What is this? An average-sized 65 inch tv has the dimensions of 58″ wide x 32″ tall x 2″ deep.

Will a 65 TV fit in my car?

A 65-inch TV can properly fit in a real-size SUV. To store the TV properly, it must be upright (not flat) during transport to mitigate the risk of damage. A smaller car may fit a 65 inch TV, but not stored properly, and therefore shouldn’t be used.
