The Amiga is notorious for changing the screen size between, or inside, games. Look out so that you don't crop overscan areas, since some games exceed the default PAL and NTSC resolutions. Do not use GIF for Amiga screens, unless you are absolutely certain that less than 256 colours are used, including rainbow effects in the background. PNG is the preferred format.

Being the predecessor of the Amiga, the Atari 8-bit computer is also prone to change the size of the screen. The above resolution should capture all the overscan area, but cropping is welcome if you get big borders at that resolution.

VIC-20 screen size varies a lot, just make sure that the aspect ratio is correct (pixels are usually twice as wide as they are tall) and that borders are not larger than necessary.
