How many GB is Hollow Knight?

9 GB

That makes it bigger than 89% of Platform games we have measured.

The median Platform game needs 1 GB; the largest tenth start at 10 GB.

Leave at least 16 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

A 2D metroidvania with an emphasis on close combat and exploration in which the player enters the once-prosperous now-bleak insect kingdom of Hallownest, travels through its various districts, meets friendly inhabitants, fights hostile ones and uncovers the kingdom's history while improving their combat abilities and movement arsenal by fighting bosses and accessing out-of-the-way areas.
