How much data or mb is required to install a unity editor

I’m trying to install a unity editor onto my laptop and i have no idea how much data is required to install it and i do not have much data to spare. I already have the unity hub installed.

It depends on which versions and how many addons like visual studio, Windows, Linux, mac build supports etc. (these are necessary if you plan to release the game in those platforms). I’m not too sure about just the base editor but it should be at least a couple gigabytes. I checked my editors and this was what I got but don’t take this as exact.

My 2020.3.24 editor is 25.4 gb but I remember adding a lot of addons

My 2021.3.1 editor is 8.88 gb with windows,mac, linux build support and WebGL

My 2021.3.2 editor is 8.9 gb with windows,mac, linux build support and webgl
