Windows 10 Update size?

[hexacore]

hey guys, as the title says how much in size is the update file of Windows 10?
i am on a limited data plan and already reserved my copy on july 29.

For desktop, anywhere from 2-4Gb. For mobile, I'd guess less than a gig.

Most of the ISOs of Technical Preview are in the order of 3-3.7 GB.
So, I think that the final upgrade is also likely to be of a similar size !
