Above is the general rule of thumb for the recommended number of chips needed when playing poker. The denomination or color break up in a 4 color chip bank roll (which is the most popular one) is 70% of the chips should be at the lower and middle values: i.e. a 400 chip set would be: 100 White, 200 Red, 50 Green & 50 Black or 150 white, 150 Red, 50 Green & 50 Black.
