Xbox and PC game file sizes: the biggest games in August 2026 and what fits on your drive

How game file sizes are measured on this page

A game file size is the space the installed package occupies on the console's drive, and it is the only number that decides whether the next download fits. Stores show it before you buy; consoles show it in storage settings after you install; the two rarely agree to the gigabyte. This database records the store figure, because it is the one available before the download starts, and stamps every entry with the date it was read. Xbox Series X and PC sizes come from the Microsoft Store catalogue and Steam. PlayStation sizes come from PlayStation Store data. When a figure cannot be confirmed from one of those sources the cell stays empty rather than guessing.

Three things make the numbers move. Patches fold into the base package and grow it a few gigabytes at a time. Language packs and high-resolution texture packs are sometimes optional and sometimes not, which is why the same game can be listed at 60 GB on one store and 90 GB on another. And publishers occasionally re-master the package: Call of Duty titles have shrunk and grown by tens of gigabytes between seasons as assets were split into separately downloadable modules.

PS5 game file sizes: why Sony's consoles install smaller

PS5 game file sizes run smaller than their Xbox and PC counterparts, and the biggest PS5 games still clear 100 GB. The PS5 ships with a hardware Kraken decompressor that unpacks assets on the fly, which lets developers keep more of the package compressed on disk. The practical effect is visible across the table above: for most multiplatform releases the PS5 build is the smallest of the current-generation versions, often by 10 to 25 percent. A second factor is Sony's approach to optional content. PS5 titles more often let you skip single-player or multiplayer modules, and the store figure reflects the default selection.

The launch PS5 has an 825 GB drive with about 667 GB usable after the system reserve; the Slim and Pro models ship with 1 TB and about 848 GB usable. The stacked meter above shows what installs of that class do to a drive in practice. Five of the biggest games fill the launch console, and that is before a single patch. An M.2 expansion drive is the standard answer, and the PS5 SSD checker lists which drives meet Sony's speed and height requirements.

Xbox game file sizes: Series X, Series S and Smart Delivery

Xbox game file sizes tend to be the largest of the three console platforms. Part of that is packaging: many Series X|S downloads carry both the Series X and Series S asset sets, and the console keeps what it needs. Part of it is compression, which is applied per-package by the developer rather than across the board by the hardware. The upside is that Xbox is the most transparent platform about size: the Microsoft Store catalogue exposes the exact package size in bytes, which is where the figures in the table come from, and Smart Delivery keeps a single listing for Xbox One and Series versions.

The Series S is the platform where size hurts most. Its 512 GB drive leaves about 364 GB usable, so three or four of the biggest games fill it. The Series S build of a game is typically 20 to 40 percent smaller than the Series X build because it ships lower-resolution textures, and the table lists the Series X|S package as the store reports it.

Switch, Switch 2 and PC

Switch game file sizes are small because the assets are: a game that needs 80 GB on PS5 can fit in 15 GB on Switch with lower-resolution textures and compressed audio. Switch 2 changes that. Native Switch 2 games and Switch 2 Editions ship larger assets, and the console's 256 GB of storage (about 221 GB usable) fills quickly; game-key cards, which download the full game rather than storing it on the card, make the microSD Express slot a near-necessity for physical buyers.

PC game file sizes are the least predictable because the platform allows the most choice. Steam lists a required space that reflects the default install; 4K texture packs, uncompressed audio options and language packs can push the real figure far beyond it. The PC column uses Steam's listed requirement and notes on the game pages where an optional pack changes the total.

Why game file sizes are so big now, and where the trend goes

The biggest Xbox games in the database are open-world and live-service titles, and the direction is one way: the average install size of a new AAA release has roughly doubled since 2019. The largest entries now sit well above 150 GB, and the first titles to announce sizes above 200 GB for their full content have already arrived. At the other end, remasters of PS3-era games and most indie releases still fit in single digits.

Two developments push back against the growth. Compression improvements on PS5 and the Series consoles have kept some sequels flat despite larger worlds, and modular downloads let players skip the campaign or the multiplayer mode they do not use. Neither reverses the trend, but they make the storage planner worth using before a purchase rather than after the "not enough free space" message.

How to check game file sizes on each platform

Every store shows the install size before purchase, but each hides it in a different place. On PS5 and PS4, open the game's store page and look under the platform badge for "File size"; on the console itself, Settings > Storage lists every installed title with its current footprint. On Xbox Series X|S and Xbox One, the store page lists "Approximate size", and Settings > System > Storage shows the installed figure per game. On Switch and Switch 2, the eShop page states "Required space" for both the download and the physical version's mandatory download. On PC, the Steam store page lists storage under system requirements, and the Steam library's Properties dialog shows the real installed size after download; Windows 10 and 11 also list it under Apps > Installed apps. The database here collects those figures so you do not have to open four stores to compare one game.

Using the database

Each game has its own page with every platform's size side by side, a fit check against the common drive capacities, and links to the coverage of that game elsewhere on the site. The storage planner takes any selection of games and a drive and reports used and free space using the real usable capacity. Platform hubs for PlayStation, Xbox, Nintendo and PC list the sizes relevant to each console alongside the news and guides for it.
