If we assume that 16:9 screens are the most common aspect ratio, and that
the font we use is 1:2 (which is just guesswork, based on the 8x16 console
font), that gives us a 32:9 aspect ratio counted in characters.

It seems sensible to stick to an integer multiple of that, to avoid any
uncomfortable stretching or scaling. The 480x135 console you got follows
that idea - it's the 15x scale. That's obviously a bit optimistic, but how
about the 3x or 4x scale, at 96x27 or 128x36?
