256 color VGA mode 13h was certainly 320x200. I agree it is wrong to call it "VGA", as the VGA (Video Graphics Adapter) was able to display graphics in a variety of resolutions. The standard resolution used for games was the 256 color 320x200. VGA allowed a couple of other non-documented and harder to achieve resolutions in 256 color, but this was the standard one, and also Quake's default mode. 640x480 was 16 color. Standard text-mode VGA was 80x25 characters of 9×16 pixels for a total of 720x400 pixels. SVGA was even more diffusely defined, as different vendors supported different resolutions.
