Nintendo has quietly reduced the install size of Mario Kart World just days before the game’s highly anticipated launch on June 5, 2025. The latest installment in the iconic Mario Kart series, Mario Kart World will now require under 22 GB of storage—down from the originally listed 23.4 GB.
The update was discovered through Nintendo’s eShop listings for the upcoming Switch 2 console, which launches simultaneously with Mario Kart World. According to recent reports by Nintendo Life and verified by Game Rant, the U.S. and Japanese Nintendo eShop now reflect the smaller file size of 21.9 GB as of May 31, marking a 6.41% reduction from the prior listing.
This change was made without any official announcement from Nintendo, surprising fans and gamers worldwide. Multiple regional eShop stores, including Canada and the Netherlands, have also updated their listings to reflect the new install size.
Why This Matters
The reduced file size is a notable move considering Mario Kart World is positioned as the flagship launch title for the Switch 2. The smaller install could mean quicker downloads and less storage pressure for gamers eager to dive into the open-world racer on day one.
For many, storage space is a key concern, especially with increasingly large game files on modern consoles. Nintendo’s decision to trim down the install size may improve user experience and accessibility for a wider audience.
What to Expect on Launch Day
Mario Kart World launches exclusively on the Switch 2 on June 5, 2025. As the centerpiece of the new console’s launch lineup, the game is expected to showcase next-generation racing mechanics and expansive open-world environments.
With the file size revision out of the way, fans can prepare for a smooth download and immediate play without worrying about storage constraints.
While Nintendo has not commented on the reasons behind this last-minute file size reduction, it’s clear the company is committed to optimizing the launch experience. Whether this reflects improvements in game compression or content tweaks remains to be seen.
