Shoulder height of 1 mt head and shoulder length of 1,80 mt and weight from 250 to more than 300 kgs, if you see their skeleton they were more massive than Tigers and Lions.

Shoulder height - 1 m ( 3 feet 3 inches ). Body Length - 1.8 m ( 5 feet 11 inches ). Weight - from 250 to 300 kg ( 551 pounds to 661 pounds ). Roughly the size of a lion but considerably heavier. 
First record of Smilodon fatalis Leidy, 1868 (Felidae, Machairodontinae) in the extra-Andean region of South America (late Pleistocene, Sopas Formation), Uruguay: Taxonomic and paleobiogeographic implicationsAbstract
The Felidae are known in South America from the Ensenadan Stage/Age onwards. Among them, machairodonts of the genus Smilodon stand out. Three species are recognized, and all three are present on the continent: S. gracilis from the early-middle Pleistocene in north-east Venezuela; S. fatalis, found only in Lujanian sediments on the west side of the Andes (north-west of Peru and south-west of Ecuador); and S. populator, which inhabited the eastern part of the Andes during the Ensenadan and Lujanian. This distribution has led to the suggestion that the last two felids were allopatric during the Lujanian. Here, we report the first evidence of S. fatalis in the eastern part of the continent (Sopas Formation, late Pleistocene of Uruguay), based on an almost complete skull. This finding not only enlarges its distribution in South America but questions the idea of allopatric distribution. It also adds a new component to the mammalian predator trophic level of Uruguay, with the capacity to predate large South American herbivores and megaherbivores. A revision of materials previously assigned to S. populator in the extra-Andean zone of South America will be required. Here is the skull and its measurements:  *This image is copyright of its original author Every year, it seems the Pleistocene was more and more crowded. Now South America even had two Smilodons, even though they are still considered to be geographically separated from each other (allopatric). PM for the paper.

There was this ages-old theory about how Smilodon killed with his long saber-like teeth. The story goes that he stabbed his prey with his mouth shut. Considering his massive neck and shoulder muscles ( rivaling those of a grizzly ), and considering that this method works for the only saber-toothed animal living today ( walrus )... perhaps?
On a documentary that I recently watched, it was said that Smilodon adults has very little sexual morphism. Both male and female being the same size and with the same-sized teeth. Would this suggest that Smilodon males did not fight for mates nor for territory? If so, the lifestyle of a pride of saber-toothed cats must have been very different from that of lions.

I read something like that too... https://today.duke.edu/2009/11/sabertooth.html With all the possible consequences.
