Only 6 boxes (users) simultaneously on the screen of tablet

I noticed that on tablets (android, ipad, etc.), in the card view, I can see only 6 panels (users) simultaneously on the screen, and I have to scroll the screen to see the remaining users.
The smartphones do the panels smaller in order to show up to 8 (if not more) users simultaneously on the screen! How is this possible? The screen of the tablet, as it is larger, should allow me to see simultaneously more people, but it is worse! Can it be solved? Thank you.
