List Tile View user thumbnail size

[Ramikin]

Hello,

Preface: I am a SharePoint novice having only moved to the platform this year... 

I have a list containing a 'person' column (titled 'Staff Email') populated with the staff members at our school. I am embedding the list in gallery view to a SharePoint page.

However, in Tile view I would like to increase the size of the user thumbnail.

With some trial and error amending the JSON data in advanced mode (bearing in mind I am a novice, and trial and error is all I have at my disposal) I have found that I need to remove "class": "sp-card-userThumbnail" [Line 58] to cause any change at all. But how do I increase the size of the circular thumbnail that is displayed?

 

See the code below that I am trying to amend. Any help and advice gratefully received.

 

I hope you can help, many thanks in advance.
