Fortnite requires between 90 and 160 GB of storage space on your PC, depending on which version you install and whether you add extra content

The base game of Fortnite takes roughly 90 GB when you first read it. However, the actual amount of space it uses grows over time as the game receives updates, seasonal content, and new map areas. If you install the full version with all available cosmetics, battle pass rewards, and Creative mode assets, you can expect the total to reach 160 GB or higher. The exact number depends on your graphics settings during installation and which optional content packs you choose to read.

Fortnite is available through two different launchers on PC: the Epic Games Launcher and Steam. Both versions take up roughly the same amount of space, though the Epic Games version is slightly smaller because it does not include Steam's own system files. If you install Fortnite on both launchers, you will need to reserve storage space for two separate copies—they do not share files.

Key Takeaways

  • The base Fortnite installation is approximately 90 GB, but seasonal updates and new content can push this to 160 GB or more over time.
  • You should have at least 200 GB of free space on your drive before installing, because the game needs room to read, unpack, and update without running out of storage.
  • Fortnite installed through Epic Games Launcher and Steam are separate downloads that do not share files, so installing both requires double the storage.
  • Uninstalling old cosmetics and seasonal content you no longer use can free up 10 to 20 GB, though the game will re-read these files if you log back in.

Why Fortnite takes up so much space

Fortnite is a large game because it stores high-resolution textures, 3D models, and audio files for every cosmetic item, weapon, vehicle, and map location. The game world itself—including all the buildings, terrain, and interactive objects—requires significant storage. Every seasonal update adds new skins, emotes, weapons, and map changes, and the game keeps older versions of these assets in case you want to use them again.

The game also pre-loads assets for upcoming seasons and events. This means you may have files on your drive for content that has not been released yet. Epic Games does this so that when a new season launches, you do not have to read everything at once and experience lag or long load times.

Storage space you actually need before installing

Do not install Fortnite if you have only 90 GB of free space. You need at least 150 to 200 GB of free space on your drive before you start the read. Here is why: the installer downloads a compressed file (usually 30 to 40 GB), then unpacks it into the full game files. During unpacking, your drive temporarily holds both the compressed file and the unpacked version at the same time. If your drive runs out of space during this process, the installation will fail and you may have to start over.

After installation completes, leave an additional 20 to 30 GB of free space on the drive where Fortnite is installed. The game uses this space for temporary files, shader caches, and updates. If your drive is completely full, Fortnite may crash or refuse to launch.

How to check how much space Fortnite is using right now

On Windows, open File Explorer and navigate to the folder where you installed Fortnite. If you used the Epic Games Launcher with default settings, the path is usually C:\Program Files\Epic Games\Fortnite. Right-click the Fortnite folder, select Properties, and Windows will show you the total size of all files inside.

If you installed through Steam, the default location is C:\Program Files (x86)\Steam\steamapps\common\Fortnite. The process is the same: right-click, Properties, and read the size. This number updates in real time, so you can check it again after a major update to see how much space the new content added.

Reducing Fortnite's storage footprint

You can free up space by uninstalling cosmetics and seasonal content you no longer use. Open the Epic Games Launcher, go to your Library, find Fortnite, click the three dots next to it, and select Manage. From there, you can uncheck optional content packs to remove them from your drive. Removing old battle pass cosmetics and seasonal items can free up 10 to 20 GB.

Keep in mind that if you uninstall cosmetics and then log into the game later, Fortnite will re-read them automatically if you try to use them. The game does this because it needs the files to display the cosmetic on your character. If you uninstall content and never use it again, the space stays free.

Another option is to move Fortnite to a different drive if your PC has multiple storage drives. Both the Epic Games Launcher and Steam allow you to choose which drive to install games on. If you have a secondary drive with more free space, you can uninstall Fortnite from your main drive and reinstall it on the secondary one.

Storage differences between Epic Games Launcher and Steam

The Epic Games version of Fortnite is slightly smaller than the Steam version because Steam adds its own system files and configuration data. The difference is usually only 2 to 5 GB, so it is not significant enough to matter for most players. Both versions play identically and use the same account system.

If you want to install Fortnite on both launchers, you will need to reserve 180 to 320 GB of total free space, depending on how much seasonal content each installation accumulates. The two versions do not share files, so they are completely separate downloads.

What to do if your drive does not have enough space

If your PC does not have 150 GB of free space available, you have a few options. First, uninstall programs and games you no longer use. Windows also has a built-in storage cleanup tool: go to Settings, System, Storage, and click Temporary Files to delete old installation files and cache data. This can free up 5 to 20 GB depending on how long it has been since you last cleaned up.

If cleanup does not free up enough space, consider buying an external hard drive or a new internal drive. A 1 TB external drive costs between $50 and $100 and gives you room for Fortnite plus other games and files. If you are comfortable opening your PC, adding a second internal drive is another option, though this requires some technical knowledge.

Frequently Asked Questions

Does Fortnite use less space on console than on PC?

Fortnite on PlayStation 5 and Xbox Series X takes up roughly 90 to 100 GB, similar to PC. PlayStation 4 and Xbox One versions are smaller, around 80 GB, because they use lower-resolution textures and assets optimized for older hardware. The difference is not large enough to make console a better choice for storage reasons alone.

Will Fortnite get smaller or larger in the future?

Fortnite will likely stay around 90 to 160 GB for the foreseeable future. Epic Games occasionally removes very old cosmetics and assets to prevent the game from growing indefinitely, but new seasons and events add content faster than old content is removed. The trend over the past few years has been slow growth, not shrinkage.

Can I move Fortnite to a USB drive or external drive and play it from there?

You can store Fortnite on an external drive, but playing from it will be slower than playing from an internal drive. External drives connected via USB 3.0 or USB 3.1 are fast enough for Fortnite to run without major problems, but you may experience slightly longer load times. USB 2.0 drives are too slow and will cause lag and stuttering.

Does uninstalling and reinstalling Fortnite free up space?

Uninstalling Fortnite completely removes all its files and frees up the full 90 to 160 GB. Reinstalling it later will take up the same amount of space again. Uninstalling does not compress the game or make it smaller—it just deletes it entirely.

Why does Fortnite keep getting bigger with each update?

Each seasonal update adds new cosmetics, weapons, map areas, and audio files. Epic Games keeps old cosmetics on your drive so you can still use them, rather than deleting them. Over time, these additions accumulate. The game does occasionally remove very old assets, but new content is added faster than old content is removed.
