Forza Horizon 6's install size has been revealed ahead of next month's launch, and the figures are substantial. The Xbox mobile app lists the game at approximately 144GB on Xbox Series X|S and around 156GB on PC.
The title's launch window is already set: early access via the Premium Edition begins on 15 May, while the Standard Edition and Xbox Game Pass access follow on 19 May. The app listing that revealed the file sizes was reported by Pure Xbox.
Owners planning to install the game will need to free significant SSD capacity before download. The larger PC footprint likely reflects higher-resolution assets and platform-specific files; final requirements may still change once day-one patches and post-launch updates are applied.
Those preparing for Forza Horizon 6 should check available storage and account for additional space for future updates and DLC, particularly on consoles with limited SSD capacity.
