How to maximize lenght of product title on upsell products?

Hello,
Great Plugin guys!

I need to maximize the length of product titles, i dont care if the photo will be smaller, because my product titles are big so the clients need to see more lines of the product title..
Can you tell me CSS how to do this?
PS. i notice that in mobile view all the product title is showing, i guess because its one product there..

Thank you
Kostas
