for the most part, just make the standard raise for the table with those hands, or 3x the BB, whichever number is larger. for example, in a lot of live casino games, many people will actually make it 5x or 6x the BB as their standard opening raise. if enough people at the table are doing that, and getting called, raising that much is fine. live poker is cuh-razy.
but you shouldn't really differ your raise sizes based on the strength of your own hand, unless your opponents are really unobservant, because you'll begin to telegraph your hands. having the same standard-sized raise for every hand you want to raise is the safest way to go
