Sarah H.: There are 12 slots, 6 on each side of the wallet. There are slightly larger slots at the bottom on each side that can fit at least a few credit cards (and froyo punch cards!). There are also 4 longer horizontal slots for cash (2 on each side). For a little wallet there are TONS of storage options.
Sarah H.: Not sure what you mean by a "standard purse" but it's a pretty slim wallet! It fits well in most of my cross body bags and shoulder bags. Too large to fit in anything like a clutch or small bag
