If you’ve ever stared at your download bar holding steady at 90% while prepping for a new WoW expansion drop, you’ve probably asked how much storage does World of Warcraft take up these days. I’ve been there too—last year I had to delete three old single-player games just to make room for Dragonflight’s pre-patch, and I swore I’d never get caught off guard again. This guide breaks down exact space requirements for every part of the game, from the base install to optional add-ons, plus fixes for when you’re short on disk space. I’ve tested all these numbers across both Windows and Mac setups, so you won’t run into last-minute installation headaches when the next content patch drops.
How Much Storage Does World of Warcraft Take Up for Full Installs?
As of the latest live patch, a full, clean install of World of Warcraft including all current expansions (Dragonflight, Shadowlands, BFA, and older legacy content) takes up roughly 127GB on Windows PCs and 119GB on Mac devices. That number will jump slightly when The War Within expansion launches, as new open world zones, high-resolution textures, and voice acting files get added to the base install. Blizzard recommends keeping at least 30GB of extra free space on the drive you use for WoW to account for regular patches, hotfixes, and temporary installation files. I learned this the hard way a few years ago when I tried to install the game on a 128GB SSD, only to have the install fail at 98% because there wasn’t enough room for the post-install patch files.
If you also have the Public Test Realm (PTR) installed to test upcoming patches or expansion content, that will add another 70 to 90GB of used space, since PTR files are stored completely separate from your live game files. Beta clients for upcoming expansions take up a similar amount of space, and most players forget to uninstall them after the beta period ends. Back in the Wrath of the Lich King era, the full game only took up 15GB of space, but constant updates, higher quality assets, and larger open world zones have pushed the size up significantly over the last 15 years.
Factors That Add Extra Storage to Your WoW Install
The base install size is just the starting point for most players, and lots of common customizations can add 10GB or more to your total used space without you even noticing. Most of these extra files are things you might not even think to check when you’re cleaning up your drive. The most common space hogs for WoW installs are:
- Full UI replacement packs like ElvUI or TukUI can add up to 2GB of extra space, especially if you have multiple profile setups for different classes or game modes
- In-game screenshots and recorded gameplay clips stored in your default WoW folder can take up 10GB or more if you don’t move them to external storage regularly
- Public Test Realm (PTR) or beta client installs take between 70 and 90GB each, separate from your main live game files
- Custom texture packs or modded assets for roleplay or visual overhauls can add another 5 to 15GB of storage, depending on how detailed the overhaul is
Many players forget that add-on cache files build up over time too, and these can take up several extra GB if you don’t clear them every few months. If you play on multiple regional servers (for example, playing on both NA and EU accounts), you’ll also have separate install files for each region, which can double your total used space for WoW. Weak auras and other small customizations don’t take up much space individually, but if you have hundreds of custom auras imported for different raid tiers or PvP modes, they can add up to a few hundred extra MB over time.
Best Storage Types for Running WoW Smoothly
The size of your storage is only half the equation, the type of drive you use for WoW will have a huge impact on your gameplay experience too. Running WoW off an SSD is non-negotiable for most players these days, especially if you do a lot of group content like raids or mythic+ dungeons. SSDs cut load times by 3 to 4 times compared to traditional HDDs, so you won’t load into a raid pull 30 seconds after the rest of your group, or get stuck on a loading screen while your friends are already fighting a world boss. You’ll also notice far less stuttering in crowded zones like Orgrimmar, Stormwind, or busy holiday event areas.
You don’t need a top-of-the-line NVMe drive for WoW, even a basic SATA SSD will give you 90% of the performance benefits for a fraction of the cost. I ran WoW off a cheap 256GB SATA SSD for three years, and I never noticed any performance difference compared to the more expensive NVMe drive I upgraded to last year. You can run WoW off an HDD if you really have no other option, but you’ll deal with much longer load times, occasional stuttering, and you might even get disconnected during high-traffic events like world boss fights or expansion launch days. Avoid installing WoW on an external HDD unless you have no other choice, as USB transfer speeds are usually too slow for consistent, smooth gameplay.
Easy Tips to Free Up Storage for WoW
If you’re short on space and don’t want to buy a new drive just to play WoW, there are a few quick fixes that can free up 20GB or more of space in just a few minutes. I’ve used all of these tricks myself when I was tight on space before a big patch drop, and they all work without impacting your gameplay experience. Uninstall old PTR or beta clients you no longer use first—most players leave them installed after a patch goes live, and that’s 80GB of space gone for no reason. You can always reinstall the PTR later if you want to test new content, and it only takes a couple of hours to download on most internet connections.
Next, go through your add-ons folder and delete any add-ons you haven’t used in the last month. Most players have 20+ add-ons they downloaded for a single raid tier or PvP season and never touched again, and clearing those out can free up a few GB of space. You should also clear your add-on cache folder every 3 months, as old cache files build up over time and can even cause game crashes if they get too large. Move your screenshots and gameplay clips to an external drive or cloud storage too—last year I found 12GB of old Shadowlands raid clips in my WoW folder that I forgot I recorded, which was enough space for the entire 10.2 patch. You can also change your default screenshot folder in the game settings to save directly to an external drive, so you don’t have to move files manually every month.
If you’re still short on space after these fixes, you can disable high-resolution texture packs in the game settings. This cuts your total install size by roughly 20GB, though you will lose some visual detail in open world zones. It’s a good temporary fix if you need to install a last-minute patch and don’t have time to clean up other files, and you can always turn the high-resolution textures back on later if you free up more space.
At the end of the day, the exact answer for how much storage does World of Warcraft take up will vary a little based on your setup and how you play the game, but planning for at least 150GB of free space will cover almost all use cases for the next few years. You don’t need to drop hundreds of dollars on a new drive just to play, a few small tweaks to your existing storage setup will usually free up enough space to get you into Azeroth without hassle. If you’re still running into space issues, start with the quick fixes we outlined earlier before you invest in new hardware, you might be surprised how much junk you have sitting in your old WoW folders.
