I notice you keep saying 4 bet, but I assume you are meaning 4 times the big blind, and if you are asking if it’s normal for people to make the bet sizing 4x the big blind pre flop…..100%.
Now, it really depends on how conservative your players are, but trust me, after a few times of playing, that pre-flop bet will regularly be in the 4x to 8x range. Easily.
I’ve played these exact stakes for about 3 years now in a home game and the $1 chip is most definitely the work horse chip, but if you like more chips on the table (which a lot of people do) get almost as many quarters as you to ones. That way you can add some spice to your bets such as a $2.75 bet for example, rather than just making it a $3 bet because you have so little fracs on the table, and people only end up using them as blinds.
A good starting set up for a $25 buy in at .25/.25 would be
.25 - 200
$1 - 400
$5 - 100
