The Nintendo Switch comes with 32 GB of built-in storage, but you can only use about 26 GB for games and saves

The Switch's internal storage is smaller than the number on the box suggests. Of the 32 GB total, the operating system and system files take up roughly 6 GB, leaving you about 26 GB for your own content. A single modern game can take 10 to 15 GB or more, which means you will run out of space quickly if you read more than two or three titles.

The actual space available also shrinks slightly over time as the system updates and adds features. You will see the remaining space in System Settings under System Storage, which is the most reliable way to check what you have left before downloading a large game.

Key Takeaways

  • The Switch has 32 GB total, but only about 26 GB is usable for games and saves after the operating system takes its share.
  • Most modern Switch games are 10 to 15 GB each, so you can fit only two or three without running out of space.
  • A microSD card (64 GB or larger) is the practical solution if you want to own more than a few games at once.
  • The Switch reads games from microSD cards at the same speed as internal storage, so performance does not suffer.
  • You can swap microSD cards between Switch consoles, but game saves stay on the internal storage unless you back them up separately.

Why the storage fills up so fast

Game file sizes have grown significantly. Older Switch titles like The Legend of Zelda: Breath of the Wild are around 13 GB, while newer games like Baldur's Gate 3 are 150 GB (though that requires a microSD card). Even smaller indie games often range from 2 to 8 GB. If you own a physical cartridge, the game still takes up storage space on your Switch because the console installs a copy to the internal drive or microSD card.

System updates also consume space during installation. When a major update arrives, the Switch temporarily needs extra room to read and install it, which can trigger storage warnings even if you thought you had enough space. Once the update finishes, some of that temporary space is freed, but the system itself grows slightly larger with each update.

When you actually need a microSD card

If you plan to read more than two games, a microSD card is not optional—it is necessary. The Switch supports microSD, microSDHC, and microSDXC cards up to 2 TB in size, though cards larger than 256 GB are uncommon and expensive. A 64 GB card costs around $10 to $15 and gives you room for roughly four to six games depending on their size. A 128 GB card, usually $15 to $25, holds eight to twelve games.

The Switch reads from microSD cards at the same speed as internal storage, so games run identically whether they are installed internally or on the card. The only practical difference is that you cannot play games from the microSD card if the card is removed, but you can swap cards between different Switch consoles and the games will still work.

How to check your remaining storage

Open System Settings from the home menu, scroll down to System, then select System Storage. The screen shows your total storage, how much is used, and how much is free. If you have a microSD card installed, you will see a separate line showing its capacity and usage.

Games themselves also show their file size in the eShop before you read them. If you see a game is 20 GB and your free space shows 15 GB, the read will fail. The Switch will warn you before you start, but checking first saves time.

Physical cartridges versus digital downloads

Physical game cartridges do not eliminate the storage problem. The Switch installs a copy of the game to internal storage or microSD regardless of whether you own the cartridge. The cartridge itself is just a license to play—the actual game files live on your console's storage. This means owning ten physical cartridges still requires enough storage space for all ten games if you want them installed and ready to play.

The advantage of physical cartridges is that you can uninstall the game to free space, then reinstall it later from the cartridge without downloading it again. With digital games, you must read them again if you delete them to make room for something else.

Expanding storage without losing your saves

Game saves are stored on the Switch's internal storage, not on microSD cards or cartridges. This means your progress in Zelda, Mario, or any other game stays on the console even if you remove the microSD card or swap cartridges. You can move games between internal storage and microSD card using System Settings, but saves do not move with them.

If you want to back up your saves to the cloud, Nintendo Switch Online membership includes automatic cloud backup for most games. Without the subscription, your saves exist only on the console itself. If the console fails or is lost, those saves are gone unless you have manually backed them up to another Switch.

Choosing the right microSD card size

A 64 GB card is the practical minimum if you read games regularly. It costs little more than smaller cards and gives you breathing room. A 128 GB card is the best value for most players—it holds enough games that you will not constantly delete and reinstall, and it costs only slightly more than 64 GB.

Avoid very cheap microSD cards from unknown brands. Reputable manufacturers like SanDisk, Kingston, and Samsung are reliable and not significantly more expensive. The Switch does not require a specific speed rating, so you do not need to pay extra for the fastest cards available.

Frequently Asked Questions

Can I use any microSD card in my Switch?

The Switch accepts microSD, microSDHC, and microSDXC cards up to 2 TB. Most cards sold today work fine. Avoid extremely cheap or counterfeit cards, which may fail or corrupt your data. SanDisk, Kingston, and Samsung are reliable choices.

What happens if my microSD card is full?

The Switch will not let you read a game if there is not enough space on your microSD card or internal storage. You must delete a game or move one to free up room before the read can proceed. Saves are not deleted when you remove a game.

Do I lose my game saves if I remove the microSD card?

No. Saves are stored on the Switch's internal storage, not on the microSD card. You can remove the card, swap it with another, or delete games from it without affecting your progress. Games themselves must be reinstalled if you delete them.

Can I use the same microSD card on multiple Switch consoles?

Yes, you can move the card between consoles and the games will still work. However, each console has its own save files stored internally. Your progress in a game on one Switch will not appear on another Switch unless you have cloud backup through Nintendo Switch Online.

Is 32 GB enough if I only buy physical games?

Physical games still require installation space on your Switch, so 32 GB fills up quickly if you own several games. A microSD card is still recommended unless you plan to own only one or two physical games at a time.
