With the Switch 2 touting a significant technical leap over its predecessor, games are naturally going to be more visually impressive, technically demanding, and, by extension, larger in size- though not too much larger, it turns out.

Nintendo has started revealing file sizes for Nintendo Switch 2 titles via their Japanese eShop pages, and though they are obviously a jump from the Switch 1, by modern standards, they remain refreshingly manageable (based on early indications, at least).

Mario Kart World is listed as having a 23.4 GB file size, in contrast to 11.3 GB for Mario Kart 8 Deluxe on the Nintendo Switch. Donkey Kong Bananzameanwhile, will have a 10 GB file size. In comparison, the dev team’s last major 3D platformer, Super Mario Odyssey, has a 5.6 GB file size.

Nintendo has also revealed sizes for upcoming native Switch 2 enhanced releases for a couple of Switch 1 titles, with Kirby and the Forgotten Land weighing 5.7 GB, which is curiously about the same as its Switch file size, and Super Mario Party Jamboree coming in at 7.7 GB (compared to 5.3 GB on Switch).

The Nintendo Classics – GameCube app, which will allow Nintendo Switch Online + Expansion Pack subscribers to play GameCube titles exclusively on the Switch 2, will weigh 3.5 GB.

Nintendo Switch 2 launches with Mario Kart World as a launch title on June 5, featuring 256 GB of internal storage. Donkey Kong Bananza releases on July 17.
