It's about 12 inches from the bottom of the lower suctions to the center of the top suctions, so be sure to account for that when measuring car jumping height. And it's large enough for my boy to jump up comfortably, he weights 12-13 pounds

It holds my fat girl(shes almost 18lbs) and I was scared to put her on something that seemed so thin and weak but it's holding her fat self up! She loves to be up high so I knew she’d love it

It fits nicely on smaller windows and even has little spots to put treats. Cats love this.
