THE biggest Siberian tiger in the world reaches the total length of 13 feet and weighs as much as 660 pounds. The world record is held by a male wild tiger and it is the largest Siberian tiger ever recorded. However, the average weight of amur tigers is around 400 pounds. There are reports that claim much bigger amur tigers in the wild but their sources are probably too ambiguous. If the biggest amur tiger stands on two legs then it nearly reaches the size of a female giraffe. The female giraffe is just around 14 feet in height.
The Bengal tiger one that is found in the Indian Subcontinent is only slightly smaller than the Siberian tiger. The mean weight of wild amur tigers is estimated at 397 to 675 lb for males but females weigh around 220 to 368 lb. Back in the 1980s, tiger hunters claimed that they had shot Siberian tigers that would weigh up to 897 lb.
The Siberian Tiger Project claims that the average body size of amur tiger population in the Sikhote-Alin range is around 178 to 208 cm (70 to 82 in). Adult males reach the length of 195 cm whereas females average up to 167 cm. The biggest male recorded by the project team at 454 lb.
