How many GB is Idle Tower Defense?

1 GB

That is less than the typical Strategy game, which needs about 3 GB.

Leave at least 7 GB free: games need headroom to unpack updates.

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

Control a single tower to fight off hordes of enemies. No randomization. Choose from a variety of modules to create unique builds and upgrade modules and survive endless waves.
