Baldur's Gate 3 is a large install: Larian lists 150 GB of required storage, and it must be on a solid-state drive (SSD), not a hard drive. The size comes from the game's enormous amount of fully voiced dialogue (tens of thousands of lines and hundreds of hours of performance capture), high-resolution cinematics, three sprawling acts of hand-built environments, and detailed character/creature assets. Because so much cinematic and audio data streams in continuously, an SSD is a hard requirement rather than a suggestion, unlike many games where it is merely recommended. On PC you can verify the actual footprint in Steam or GOG under installed files. There is no meaningful way to reduce the install; there are no optional texture packs to strip out. Post-launch patches (including the large Patch 7 and Patch 8 updates) have added content and can nudge the size up, so keep some headroom beyond 150 GB for updates and save files. Console versions are comparable in size to the PC build.
