Before downloading Honkai: Star Rail, one of the first things players should check is storage space.

If you are trying to install the game for the first time, return after a break, or prepare for a new update, this guide explains how much storage Honkai: Star Rail takes and how much free space you should keep available.

Honkai: Star Rail: How Much Storage Does It Take?
Honkai: Star Rail is one of the biggest modern anime RPGs in terms of content, and that also means it can take up a serious amount of storage. The exact size depends on your platform, installed voice-over languages, downloaded resources, update files, and whether you are installing the game fresh or patching an existing version.
As a general rule, players should expect Honkai: Star Rail to need much more space than the first download screen shows. The initial launcher or app download is usually smaller, but the game expands after it downloads additional resources. This is why some players are surprised when the game appears to need dozens of gigabytes after installation.
Honkai: Star Rail Storage Size by Platform
The current storage size can vary from update to update, but these are realistic storage expectations for most players:
| Platform | Expected Storage Needed |
| PC | Around 80 GB or more |
| Android | Around 35–45 GB |
| iOS | Around 35–45 GB after full resource download |
| PlayStation 5 | Often larger than mobile and can exceed 90 GB depending on version and installed data |
These numbers should be treated as practical estimates rather than permanent limits. Honkai: Star Rail receives frequent updates, and each major version may add new maps, missions, events, characters, cutscenes, and combat content. Because of that, the game size can increase over time.
How Much Storage Does Honkai: Star Rail Take on PC?
On PC, Honkai: Star Rail is usually the largest or one of the largest versions of the game. Players should keep at least 80 GB of free space available, and having 90–100 GB free is safer if you want to avoid installation or update issues.
The PC version includes high-resolution assets, full environments, character models, battle animations, story content, audio files, and temporary update files. Even if the final installed size is lower than your total free space, the launcher may still need extra room while downloading, extracting, and replacing files.
If your PC storage is almost full, the game may fail to update even if it looks like you technically have enough space. For smoother updates, try to keep a buffer of at least 10–20 GB above the current game size.
How Much Storage Does Honkai: Star Rail Take on Android?
On Android, Honkai: Star Rail usually takes much more space than the app store download suggests. The first download may look manageable, but once you open the game, it will download additional resources.
Most Android players should prepare around 35–45 GB of free space for the full game. If you install extra voice packs or keep older cached resources, the size may be higher.
For Android users with 64 GB phones, Honkai: Star Rail can be difficult to manage long-term. A 128 GB phone is much more comfortable, especially if you also play other large games, record videos, or store many photos. If your device has expandable storage, remember that some game data may still need to stay on internal storage, depending on your phone model and system settings.
How Much Storage Does Honkai: Star Rail Take on iOS?
On iPhone and iPad, the listed app size is only the starting point. After opening Honkai: Star Rail, the game downloads additional files, including story content, assets, voice data, and update resources.
Most iOS players should expect the full game to take around 35–45 GB after installation. The exact size depends on your selected language packs and downloaded resources.
If you are playing on a 64 GB iPhone, storage can become a problem quickly. iOS system data, photos, videos, apps, and cached files can take up a large part of your device before the game is even installed. For a better experience, a device with 128 GB or more storage is strongly recommended.
How Much Storage Does Honkai: Star Rail Take on PlayStation 5?
The PlayStation 5 version can take a large amount of space, especially after multiple major updates. Players should prepare at least 90 GB of free space, and more is recommended if you want to avoid problems during future updates.
Console versions may store game assets differently from PC or mobile, which is why the size can feel surprisingly large. Since PS5 storage is also shared with other major games, it is worth checking your console storage before starting a new Honkai: Star Rail update.
If you do not have enough room, deleting older games you no longer play, moving games to external storage, or upgrading your console storage can help.
Why Is Honkai: Star Rail So Big?
Honkai: Star Rail takes a lot of space because it is not just a small turn-based RPG. It includes cinematic story scenes, detailed environments, high-quality character models, animated ultimate attacks, voice acting, music, event content, and multiple worlds.
Every major update can add more content. New areas, story chapters, enemies, bosses, mini-games, characters, and limited-time events all increase the amount of data stored on your device.
Voice-over packs are another major reason the game can become large. If you install multiple voice languages, your total file size can increase significantly. Players who only use one voice language can usually save space by removing unused packs if the game settings allow it.
Why Does the Download Size Look Smaller at First?
Many players notice that the first download size looks much smaller than the final installed size. This happens because the initial download is often only the launcher, base app, or first package. After that, Honkai: Star Rail downloads additional in-game resources.
The game may also need temporary space during updates. For example, a patch may require extra storage to download compressed files, unpack them, verify data, and replace older files. After the update finishes, some temporary files may be removed, but you still need enough free space during the process.
This is why it is always better to have more free storage than the game seems to require.
How to Reduce Honkai: Star Rail Storage Size
If Honkai: Star Rail is taking too much space, there are a few ways to reduce the storage load.
First, check whether you have multiple voice-over languages installed. Removing unused voice packs can save several gigabytes.
Second, clear cache if your platform allows it. Some temporary files may remain after updates or resource downloads.
Third, delete and reinstall the game if the file size seems unusually large. A fresh installation can sometimes remove old or unused update files. However, make sure your account is properly linked before uninstalling.
Fourth, avoid downloading unnecessary resources if the game gives you that option. Some games allow players to manage past quest resources, language packs, or optional files.
Finally, keep your device storage clean. Delete unused apps, old screenshots, videos, and files before downloading a major update.
How Much Free Space Should You Keep for Updates?
For PC, keeping 90–100 GB free is a safe target. For Android and iOS, try to keep at least 45–50 GB free if you want the game to install and update smoothly. For PS5, keeping over 100 GB free is a good idea, especially before major version updates.
Even if the game currently takes less than that, future updates can increase the size. Having extra space prevents failed downloads, slow patching, and repeated installation errors.
Is Honkai: Star Rail Worth the Storage Space?
For players who enjoy story-driven RPGs, turn-based combat, character collecting, and regular updates, Honkai: Star Rail is absolutely worth the storage space. The game offers a large amount of content, including main story chapters, side quests, events, simulated combat modes, character builds, and team strategy.
However, if you are playing on a low-storage phone, you may need to manage your device carefully. Honkai: Star Rail is best experienced on a device with enough free space to handle both the current installation and future updates.
Final Answer: How Much Storage Does Honkai: Star Rail Take?
Honkai: Star Rail currently requires a large amount of storage across all platforms. PC players should prepare around 80 GB or more, mobile players should expect around 35–45 GB after full installation, and PS5 players may need 90 GB or more depending on the version.
The safest approach is to keep extra space available before downloading or updating the game. Since Honkai: Star Rail continues to grow with new versions, characters, maps, events, and story content, its storage size will likely keep changing over time.
