The Legend of Zelda: Tears of the Kingdom is Nintendo’s biggest Switch game ever based on its file size, surpassing the previous game, Breath of the Wild, and every other Switch game from Nintendo.
Reddit user bob4978135 (via VGC) discovered that Tears of the Kingdom has a file size of 18.2GB, which makes it the biggest Switch game of all time made by Nintendo. For comparison, the biggest Switch game from Nintendo currently is Breath of the Wild (14.4 GB).
Looking beyond Nintendo’s own games, VGC reminds us that many third-party titles are much larger in size, including Mortal Kombat 11 (32.5 GB), The Witcher 3 (31.5 GB), and NBA 2K23 (53.7 GB). The Switch has 32 GB of internal storage.
