My lift is 14' tall. It has 2' extensions at the top of each post. It won't lift a car any higher that a 12' lift but it will allow you to run up a tall vehicle like a van without hitting the cross bar at the top. For the vast majority of cars a 12' lift will work great.It does appear the 2 post ones with the crossbar at the top seem to be right at 12' tall. Most of the shorter ones have the crossbar on the floor, which doesn't seem like as sturdy of a design.
