Well, letâs talk size first. Tigers are heavier, weighing up to 800 pounds to the lionâs 550. But the two cats arenât so different in size. You might remember from high school health class that muscle weighs more than fat, which helps explain the tigerâs extra pounds. So it seems that the tiger would have a physical advantage over the lion.
The largest tigers, the Siberian, also called Amur, are 10.75 feet (3.3 meters) long and weigh 660 lbs. (300 kg), according to National Geographic. The smallest tiger is the Sumatran tiger. They grow to 5 to 12 feet (1.5 to 3.7 m) and weigh 143-670 lbs. (65-305 kg), according to the Woodland Park Zoo.
