Baby Registry Help

We built our registry for our first baby and I’m not sure if it is big enough. We are having 2 showers, one that will be around 20 people and one that will be 40+ people. I have about 100 items now, many cheaper items $10 or less (some of these are multiples of things too not 100 different things). Ideas of how many item we should shoot for so people have options?
