Sensor Card Height Different Than Button Card Height

I’ve found that the THERMOSTAT card is cumbersome to use on my tablet.
I’m striving to use standard Lovelace cards and so far have achieved the following using Tablet Mode:

However, I’m finding that my sensor cards are significantly shorter than my button cards.
Which surprised me because all the other cards align pretty well.

Any ideas?

type: horizontal-stack
cards:
  - type: vertical-stack
    cards:
      - type: sensor
        entity: sensor.home_temperature
        detail: 1
      - type: sensor
        entity: sensor.thermostat
        hours_to_show: 0
        detail: 1
  - type: vertical-stack
    cards:
      - type: button
        tap_action:
          action: call-service
          service: script.temperature_up
          service_data: {}
          target: {}
        icon: hass:plus
        hold_action:
          action: none
        show_name: false
        show_icon: true
      - type: button
        tap_action:
          action: call-service
          service: script.temperature_down
          service_data: {}
          target: {}
        icon: hass:minus
        hold_action:
          action: none
        show_name: false
        show_icon: true

This is normal. If you want to control the height of your cards, you’ll have to move towards custom solutions.
