I had some fun recently with this. My solution/understanding turned out to be three parts:

• Icons (svg format in my case) need to have their internal size at least as large as you are trying to do with the icon. (bizarre to me).
• In rqt_robot_dashboard, where self.max_icon_size is set in setup(); I think this dictates a "canvas" size per button on the dashboard.

• In e.g. nav_view_dash_widget.py, self.setFixedSize can scale the icons. I ended up doing (and then getting distracted by other things):

  # Old version:
  #self.setFixedSize(self._icons[0].actualSize(QSize(50, 30)))
  # New version, larger, more absolute:
  self.setFixedSize(QSize(100,60))
  

Caveat: I'm working with a derived version of rqt_dash for Fetch robots, so I've been playing with ever so slightly different code. Nor have I fully wrested control of the rqt_dashboard setup to my liking.
