Depending on the game and the stakes, I at times cap the buy in, other games, I do not. Chip amounts are based on a few factors. All the games I host are NL. Once in a while, PL.

If I host a smaller stakes game, say anything from $1/2 to $2/5 blinds, I typically cap the buy in at $300. People buy in for the max. I'll have a full table of 9 to 10 players all night)

If I host a game with $5/10 or $10/20 blinds, I don't cap the buy in. People buy in for anywhere from 100 to 300X the BB, at times, more, depending on the players.

That being said, what ever the buy in is, I need enough chips to cover all players in low and larger denoms. Typically, in the smaller game, I'll just put $1's and $5's out on the table and when people start rebuying, I furnish rebuys in $25. If someone buys in for $200, I'll give them $180 in red and $20 in white ($1's)

For the other game, I'll do reds and greens. And at rebuy time, typically just greens or black.

What I want, is enough chips on the table for the players, enough smaller denoms that players are not constantly making change with one another, and, for the players that like it, big stacks, lots of chips.

Other players who have a preference, (one guy in my games for example) buys in for $500 and only wants a stack of green. There is always enough red on the table for him to make change for his blinds.

So based on your group, number of players, etc, figure what the buy ins are, the number of chips per person, X number of players to get started and then figure rebuys into that, with either the same denom chip, or a colored up chip.

I'm sure there are 100 different ways to get to that number, but that's what I've found to work best for me.
