How large is the download for unity 5.5?

I recently got a router with 20 gigs of data a month. (its the best thing offered where I live) I would like to download unity but I fear downloading it will use half or more of my monthly allotment in just a single day! So I need to know how large the download for unity will be.

You can download the installer, which is small (700kb), and then you can see the download size of individual components before you actual download. The total download size will depend on how many components you select. Note that MS Visual Studio will have a much larger download size than what is listed in the description.
