By what fits on your drive

The biggest games that fit a 20 GB drive, without a wall of tiny ones. Every game here installs in 15 to 20 GB on PC, so the biggest of them still fit a 20 GB drive without being padded out by tiny games you did not need this page for.

Common questions
What are the best games that fit a 20 GB drive?
105 well-reviewed games install in 15 to 20 GB, so the largest of them still fit a 20 GB drive or cap while being substantial games rather than tiny ones. The most-played is Subnautica at 20 GB. Sizes are read from each game's own Steam page and are the PC download; console versions differ.
Why do install sizes change?
A game's download grows with updates and shrinks when a publisher recompresses it, so the figure here is what Steam listed when we last checked, not a permanent number. It is also the base game: large story or texture packs are separate and not counted.
