Change Badge font size or badge size overall?

Configuration Frontend

I am looking for a way to make the new badges bigger. Either by changing the font size or increase the badge size overall (let’s call it upscaling). How is this possible?

I found some examples with card-mod and styles, but when using the code nothing is changing overall. I guess the code is for the old badges since it was postet some years ago. Even ChatGPT is no help.

Is there any method to do this?

Using HA 2024.9.0. Card-mod is working properly since I can change text colors on other cards.

My badge code:

type: entity
show_name: true
show_state: true
show_icon: true
entity: sensor.gelbe_tonne
color: yellow
show_entity_picture: false
name: Gelbe Tonne
visibility:
  - condition: numeric_state
    entity: sensor.gelbe_tonne_daysto
