The original release version of Pokémon Pokopia had a file size of 6.2 GB.
The 6.2 GB figure belongs to version 1.0.0, the game’s initial release version. It is listed separately from later patches and downloadable content, so it should not be confused with the total storage space a player might eventually need after updates or expansions.
Pokopia’s physical edition uses a Game-Key Card, while the digital edition is downloaded through the Nintendo eShop. In either case, the game’s data size matters when planning storage on a Nintendo Switch 2 system or microSD Express card.
The number is also easy to confuse with sales figures reported for the game. Pokopia sold 2.2 million units worldwide in its first four days, but 2.2 million is a sales count, not a file size. Likewise, later reports mention four million and five million units sold; none of those figures describe the game’s installation data.
