What the Doom Eternal install size means in practice
The Xbox Series X|S version is the largest listed build of Doom Eternal at 90.2 GB. Store listings show the size of the installed package, not the download; the transfer itself is usually 10–30 % smaller because the package is compressed on the way and unpacked on the console. Patches are added on top of the listed figure, so a game that has been out for a year commonly sits a few gigabytes above the number on its store page.
Doom Eternal is developed by id Software and published by Bethesda Softworks. Genre: Shooter. Platforms: PC, PS4, PS5, Switch, Xbox One, Xbox Series X|S.
Against the rest of the database, Doom Eternal at 90.2 GB sits above the average install of 43.0 GB across 446 games; 67 of them are larger. Within its genre the average is 60.2 GB, which puts Doom Eternal on the heavy side for a shooter of its generation. On a launch PS5 with 667 GB usable it takes 14 percent of the free space; on a 2 TB expansion drive about 5 percent. Deleting it frees exactly the listed figure plus any patches installed since the store listing was checked, and the saves stay.
To check several games against one drive, the storage planner uses the same figures. For the drive itself, the PS5 SSD checker lists which M.2 drives meet Sony's requirements.
