Does anyone how I can make my product grid smaller?

[BeansReborn]

The first image (with the large product view) is mine, I'd prefer my product grid to be smaller just as shown in the other image (you can see multiple products at  once). In my mobile layout I already changed the number of colulmn to 2 but still no defferent. Also I have only one product so I'm not sure if that's the reason.

Hopefully someone knows more about this.
