Minecraft wiki entry for Pixel_art, associated text: Designs drawn that are copied from Minecraft are usually mobs or blocks, drawn so that a 1 pixel is equal to 1 block. This makes pixel art that copies Minecraft textures 16 times bigger than the mob or block. To make these even bigger, you can make 1 pixel equal to a 2 x 2 area of 4 blocks. For an absolutely giant version of a mob or block, make 1 pixel equal to a 4 x 4 area of 16 blocks. There are an infinite amount of possibilities.
