    "Graphics programs use square pixels. If you set the dimensions of a graphic to 720 x 480 pixels (the NTSC frame size), you will notice that the drawing area of the graphic in the graphics program is not a 4:3 aspect ratio (it is a bit short). If you set a graphic to PAL dimensions (720 x 576 pixels), the drawing area you see in your graphics program is taller than 4:3.

    Anything you put in the graphic will be distorted (either vertically stretched or compressed, depending on your video standard) when viewed on a video monitor. If you draw a square, it will look like a rectangle. In some cases, the distortion is not great enough to worry about, but in most cases you should build your graphics with the distortion in mind.

    To compensate for pixel differences between graphics and video, you need to build the graphics at one size and then rescale them to the appropriate video dimensions, as shown in the following table."
