Responsive way of making product descriptions same height?

I am trying to find a responsive way of making product descriptions the same height in the product catalogue page. While the below code would work on desktops, once I try it out on mobile devices, the heights become different. I could, of course, keep increasing the min-height to larger em, but I was wondering if there is a better way to do this?

.woocommerce-loop-product__title {
  min-height: 3em;
}

Thanks.
