Reraising?

If you have position, a strong hand (eg. tptk or 2 pair) and there is a raise in front of you, how much should you reraise as a % of pot or based on the size of the raise in front of you? (this is assuming a situation where reraising is the correct play)

Pre flop? post flop? how much was the bet? how big is the pot? What are the stacks? Do I wanna win the hand right now or milk em a little?

Pre flop I believe that x3 (the bet not the pot) is standard. Post flop I don't know depends on the above factors I probs need to work on this myself.

Either Pre or post flop, initial bet size around pot or close to pot, not some donk minbet.

As a default I usually just raise pot. There will be some situations in which betting smaller or larger are better but I encourage raising around pot for now.
