A Quick Mental Picture

If you are about 5.5–6 feet tall, a large male grizzly standing up can easily tower a couple of feet above your head, with a bulk similar to a large refrigerator turned on its side.

TL;DR: Grizzly bears are big; think a 6–8 ft long, 300–800 lb animal that can stand 8–9 ft tall, with the largest males pushing close to half a ton or more.
