The main problem is that there are as many exceptions as there are rabbits who fit the description of a particular breed. A related issue is judging an animal by appearance rather than by personality. The fact is that there is no apartment too small for even the largest rabbit. And if there were a safe generalization to make, it would be that larger rabbits tend to be less active and therefore require less space than the dwarf breeds. Most rabbits, if they are bred intentionally, as opposed to accidentally, are bred for appearance, not personality.
Gentle rabbits have gentle faces, regardless of breed.
Worriers look worried. They rarely roll over on their backs or lie with their back legs extended behind them. Mellow rabbits lounge around any old way, dangling from your arm, in the middle of a busy room. Irritable rabbits have pinched, crabby facial expressions, just like that nasty bank teller who makes you feel like you're imposing on her when you withdraw your money from her bank. As a student of rabbit nature, these are the observations to treasure.
