You’re hyped to jump into Honkai Star Rail’s latest update, explore new worlds, or try out that newly released 5-star character you’ve been saving for, only to get hit with a “not enough storage” error right when you hit download. If you’ve ever found yourself asking how much gigabytes is Honkai Star Rail, you’re not alone. I’ve had friends panic when they saw the initial 8GB download only to find they needed another 12GB of in-game assets before they could play, so it’s easy to get caught off guard if you don’t plan ahead. This guide breaks down the exact storage requirements across every platform, what causes the game to take up more space over time, and simple fixes to free up space without losing your progress.
How much gigabytes is Honkai Star Rail across all platforms?
The exact storage size depends on what platform you play on, and whether you’ve installed optional assets like extra voice packs or high-resolution textures. As of the latest version, the base game with standard assets takes up 28GB on PC, 18GB on Android, 20GB on iOS, and 32GB on PlayStation 5. Keep in mind these numbers are for the full, fully installed game, not the initial launcher download you get from app stores or the official website. Always reserve at least 30% extra space than the listed download size to avoid installation errors, especially when you’re installing a large version update. For example, if you play on PC, you’ll want at least 36GB of free space before starting the install, to account for temporary files used during the setup process. If you only have exactly 28GB free, the install will almost always fail partway through, forcing you to start over and waste time and data.
Mobile players should note that iOS tends to require slightly more space than Android for the same game build, because of how Apple’s operating system stores app data. If you have an older phone with only 64GB of total storage, you’ll need to be more intentional about what other apps you keep installed to make room for the game. PlayStation 5 users also get the highest quality texture packs by default, which explains the larger base size compared to PC, even if you don’t opt into any extra assets.
What makes Honkai Star Rail take up more storage over time?
If you’ve had the game installed for a few months, you might notice the storage size is way bigger than it was when you first downloaded it. That’s normal, and there are a few common reasons for the extra space usage. First, every version update adds new story chapters, characters, maps, and event content, usually adding between 2GB and 5GB of space each time. Unused voice packs are one of the biggest hidden storage hogs for most players. A lot of people accidentally install multiple voice languages when they first set up the game, and each full voice pack adds between 3GB and 4GB of extra space. If you only ever play with English voice acting, you don’t need to keep the Japanese, Korean, and Chinese packs installed.
Cached temporary files are another culprit: the game stores old event assets, preview videos, and temporary download files in your cache, which can build up to 2GB or more over time, even if those events are no longer available to play. If you use the in-game screenshot or recording tool, those files are also stored in the game’s folder by default, adding more space usage the longer you play. Some players don’t realize they have 100+ screenshots saved in the game’s local files, which can take up an extra 1GB or more without them noticing.
Easy tips to reduce Honkai Star Rail storage usage without losing progress
You don’t have to uninstall the game or delete your save data to free up space, there are simple, safe tweaks you can make to cut down on unnecessary storage usage. All of these tips work across every platform, and none of them will impact your account progress, since all your save data is stored on HoYoverse’s cloud servers, not your local device.
All of these changes take less than 5 minutes to do, and you’ll see the storage difference immediately. Never manually delete game folders unless you're planning to uninstall the full game, as this can corrupt your install and force you to re-download the entire game from scratch. Always use the in-game tools to manage assets, since they’re designed to only remove files you don’t need, and won’t touch core game files required to run the game properly.
What to do if you still don’t have enough storage for Honkai Star Rail
If you’ve tried all the storage reduction tips above and still don’t have enough space to install the game or its latest update, there are a few workarounds you can use. First, go through your device and uninstall any apps or games you haven’t used in the last 3 months. Most people have at least a few apps they downloaded for a trip or a one-time use that they never deleted, which can free up 5GB or more of space. Version updates for Honkai Star Rail are released every 6 weeks, so you'll need extra free space every few months to keep playing, so it’s a good habit to clean up your storage every couple of months to avoid last-minute panics before an update drops.
If you really don’t want to delete any other files, you can use cloud gaming services to play Honkai Star Rail without downloading the full game. Cloud gaming options for Honkai Star Rail usually only require 100MB or less of local storage for the app itself, though you will need a stable, high-speed internet connection to avoid lag or disconnections while playing. For PC players, you can also upgrade your storage with an affordable external SSD, which gives you hundreds of extra gigabytes of space for all your games for less than the cost of a 5-star pull on a limited banner. It’s a solid investment if you play a lot of large modern games, and you won’t have to worry about storage limits for years.
At the end of the day, the answer to how much gigabytes is Honkai Star Rail varies a lot based on your platform, the assets you have installed, and how long you’ve been playing the game. Plan for at least 20GB of space for mobile, 30GB for PC, and 35GB for PS5 to be safe, and use the simple storage reduction tips we shared to free up extra space whenever you need it. You don’t have to skip out on the latest updates or new character drops just because you’re low on storage, a few small tweaks are all you need to keep playing without hassle.
