Resize auto entities card

Hey guys,
I am trying to resize the auto-entities card but without success so far.

I am working on yaml file, this is my code:

    cards:
      - type: 'custom:button-card'
        style:
          - width: 150px
        cards:
      - type: 'custom:auto-entities'
        card:
          type: entities
        filter:
            exclude:
            - name: Alexa*
            include:
              - state: 'on'
                domain: switch
        sort:
          method: friendly_name

Can someone help me to figure out what I am doing wrong ? My goal is to see the card smaller than the original size.

Thanks !
