As of April 2026, the total install size for Diablo II: Resurrected
on PC has increased to approximately 43 GB. This growth follows the release of the major Reign of the Warlock DLC and recent technical updates. Current Download & Install Sizes (2026)
Sizes vary by platform and version, especially with the introduction of new DLC content: Total Storage Required PC (Steam/Battle.net) ~43 GB Recent Steam updates have seen 25 GB patches PlayStation 5 ~25.5 GB Significantly larger than the original 2000 release Nintendo Switch ~8.3 – 8.5 GB More compact but lacks the "Legacy Toggle" for new DLC Xbox Series X/S ~30 GB+ Base game is roughly 30 GB; additional for DLC Recent Large Updates
Players on Steam recently reported a massive 24.9 GB update in April 2026. While the developer Battle.net update was much smaller (roughly 42 MB for some users), the Steam version often requires a larger re-download or verification process that can mimic the size of nearly the entire game. New Content Impacting Size
The 2026 "Reign of the Warlock" expansion added significant assets that contributed to the increased storage footprint, including: The Warlock: The first new playable class in 25 years.
New Endgame Bosses: Encounters like the Colossal Ancients and Herald.
Technical Modernization: Higher fidelity textures for 4K UHD graphics on PC.
Tip: If your Steam download seems stuck or shows an error after the 25 GB patch, verify your game files through the Steam Library properties to ensure the build isn't corrupted. Diablo II: Resurrected
Future Updates: Will the File Size Grow Again?
Blizzard has confirmed continued support for Ladder seasons through at least 2026. While new runewords and balance changes add minimal KB of data, major seasonal events (like the upcoming Christmas in Sanctuary event) may add 200–500 MB of temporary models and sound files.
Based on historical patch data, we expect the Diablo 2 Resurrected new download size to increase by no more than 2–3 GB over the next 18 months. Unlike Call of Duty, D2R does not suffer from "patch bloat" because Blizzard overwrites old assets rather than stacking them.
PC (Battle.net)
- Initial Download: Approx. 30 GB
- Total Installation Size: Approx. 35 GB - 40 GB
- Note: The game creates additional files for shaders and caches once you launch it, so always have a few extra gigabytes free to prevent stuttering.
3. Xbox Series X: Don't Download 4K Assets for 1080p TVs
Go to Settings > General > TV & Display Options. Uncheck "Download 4K content." This reduces the D2R new download size from 25.5 GB to roughly 19 GB.
The Short Answer: Current Download Size
As of the most recent updates in 2024, here are the raw numbers you need to know:
Xbox Series X/S & Xbox One
Microsoft’s consoles show a leaner footprint: 25.5 GB. Xbox users benefit from Smart Delivery, meaning you only download the assets necessary for your specific console. For example, if you play on an Xbox One S, you won't download the 4K texture pack intended for the Series X.
Nintendo Switch
- Installation Size: Approx. 25 GB - 27 GB
- The Switch version is the most optimized of the bunch. However, given the console's limited internal storage (32GB), an SD card is practically mandatory for D2R players.
A Note on "Prerelease" vs "Live" Builds
If you participated in the Technical Alpha or Beta tests in 2021, you may recall the download was under 20 GB. The modern version is larger because Blizzard has added:
- Enhanced 3D audio files (Dolby Atmos support)
- Additional Ladder-exclusive runeword assets
- Holiday-themed event data (e.g., The Darkening of Tristram)
- Anti-cheat system files (Warden)
Pro Tip for PC users: When updating, the Battle.net launcher may require an additional 30 GB of temporary free space to unpack and patch existing files. If you are constantly running out of room, ensure you have at least 55 GB free before hitting "Update."
