How much GB does Black ops 4 have?

For me, Black ops 4 has 180 GB and WW2 170 GB. And that's not the case with any of my friends. Does anyone know why? How much is it with you.

PS4

The installation requires about 55 GB of free space, such things can be nagoogled, you can find something instantly. It's much easier than asking here.

Unfortunately it is. Black ops 4 should actually be much smaller. Not 180 GB. But according to calculations, the game isn't that big after all. It just shows it, I don't know why.
