Overview
To get the most out of textures they should be mapped in proportion to the size of the geometry. Not doing so means that different parts of the scene will have different texture distribution, resulting in some textures appearing blurrier than others while some will be overly sharp, making the scene appear inconsistent and strange. Those objects with too much texture mapped to them waste memory and cause aliasing (flickering) due to the overly high frequency of Texels.
