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.
An average adult male tiger from Northern India or Siberia outweighs an average adult male lion by around 45.5 kg (100 lb). Males vary in total length from 250 to 390 cm (98 to 154 in) and weigh between 90 to 306 kg (198 to 675 lb) with skull length ranging from 316 to 383 mm (12.4 to 15.1 in).
