Size of windows phone 8.1 update

It told me 704.05mb, I did not have enough space so I am trying to uninstall apps and delete stuff....
 
less than 1 GB? good I have 3.5 GB free but it will take too long to download 21% now haaah I'm waiting
 
That's zipped size am sure it will unpack a little more. Current OS clocks at 2 GB so you have to account for files it will unpack once it completes installation. 700mb is just the file size of download.
