What is the ideal raise size on the preflop?

[romerim]

A lot depends on the circumstances, but in general, from 2.2x to 3x.

little information, what stack do we and our opponents have? moreover, a lot depends on the opponents, if the opponent is ready to call with a marginal hand and a larger size? is he ready to play with such a multipot hand? as for me, the further our position, the larger the size of the open raise!

Many places mention the '3BB plus +1BB for each player entering' procedure . Of course, this is not a requirement, it is possible to raise a bigger one, but an uncomfortably big raise will not 'elegant' I think... If you want to raise big, go all-in, but I don't think you should raise for e.g. 25BB.
