The covers is the very reason they need to be thin. Seems circular perhaps. But you really don’t want the bare metal/glass to be the thing taking a hit when you drop your phone. And lots of people like to personalise their phones with those covers.

So having phone+cover being the ideal size is realistically what will be best for most people.

That may leave the bare phone a bit on the thin side, but that’s a necessary trade-off.

You can also combine phone and wallet and still have it be a nice and reasonable thickness.
