Ok, makes sense.
Grizzly bears are very variable in size. There's the normal individual variation, and males are bigger than females -- but the Alaskan population is significantly larger than the lower-48 types.
I'm aware, I'm from Montana, and Grizzlies are a very real presence hereabouts.
Hmm. According to Our World, Ogres are 8 to 12 feet tall, and they have it. If ogres are built like really burly humans (as I had thought), an 8-foot ogre wouldn't weigh 1000 pounds, more like 500-600.
Uh...not really. At 8' sure, but not at 10 to 12 feet, and I always got the impression anything under 10' is short for an Ogre.
A good rule of thumb on height/weight numbers is to cube the height in feet, and have that be the weight in pounds. This results in someone fairly hefty for that height (125 lbs. for 5' tall, 216 lbs. for 6' tall, 343 lbs. at 7' tall, and 512 lbs for 8'...just for example), but that's actually very appropriate for the thuggish build of an Ogre Going by that, a 10 foot Ogre comes in at exactly 1000 lbs.
Anyway, it's not a exact science, I admit. 1000 lbs is just right about where I draw the line, but it might be doable for some creatures at a bit lower. On the other hand, it seems to me like people have looked at Hulking Size and then give it to everyone who's even a bit above human-sized, which is an even bigger mistake. After all, Tigers can get up to 500 or 600 lbs, but I certainly don't think they should be suffering any Stealth penalties, do you?
