it seems a question can take up a minimum of a 3x3 grid.

Is there a limit to the number of grid boxes on a screen, i.e. can you have more than one screen worth vertically on a dashboard where you can just scroll unlimited?

is there a limit to the number of questions, cards, horizontal and vertical blocks on a dashboard, and number of dashboards in metabase? (or are all of these thing just dependent on memory).

No limits to how many cards you add to the dashboard, and it will scroll indefinitely.

We do have a limited number of horizontal grid cells.

We generally suggest you keep dashboards to a single screen’s worth or so for usability reasons. Performance wise as well, lots of cards on a dashboard have their issues as there are a limited number of connections a browser can make to a single server.
