We've known for a while now that the Nintendo Switch will move away from disc-based games, instead adopting cartridges similar to the 3DS, but the actual size of these carts has just been revealed. Switch cartridges are 34mm long and 23mm wide, making them even smaller than 3DS cartridges. Despite the decrease in physical size, however, the actual file sizes of Switch games are considerably larger. For example, Zelda: Breath of the Wild is 13.4GB on Switch, while Zelda: Ocarina of Time 3D is just 512MB on 3DS.
