My first thought was for the ends, and for a similar reason that the smaller diameter cans pack more densely.

If you're punching circles out of sheet metal, you'll get more waste with larger circles.

I don't think you would. The design can be scaled up or down without impacting the proportion of the area which ends up being 'useful'.

The percentage waste per circle remains the same, but the absolute amount of waste per can goes up.
