For every size category a 2-handed weapon is larger than appropriate for its wielder, it gains 5 ft. of additional reach.
What do ya think?
My reasons for making this houserule - common sense dictates that when a weapon is longer, its reach should also be longer. I know there are justifications and explanations why it doesn't, but I don't buy them. Also, it gives people who insist on using bigger weapons, even if it's actually suboptimal, some additional benefit, and feats like Monkey Grip/Lighten Weapon become somewhat better.
