Lovelace card sizing

This lovelace thingie is kinda fun and the transition is going well. Now, a noob question.
When setting up a map card for device-tracking… how do I make the standard screen card bigger. It’s only consuming less than 1/2 of my chrome display space.

One possibility would be to set one of your views to “panel: true” to make the card span the whole width.

That worked! (after I discovered the panel: had to be before the -card rather than after it.
Thank you

Hi,
I know this is an old post but does anyone know how to do this but in the UI?

Cheers

Panel mode relates to the view not the card, it dedicates the whole view to a single card (although this could be a stack, nested stacks or a range of custom cards like layout-card, stack-in-card etc.) that enable you to embed multiple cards and control the layout to a greater or lesser extent.

Anyway, to answer your question, because it belongs to the View, you need to edit the View and then there’s a switch to turn on panel mode.
