, presently. The exceedingly colossal Sauropods held that position but it was not necessarily the tallest dinosaur. Tyrannosaurus Rex might have had a significant height.
Rex T is about 10 times taller than regular people and is over 4 times as tall as that (approximately 60 feet or 18 meters). This dinosaur could reach heights that are incredibly high due to its exceptionally long neck, which was even longer than the front legs of most other long-necked dinosaurs in the brachiosaur family.
How Tall Were T Rex Babies.
To this day, no Preserved Eggs or Baby T Rexes have been discovered. Shortly after emerging from their eggs, T Rex infants would have measured approximately 3 feet in length and 1 foot in height (30cm). They experienced rapid growth, and by the age of 11, they would have attained a size substantial enough to devour smaller dinosaurs. The T Rex eggs would have measured approximately 17 inches long, which is believed to be comparable to the size of a petite canine.
Depending on the T Rex’s family of insects, it is possible that they had a diet consisting of kills from their parents as well as other kills that were scavenged from lizards and insects. However, they would only have tall feet measuring 1-2 feet.
When they were considered adults, dinosaurs that weighed around 16,000 pounds would have grown from about 5 feet high in their early years to around 9-8 feet high in their teenage years, and eventually reached a height of about 8-9 feet when they were around 12 years old.
How Tall Is a Fully Grown T. Rex?
We will now take a look at how Rex, who is currently thought to be a baby T-Rex, looked like at birth. Rex was about 30 cm tall (approximately 1 foot) and 1 meter (about 3 feet) long, although his height was similar to that of a small dog.
Tyrannosaurs, which were discovered to be teenagers at the ages of 15 and 13, weighed about 1000 kg (2200 lbs) and had a length of approximately 6 to 4.5 meters and a height of 8-6 feet. In their first few years, these two tyrannosaurs quickly grew to be heavier and taller, managing to become more dangerous as they entered the late Cretaceous period.
During that period, their mass would have soared by a colossal 16,000 pounds (7,000 kilograms). Growing up to 40 feet long and 13 feet tall, these adolescent T Rexes were anticipated to more than double in size. By the time it reached approximately 20 years of age, a T Rex would be regarded as fully grown.
Recently, these dinosaurs have been classified as separate species of carnivorous dinosaurs during their teenage and infant years, such as Nanotyrannus, which were thought to be smaller and shorter in length for a long time.
We have a Table below to help put how tall is a T Rex at different stages of its life into perspective.
Conclusion
The stature and pelvis are far more stable than the height of the head or neck as it provides a more precise indication of height. With its head held high, this stature could reach a staggering 17 feet. An adult Tyrannosaurus Rex would typically stand at an average height of 12 to 13 feet when measured from the ground up to its pelvis. The measurements are specifically taken up to the pelvis.
During its adolescent stage, Tyrannosaurus rex reached a height of 8-9 feet, maturing and thriving for more than two decades before attaining its full adult size. As mentioned earlier, when it hatched, it was estimated to be approximately 3 feet in length and around 1 foot (30 cm) in height.
During the challenging adolescent phase, similar to humans, a T-Rex undergoes a growth spurt. At this time, a T-Rex can increase its height by 5 feet and its weight by a staggering 14,000 pounds!
I would rather encounter a T Rex or a brachiosaurus, but it might not be the tallest of the dinosaurs!
How Tall Was T Rex Compared to Modern Animals.
Today on Earth, we currently have an abundance of sizable predators and plant-eating creatures. In order to determine their height in comparison to a T-Rex, we conducted some investigation. We have provided various comparisons of the biggest modern-day animals to ascertain whether they could match the T-Rex’s height. Additionally, we have included information about their length and weight to allow you to observe the disparity between present-day predators and those from the era of dinosaurs.
As you can observe in every aspect, the T Re was taller, heavier, and longer than all current large mammals.
Why do they measure dinosaur height to the hips?
Below, we emphasize the rationales for undertaking this task, which holds particularly true for theropods. However, it is important to note that not all dinosaur height measurements are taken from the ground to the highest point of the hips. The majority of them are, though.
How to measure Dinosaur Height
Paleontologists have a few reasonably accurate ways to measure the height of extinct dinosaurs, including the towering Tyrannosaurus rex; however, it can be a tricky business due to the limited availability of fossils.
We have a vast selection of articles or a huge collection of answers to common and less common questions about the Tyrannosaurus Rex on the site below the table.
Was being tall useful for T Rex for Hunting?
Being of greater height, the T Rex found it easier to detect prey or potential dangers. Additionally, this elevated perspective provided a better vantage point for observing its surroundings. In confrontations over food or mates, possessing height also served as an indication of dominance when interacting with other T Rex individuals. Rather than a disadvantage, being tall was predominantly advantageous in the prehistoric realm where the principle of “Might usually made Right” held true.
If animals in the modern animal kingdom, such as bears, do not use their height for actual hunting, they would have a distinct advantage in being able to raise their heads to smell the air and raise their noses and eyes to both smell the air and keep the smell of the air away from their noses and eyes.
