Lion vs Tiger: Size, Strength and Key Differences

Key differences at a glance

Lions and tigers are close relatives in the genus Panthera, alongside leopards and jaguars, and they are the two largest living cats. Their skeletons are so alike that experts often tell their skulls apart mainly by the shape of the lower jaw.

Despite this close kinship, they differ in almost every aspect of daily life. The lion is the only truly social cat, built for cooperative life on open plains. The tiger is a solitary ambush hunter of dense cover, from tropical jungle to the snowy forests of the Russian Far East.

Which is bigger, a lion or a tiger?

On average, the tiger is bigger, but the answer depends on which lions and tigers are compared. Tigers vary more in size than lions: the largest mainland tigers outweigh the largest lions, while island tigers such as the Sumatran tiger are smaller than an average lion.

Male Bengal tigers in India typically weigh 200–260 kg (440–570 lb), and Siberian (Amur) tigers are similar. Male Sumatran tigers weigh only about 100–140 kg (220–310 lb). Male lions are heaviest in Southern Africa and slightly lighter in East Africa and India. For a ranked list of all the big cats, see biggest wild cats.

How to tell them apart by looks

The coat is the easy giveaway. Tigers are orange to reddish with a white belly and bold black stripes. Every tiger’s stripe pattern is unique, like a fingerprint, and the stripes break up its outline in tall grass and forest shade. Lions are a plain sandy or tawny color that blends with dry grass, and adults have no stripes or spots.

Only male lions grow a mane, a thick ruff of hair around the head and neck. Tigers of both sexes have long cheek ruffs, especially in cold climates, but never a true mane. Lions also have a dark tuft at the tip of the tail, which tigers lack. Tigers have white spots on the back of their black ears; lions have plain, rounded ears.

Social life: pride vs solitary

This is the deepest difference between the two cats. Lions live in prides of related lionesses, their cubs and one or more resident males, averaging around 15 animals. Lionesses often hunt together, raise their cubs in a shared nursery and defend the pride’s territory as a team.

Tigers live alone. Adult tigers hold territories marked with scent, scratches and urine, and they meet mainly to mate. A tigress raises her cubs, usually two or three, on her own for about two years, until they leave to find territories of their own.

Their calls reflect this. Lions roar often, in choruses that can be heard up to about 8 km (5 mi) away, to keep pride members in touch and warn rivals. Tigers roar less often; a tiger’s roar carries about 3 km (1.9 mi) and is used mainly to advertise presence and find mates. See Why do lions roar? for more.

Where they live and what they hunt

Lions are cats of open country: savanna, grassland, scrub and open woodland across sub-Saharan Africa, plus the dry forests of the Gir region in India. Tigers need dense cover and water. They live in tropical and subtropical forests, mangrove swamps such as the Sundarbans, tall grasslands and the temperate and boreal forests of northeastern China and the Russian Far East.

Both hunt large hoofed mammals, but in different ways. Lions often hunt in groups and take wildebeest, zebras, buffalo and antelopes. Tigers hunt alone, stalking and ambushing deer such as sambar and chital, wild boar and sometimes gaur. A tiger can eat as much as 50 kg (110 lb) in one session, while a lion’s big meal is up to about 30 kg (66 lb). Tigers are also strong, willing swimmers; lions can swim but usually avoid water.

Who would win in a fight?

This is one of the most searched animal questions, but there is no reliable answer. Wild lions and tigers almost never meet today, and accounts of fights from ancient arenas, menageries or circuses are anecdotal and say little about how wild animals behave.

On paper, the tiger has the advantage of greater average size and long experience fighting large prey alone. A male lion is used to fighting other lions, and its mane may soften some blows. In reality, any encounter would depend on the size, age and condition of the individuals. Deliberately putting the two together would be cruel and is illegal in many countries.

Can lions and tigers interbreed?

Yes, but only in captivity, because their ranges and behavior keep them apart in the wild. A liger is the offspring of a male lion and a female tiger. Ligers often grow larger than both parents, because growth-limiting genes that normally balance each other are mismatched. A tigon comes from a male tiger and a lioness and is usually similar in size to its parents or smaller.

Most male hybrids are sterile, and many have health problems. Zoos accredited by major associations do not breed them, because hybrids have no conservation value.

Conservation: both in trouble

Both cats are threatened. The lion is listed as Vulnerable, with roughly 20,000–25,000 left in the wild; read Are lions endangered? for details. The tiger is listed as Endangered, with an estimated 3,700–5,600 wild tigers in 2022, after losing more than 90% of its historic range. Ironically, far more tigers live in captivity than in the wild.
