How big pot odds do you need to call preflop with a small pair?

If you have 22 - 55 and there's a preflop raise, and you and your opponent/opponents are deep stacked, so you have big implied odds. The odds of hitting a set or quads is about 8:1, but usually you won't need nearly that much pot odds to call since you'll probably double up later in the hand if you hit your set and your up against a big pair. So about how big of pot odds do you need?

If you are both deep stacked calling as much as 10% of your stack seems to be the rule. Pre-flop odds aren't as important in NL.
