Kingdom Hearts Switch Storage & Internet Needs

Updated 7 November 2026 · Standard formula, shown below

Kingdom Hearts games on Nintendo Switch require between 10 and 40 GB of free storage per title, depending on which collection you install, and they need a stable internet connection of at least 10 Mbps for the cloud versions to play smoothly. The three collections—HD 1.5+2.5, HD 2.8, and Kingdom Hearts III—are all cloud-based on Switch, meaning the actual game files run on remote servers and your console only streams video and sends inputs. This article explains exactly how much space and speed you need, how cloud gaming works on Switch, and what to check before you buy.

Why Kingdom Hearts on Switch Is Cloud-Only

Unlike most Switch games that download and run directly on the console, the Kingdom Hearts collections were released as cloud versions in February 2022. Instead of installing the full game, you install a small client (usually under 100 MB) that connects you to a remote server running the game. The server renders each frame and streams it to your Switch over the internet, while your button presses are sent back. This approach lets the Switch play games that would otherwise be too demanding for its hardware, but it makes storage and internet speed the two most important factors for a good experience.

Exact Storage Requirements for Each Collection

Here are the storage sizes you need to install on your Switch for each Kingdom Hearts cloud release:

Kingdom Hearts HD 1.5+2.5 ReMIX (cloud) – about 10 GB
Kingdom Hearts HD 2.8 Final Chapter Prologue (cloud) – about 10 GB
Kingdom Hearts III (cloud) – about 10 GB

These sizes are for the client app that launches the stream. The actual game data never touches your console, so you do not need extra space for the full game. However, you should have at least double the listed size free (so 20 GB per game) because the Switch often needs temporary space for updates and save data. If you buy all three collections, plan for roughly 30 GB of free space total, but leaving 40 GB free is safer.

Internet Speed Requirements for Cloud Gaming

Nintendo recommends a download speed of at least 10 Mbps for cloud versions, but that is the bare minimum. For a smooth experience with minimal lag and blur, you should aim for 25 Mbps or higher. Upload speed matters too, but much less—2 to 5 Mbps is usually enough because your inputs are tiny packets. Latency (ping) is actually more important than raw speed. A 10 Mbps connection with 100 ms ping will feel worse than a 5 Mbps connection with 20 ms ping. The ideal latency for cloud gaming is under 40 ms; anything above 80 ms will cause noticeable input delay, making combat and reaction-based sections frustrating.

How Much Data Does Streaming Use?

Streaming a game like Kingdom Hearts III in 720p uses roughly 5–10 GB per hour. At 1080p (which the Switch does not support in handheld mode, but can in docked mode), that rises to 10–15 GB per hour. If you have a data cap, this matters. A 10-hour play session could consume 50–150 GB, which would blow through many home internet plans. There is no offline mode—you must be connected the entire time, and if your connection drops, the game pauses and may kick you back to the title screen.

Comparing Cloud vs. Physical/Digital on Other Consoles

On PlayStation and Xbox, Kingdom Hearts games are native downloads. For example, Kingdom Hearts III on PS4 requires about 40 GB of storage, and the HD 1.5+2.5 collection is around 30 GB. Those versions do not need an internet connection after downloading. On Switch, the cloud versions trade that large storage requirement for a constant internet dependency. If you have a slow or unstable connection, the Switch cloud versions are the worst way to play these games. If you have fast, unlimited internet, they work well enough, but you still cannot play during a commute or on a plane.

Common Problems and How to Avoid Them

The most frequent issues players report with cloud versions are:

Frequent disconnects – caused by unstable Wi-Fi. Use a wired LAN adapter if possible, or sit close to your router.
Blurry visuals – the stream automatically lowers resolution when bandwidth drops. A faster connection fixes this.
Input lag – worsened by high ping. Choose a server close to you (the game usually picks automatically) and close other apps that upload data.
Data overage – monitor your usage if you have a cap. The Switch has a data usage meter under System Settings → Data Management.

Before buying, test your connection with the built-in internet test on the Switch. If your download speed is under 15 Mbps or your ping is above 60 ms, expect a poor experience.

Frequently Asked Questions

Can I play Kingdom Hearts on Switch without internet?

No. All three Kingdom Hearts collections on Switch require a constant internet connection. If your connection drops, the game pauses and you may lose unsaved progress. There is no offline mode or download option.

How much storage do I need for all three Kingdom Hearts games on Switch?

Each cloud client is about 10 GB, so 30 GB total. However, you should have at least 40 GB free to account for updates and save data. If you have a microSD card, install them there to avoid filling up internal storage.

Is 10 Mbps fast enough for Kingdom Hearts cloud on Switch?

It is the minimum required, but it will likely result in occasional blur and lag. For a consistent 720p stream, 25 Mbps is recommended. If your connection also handles other devices, you need even more.

Does the Switch version of Kingdom Hearts III include all DLC?

The cloud version of Kingdom Hearts III includes the Re Mind DLC, which is not included in the base game on other platforms. However, the Switch version is the same as the “All-in-One” package, so you get the full story content.

Can I use a mobile hotspot for cloud gaming?

Technically yes, but most mobile plans have high latency and data caps. A 5G hotspot with low ping and unlimited data could work, but 4G will likely be too laggy and use too much data quickly.

Do I need Nintendo Switch Online to play Kingdom Hearts cloud?

No, you do not need a Nintendo Switch Online subscription to play the cloud versions. The game itself uses your internet connection, but does not require the paid online service.

Alternatives to the Switch Cloud Version

If your internet is not up to the task, consider playing Kingdom Hearts on a different platform. The games are available natively on PlayStation 4, PlayStation 5, Xbox One, Xbox Series X/S, and PC (via Epic Games Store). These versions require large downloads (30–40 GB each) but play without any internet dependency. If you have a gaming PC or a PlayStation, that is a better option for a stable experience. On Switch, there are no other ways to play Kingdom Hearts—no physical cartridges or native downloads exist.
