Adult mountain lions are large wild cats that typically reach 6 to 8 feet in total length (nose to tail) and roughly 70 to 220 pounds, with males larger than females. Males are usually around 7 to a little over 7.5 feet long and 130 to 220 pounds, while females are closer to 6 to 7 feet long and 60 to about 140 pounds.

Basic size overview

  • Adult males: commonly 7 to 8 feet from nose to tail.
  • Adult females: commonly 6 to 7 feet from nose to tail.
  • Weight range overall: about 60 to 220 pounds, with males at the upper end and females toward the lower to middle part of that range.

Body measurements

  • Body length (excluding tail) is roughly 3 to 4 feet, with tails adding another 2.5 to 3 feet.
  • Shoulder height is around 25 to 30 inches, so a standing mountain lion’s back is roughly at an average adult’s mid‑thigh.
  • Males tend to have heavier, more muscular bodies and larger heads than females of the same length.

Size differences by region

  • Mountain lions living in colder, higher‑latitude regions tend to grow larger than those closer to the equator.
  • Even within one state or region, prey availability and habitat quality can influence average weight and overall condition.
