What are the standard raise/re-raise/ bet amounts?

[zasterguava]

Ok I've been looking through the FAQ and see the standard pre-flop raise is 3-4 xbb and 1xbb for every limper. What's the standard for raising and 3 betting pre-flop and also post flop if there is such a standard in selective scenarios? For example, I've looked over my hands and I've noticed i've been raising I believe disproportionaly high on the turn where I would like to be raising a 'standard' % of pot. And also have not been sure of the best amount to raise on the flop HU or in multiway pots so would help to know a approximate % range of the chips to raise in any given pot size.
