Reddit user bob4978135 noted that the Japanese eShop entry for Tears of the Kingdom shows that the game’s total file size is 18.2GB.
It should be noted that this is only the biggest first-party Nintendo game, and not the biggest Switch game in general.
There are a number of third-party Switch games that still dwarf Tears of the Kingdom in terms of file size, the most notable being NBA 2K23 which takes up 53.7GB.
Earlier this week, Nintendo released an extensive new gameplay trailer for The Legend of Zelda: Tears of the Kingdom.

The video debuted during a Nintendo Direct broadcast on Wednesday, followed by confirmation that the game will retail for $70, the first time Nintendo is charging more than $60 for a standard Switch game.
Nintendo’s description for the game reads: “In this sequel to The Legend of Zelda: Breath of the Wild, you’ll decide your own path through the sprawling landscapes of Hyrule and the mysterious islands floating in the vast skies above.
“Can you harness the power of Link’s new abilities to fight back against the malevolent forces that threaten the kingdom?”
