A lion is strong enough to kill antelope and even young elephants, but few lion strength numbers are measured. In a 2023 study, a captive lioness bit a sensor with 1,594 newtons, about 163 kg (358 lb) of force. Males weigh 150 to 260 kg (330 to 570 lb), says San Diego Zoo.
How strong is a lion’s bite?
The lioness in that 2023 study was named Savannah. Scientists fitted a bite plate with a sensor to a food box. Each time she bit harder than a set level, she got a reward, and the level went up. Her best bite, with her front teeth, was 1,594 newtons. A newton is a unit of force, and about 10 newtons equals the push of 1 kg.
That is one lioness biting with her front teeth. A lion’s back teeth, closer to the jaw hinge, would bite harder. So her number is a floor, not a ceiling. It is still the only direct lion bite measurement we could find.
An older method estimates bite force from skulls. In 2005, Wroe and colleagues measured dry skulls and treated the jaw as a lever. Their big lion skull gave a canine bite of about 1,768 newtons.
| Animal | Bite force | About equal to | How it was found | Source |
|---|---|---|---|---|
| Lioness (front teeth) | 1,594 N | 163 kg (358 lb) | Measured, one captive lioness | van der Meijden et al. 2023 |
| Lion (canines) | 1,768 N | 180 kg (397 lb) | Modelled from a skull | Wroe et al. 2005 |
| Tiger (canines) | 1,525 N | 155 kg (343 lb) | Modelled from a skull | Wroe et al. 2005 |
| Jaguar (canines) | 1,014 N | 103 kg (228 lb) | Modelled from a skull | Wroe et al. 2005 |
| Spotted hyena (canines) | 773 N | 79 kg (174 lb) | Modelled from a skull | Wroe et al. 2005 |
| Spectacled bear | 2,197 N | 224 kg (494 lb) | Measured, captive bears | van der Meijden et al. 2023 |
What about the “650 PSI” or “1,000 PSI” you may see online? PSI is pressure, not force, and we found no study behind either figure. The old version of this page used both numbers at once, which tells you how shaky they were.
How do lions use their strength to hunt?
Lions rarely win by strength alone. Lionesses do most of the hunting, and several may creep toward prey from different sides to within 30 m (100 ft) before they charge, says the Smithsonian’s National Zoo. Then they use strong forelegs, teeth and jaws to pull the animal down.
Teamwork lets lions take prey much bigger than one lion. San Diego Zoo lists antelope, zebras and other hoofed animals, plus baby elephants, rhinos and even crocodiles. After a kill, a male can eat about a quarter of his body weight, up to about 64 kg (140 lb), in one meal.
How strong is a lion’s paw swipe?
Nobody knows. You will find claims that a lion’s swipe hits with 400 lb (180 kg) of force, or that a lion can lift 2,300 lb (1,040 kg). We found no study that measured either one. A lion weighs at most about 260 kg, so lifting four times its own weight would be a strange feat for a cat.
What we do know is that a lion’s front legs are thick and heavy, built to grab and hold struggling prey. The claws pull back into sheaths when not in use, so they stay sharp. A lion that swipes at you is dangerous, whatever the exact number.
How loud is a lion’s roar?
A lion’s roar is one of its most measured powers. Close up, it reaches about 114 decibels at 1 m (3 ft), according to a 2011 study of lion and tiger voices. Lions and tigers can roar so deeply because their vocal folds are flat and square, not thin and pointed.
How far does a roar carry? The Smithsonian says up to 8 km (5 miles), while San Diego Zoo says 4.8 km (3 miles). The difference probably comes from wind, ground and how quiet the night is. The old claim that one roar will make you deaf is not backed by any study we found.
Is a male lion stronger than a lioness?
Male lions are bigger. Males weigh 150 to 260 kg (330 to 570 lb) and females 122 to 180 kg (270 to 400 lb), San Diego Zoo says. Males are also longer, up to 2.5 m (8.3 ft) without the tail. A heavier body usually means more muscle, so a male can probably pull and hold harder.
But females are the main hunters. They are lighter and faster, and a lioness can sprint at up to 53 km/h (33 mph). Males use their bulk to guard the pride and fight rival males. So each sex is strong in the way its job needs.
Is a lion stronger than a tiger?
On average a tiger is a bit heavier, and heavier cats tend to be stronger. In the 2005 skull model, the lion skull bit harder than the tiger skull, but that lion was also much bigger. Adjusted for size, the tiger scored higher. Our page on tiger vs lion: who would win lays out the whole comparison, and how strong a tiger is gives the tiger side.
How strong is a lion compared to a human?
There is no fair test, so be wary of claims like “a lion is 7.5 times stronger than a person”. What we can compare is size. A big male lion weighs about as much as three or four adults. A lion’s bite is far stronger than yours, and its claws and teeth are made for gripping prey.
That is why lions are dangerous to people. In parks with lions, follow the rangers’ rules, such as staying inside your vehicle. Lions are listed as Vulnerable on the IUCN Red List (2023 assessment), and people kill far more lions than lions kill people, as our page on what eats lions explains.
Quick facts: lion strength
- Measured bite: 1,594 N from one lioness’s front teeth.

- Male weight: 150 to 260 kg (330 to 570 lb).
- Roar: about 114 decibels at 1 m.
- Paw swipe and lifting strength: never measured.
Frequently asked questions
Can a lion break a bone with its bite?
Lions do eat bones of smaller prey, and their back teeth act like scissors for slicing meat and gristle. Their bite is modelled at about 1,768 newtons at the canines. Spotted hyenas are the true bone-crackers of the savanna, with teeth and jaws shaped for that job.
How fast can a lion run?
A lioness can sprint at up to 53 km/h (33 mph), says San Diego Zoo Wildlife Alliance. Lions can only keep this up for a short dash, so they creep close to prey before they charge. The old claim of 80 km/h is not supported.
How many lions are left?
About 22,000 to 25,000 lions live in Africa and just under 700 in India, according to San Diego Zoo Wildlife Alliance. The IUCN Red List lists the lion as Vulnerable in its 2023 assessment. Habitat loss and conflict with farmers are the main threats.
Why do lions hunt in groups?
Hunting as a team lets lions tackle big, dangerous prey that one lion might not bring down alone. Several lionesses spread out and creep closer from different sides before they charge, says the Smithsonian's National Zoo. Group hunting also helps them defend a kill from hyenas.

This info is somewhat inaccurate. Lion’s bite force rivals tigers and hyenas at around 1,000 psi and lions average the same size and strength of tigers.
Lions can’t defeat all kinds of bears. Especially polar bears which are the largest and strongest land predators.
I bet they can
These ‘facts’ arent so accurate. For starters, a paw strike force of 400 lbs is weak af. Amateur boxers can hit harder than that. It would be more like 2,500 lbs of force. Also, Tigers do not have a stronger bite force. Thats a myth. The 1050 lbs bite listed for the Tiger is an estimate, while only the bite of a subadult male Lion was measured at 691 lbs (not 650 psi)
