HU preflop raise sizing

[Zaghomat]

I'm playing low limit HU cash game 0.5/1 and 1/2. Most of my opponents sucks and are basicly calling every hand preflop and limping a lot on the SB.

I'm playing tight preflop like 42/36. I use the bet pot button and raise to 3bb preflop.

In this situation, would it be better to raise more preflop like 4 or 4.5BB, since they are calling anyway with worst hand most of the time?

raising to 3.5 OTB and 4.5 OOP is prob best bet, be kinda nitty about ur BB raising because they call and never fold to cbet

I just use the pot button OTB and make it 4x in the BB. If I realize they are never folding I make it 5 or 6x. And I always 3bet bigger than pot.
