Migrating to a 7 inch RPI Screen and Tile Sizing For The Dashboard

Hello fellow Hubitations....I am setting up a Raspberry PI kiosk using Chilipie-Kiosk OS. What is the best way to size the tiles to fit on this smaller screen? I am using a PC right now to navigate the dashboard. Any help appreciated. Thank you.

Quickest way might be to set the grid height and width to zero and let it auto-size:

Thanks....I will give it a try....much appreciated...

I have an old 7inch tablet and these work for me:
col width 20, row height 12
90 cols, 36 rows, 12 font, gap 8

This will allow the tiles to reach edge to edge.

Thanks.... will try that also....
