How big is a grizzly bear paw?

Wolves' paws are generally around 4 inches in diameter when splayed. The largest wolves will reach or exceed 5 inches. When closed, however, they're much smaller, typically an inch and a half to two inches across the toes, although it varies a bit depending on the size of the individual wolf.
