Dang big, I would say. Seen several in the woods and killed one but none of them approached this size....maybe not even two of the ones I have seen combined was this big.
Besides the obvious fat roll and belly sag, two other things stand out to me. That grass he is standing in looks like it may 6" tall, or more, which puts him 3 feet tall at the withers. Second, the overall body profile is nearly square rather than oblong. Big bear.
Pictures can be deceiving and I won't guess a weight but my take is that you would be crazy to pass that one up hoping to see a bigger bear.
