A male Siberian tiger typically weighs around 380–450 pounds (180–205 kg), measures about 10–11 feet (3–3.3 meters) long including the tail, and stands roughly 39–42 inches (100–110 cm) at the shoulder. Large males can exceed 450 pounds, but verified wild records rarely surpass 220 kg (485 lbs).
Also called the Amur tiger, this subspecies lives in the frozen forests of Russia’s Far East. Its size comes from cold weather, big prey, and thousands of years of adaptation.
Siberian Tiger Size at a Glance
Average Siberian Tiger Weight (Male vs. Female)
Male Siberian tigers average around 390 to 400 pounds in the wild. Females average closer to 260 pounds. This gap exists because males need extra muscle mass to fight rivals and take down large prey like elk and wild boar.
Captured and radio-collared tigers studied by Russian and American researchers between 1992 and 2010 recorded male weights ranging from 125 to 212 kg (275 to 467 pounds), with most healthy adults sitting closer to the middle of that range.
Average Siberian Tiger Length (Nose to Tail)
Total body length for males runs 185 to 220 cm for the body alone, plus a tail of 90 to 110 cm. Add it together and a big male can reach 11 feet nose to tail tip. Females measure roughly 8 to 9 feet total.
Siberian Tiger Height and Shoulder Measurements
At the shoulder, an adult male stands about 39 to 42 inches (100 to 110 cm) tall. That’s roughly chest-height on an average adult human — which is why a standing tiger looks so much bigger than people expect.

Siberian Tiger Size Comparison
Siberian Tiger Size vs. Lion
The male Siberian tiger weighs around 380–450 lbs (180–205 kg) and measures 10–11 feet long, including its tail.
A male African lion weighs about 330–420 lbs (150–190 kg) and reaches 8.2–10.5 feet in total length.
However, the African lion is taller at the shoulder, standing around 47–50 inches, compared with the tiger’s 39–42 inches.
The Siberian tiger also has a stronger bite force, at roughly 950 PSI, compared with about 650 PSI for the African lion.
Bengal Tiger vs. Siberian Tiger Size
The male Siberian tiger typically weighs 380–450 lbs (180–205 kg) and measures 10–11 feet long, while the male Bengal tiger can weigh 397–570 lbs (180–258 kg) and reach 9–10 feet in length.
Their skull lengths are remarkably similar, with Siberian tigers measuring about 330–380 mm and Bengal tigers around 332–376 mm.
The verified heaviest wild Siberian tiger weighed 467 lbs (212 kg), while some Chitwan/Nepal field data reports Bengal tigers exceeding 500 lbs (227 kg).
Overall, Bengal tigers can be heavier, while Siberian tigers are generally longer.
Siberian Tiger Size Comparison With Other Tiger Subspecies
| Subspecies | Male Weight Range |
|---|---|
| Siberian (Amur) Tiger | 380–450 lbs (180–205 kg) |
| Bengal Tiger | 397–570 lbs (180–258 kg) |
| Indochinese Tiger | 330–430 lbs (150–195 kg) |
| South China Tiger | 287–386 lbs (130–175 kg) |
| Sumatran Tiger | 220–310 lbs (100–140 kg) |
| Malayan Tiger | 220–285 lbs (100–129 kg) |
Siberian Tiger Size vs. Human
A male Siberian tiger weighs around 380–450 lbs (180–205 kg), nearly twice the weight of the average US adult man at about 198 lbs (90 kg).
The tiger measures 10–11 feet from nose to tail, while an average adult man stands about 5.75 feet tall.
At the shoulder, the Siberian tiger reaches 39–42 inches, roughly around hip level on an average man.
The tiger also has a much stronger bite force of about 950 PSI, compared with approximately 150–200 PSI for a human.

What Determines Siberian Tiger Size
Cold Climate and Bergmann’s Rule
Bergmann’s rule is a biology principle: animals living in colder climates tend to have bigger bodies. A larger body holds heat better because it has less surface area compared to its volume. This is a major reason the Siberian tiger outgrew its tropical cousins.
Thick fur and a fat layer up to 4 cm (1.5 inches) thick add extra insulation, which also adds visible bulk in winter coat.
Diet, Prey Size, and Body Mass
Wild boar, red deer, and sika deer make up most of a Siberian tiger’s diet. These are large, heavy animals. A tiger that regularly kills 300-pound prey needs the strength and mass to match it. Smaller tiger subspecies, like the Sumatran tiger, hunt smaller prey and stay leaner as a result.
A well-fed tiger can eat up to 60 pounds of meat in one sitting, then go days without another meal.
Largest Siberian Tiger Ever Recorded
Largest Verified Wild Siberian Tiger
The heaviest confirmed wild male on record through the Siberian Tiger Project weighed 212 kg (467 pounds). This tiger was radio-collared and weighed directly by field biologists, making the number reliable.
Largest Captive Siberian Tiger
The record for captivity belongs to a male named Jaipur, who reportedly weighed 423 kg (932 pounds) and measured 3.32 meters (10.9 feet) long. He lived under human care with unlimited food, which explains the extreme size compared to wild tigers.
Siberian Tiger Growth: From Cub to Full Size
Siberian Tiger Cub Size at Birth
Newborn cubs weigh just 1 to 1.5 kg (2 to 3 pounds) — smaller than a housecat. They’re born blind and completely dependent on their mother for the first few weeks.
Growth Timeline by Age
Cubs grow fast. By 6 months, they’ve started eating solid meat and gained significant weight. By 18 months, young tigers become far more independent and can hunt small prey on their own, though they still aren’t full-grown.
When Does a Siberian Tiger Reach Full Adult Size
Full skeletal and muscular maturity arrives around 4 to 5 years old. Before that age, even a large-looking subadult male hasn’t reached peak weight or skull development. This is why some captured “record” tigers in older reports were actually young adults, not full-grown ones — a detail that skews historical averages lower than they should be.

Siberian Tiger Size FAQs
How Big Is a Siberian Tiger Compared to a House Cat?
A Siberian tiger can weigh more than 100 times as much as an average house cat and measure nearly six times longer, making the difference in size enormous.
What Is the Heaviest Siberian Tiger Ever Weighed?
The heaviest verified wild male weighed 212 kg (467 pounds). The heaviest captive tiger, Jaipur, reportedly weighed 423 kg (932 pounds).
Do Male and Female Siberian Tigers Differ Much in Size?
Yes. Male Siberian tigers are much larger than females, typically weighing 100–150 pounds more and having a noticeably longer, more muscular build.
Is the Siberian Tiger Really the Largest Tiger Subspecies?
The Siberian tiger is widely considered the largest tiger subspecies, although Bengal tigers can be very close in size. Verified measurements show significant overlap between the two.
How Much Bigger Is a Siberian Tiger Than a Bengal Tiger?
The difference is smaller than many people assume. Modern measurements show that Siberian and Bengal tigers overlap considerably in weight and length, rather than one consistently being much larger.
Can a Siberian Tiger Beat a Lion in Size?
Yes, on average. Male Siberian tigers can outweigh male African lions and are generally longer from nose to tail, although individual size varies considerably.
Why Do Some Old Records Claim Siberian Tigers Over 800 Pounds?
Most claims of Siberian tigers weighing more than 800 pounds come from unverified hunting stories, estimates, or measurements of stretched skins rather than reliable scale-confirmed weights.
