How big is the biggest tiger on earth?

It's impossible to say for sure what the biggest tiger on earth was, as there are no official records of every tiger ever to exist. However, we can look at the largest recorded tigers:

* Amur tigers are generally considered the largest subspecies of tiger. The largest confirmed Amur tiger weighed 384 kg (846 lbs). This individual, nicknamed "The Big One", was shot and killed in 1936.

* Bengal tigers are the second largest subspecies. The largest recorded Bengal tiger weighed 360 kg (794 lbs). This individual was shot and killed in 1967.

It's important to note that these are just the largest recorded individuals. There may have been even larger tigers that were never measured or documented.

In addition to weight, size can also be measured by length. The longest recorded tiger was a Bengal tiger measuring 3.33 meters (11 feet) from nose to tail.

While these statistics give us an idea of the potential size of tigers, it's crucial to remember that the tiger population is in decline, and larger individuals are becoming increasingly rare.
