Here's a breakdown of Smilodon's size:
* Length: Around 8 to 10 feet long, not including the tail
* Height: 3 to 4 feet tall at the shoulder
* Weight: Between 800 and 1,200 pounds
So, Smilodon was a large, powerful predator, comparable in size to a modern lion.
Important Note: There were many different species of saber-toothed cats, and their sizes varied. Some were smaller, like the Homotherium (around the size of a wolf), while others, like the Megantereon, were larger than Smilodon.
