How Many GB Is ZZZ? File Size, System Requirements & Low-Spec Guide | Zenless Zone Zero (ZZZ)
On PC, the Zenless Zone Zero (ZZZ) download is about 57 GB, but installation needs up to 110–115 GB of free space because the files are unpacked first; the installed game then takes roughly 57–71 GB. Mobile is much lighter: Android needs about 20 GB of free space and iPhone/iPad about 26 GB, while the PS5 build is around 55 GB. The minimum requirements are gentle (PC only needs a 7th-gen i5, a GTX 970 and 8 GB RAM), so a low-end machine can still run it well on Low settings.
How many GB is ZZZ on each platform?
Zenless Zone Zero's size depends on your device. The key catch on PC: the download is smaller than the space you need to install, because the game unpacks the files first and then compacts them.
| Platform | Download | Free space needed |
| PC (Windows) | ~57 GB | ~110–115 GB to install (~57–71 GB after) |
| Android | ~15 GB | ~20 GB |
| iOS (iPhone/iPad) | ~17 GB | ~26 GB |
| PlayStation 5 | — | ~55 GB |
Note: each major update (like a new version) can add tens of GB, so always keep some spare space instead of filling the drive to the brim.
ZZZ minimum system requirements (PC, Android, iOS)
Good news for weak machines: ZZZ's minimum requirements are light for a modern title. You don't need a new graphics card or huge amounts of RAM to get started.
| Device | Minimum requirements |
| PC | Windows 10 64-bit, Intel Core i5 7th gen, GTX 970, 8 GB RAM, DirectX 11.1 |
| Android | Android 11+, Snapdragon 855 / Dimensity 1200 / Kirin 990, 8 GB RAM |
| iOS | iPhone XS or newer, or iPad with A12 chip, 4 GB RAM, iOS 14 |
For smoother play, the recommended PC spec is a 10th-gen i7 with a GTX 1660; on phones, a Snapdragon 888 / Dimensity 8200 / Kirin 9000.
How to run ZZZ smoothly on a low-end machine
If your machine only meets the minimum, open the in-game Graphics settings and follow these steps for a smoother run:
- Start from the Low preset, then raise individual options only if your machine has room to spare.
- Lower Render Resolution below 100% — this is the single most demanding option, and dropping it visibly boosts FPS.
- Set Shadows and Effects to Low; the game still looks good while running far lighter.
- Cap FPS at 60 (or 30 on very weak devices) for stability, so the machine isn't fighting to push more than it can.
- Turn down Reflections and Anti-aliasing if your frame rate still dips.
On phones, use the battery-saver/low-performance mode and close background apps before launching.

Tips to save storage when installing ZZZ
A few ways to ease the load on your drive without hurting gameplay:
- Download only the voice pack you actually use (e.g. Japanese or English) instead of all of them — the PC size gap (57 to 71 GB) is mostly voice data.
- Install on the drive with the most free space, and on PC make sure you have at least ~115 GB free during installation before you start.
- Clear the recycle bin / temp files beforehand to avoid running out of room mid-download.
- Prefer an SSD if you have one: not required, but loading screens and scene transitions are faster and smoother than on an old HDD.
Can your device run ZZZ? Quick check
Quickly check these three things before downloading — if you meet all three, you can play:
- Free space: PC at least ~115 GB, Android ~20 GB, iPhone/iPad ~26 GB.
- RAM: 8 GB for PC and Android, 4 GB for iPhone/iPad.
- Hardware age: a GTX 970 or newer on PC; a mid-to-high phone from roughly 2019 onward (Snapdragon 855, iPhone XS, etc.).
If your device is below the minimum you can still try, but expect stutter — lowering the graphics as shown above is your best fix.
FAQ
Can I play ZZZ on a weak phone?
Yes, if it meets the minimum: Android needs a Snapdragon 855 / Dimensity 1200 / Kirin 990 with 8 GB RAM, and iPhone needs an XS or newer with 4 GB RAM. Older phones may launch but will stutter, so use the low-performance mode and close background apps.
How much free space do I need to install ZZZ on PC?
The download is only about 57 GB, but installing needs up to 110–115 GB of free space because the files are unpacked first and then compacted. After installation the game takes only about 57–71 GB, and the extra space is freed back up.
Do I need an SSD to play ZZZ?
No — a regular HDD works fine. But an SSD loads scenes and transitions faster with less hitching, so install on an SSD if you have the choice.
