I would like to download "RAGE HD" which the App Store says is "643 MB", but after clicking "BUY NOW" there is a message:

There is not enough space to download "RAGE HD". Please delete some photos or videos.

But my "About" screen says I have "898 MB" available. How much extra space should I need to be able to download this game?

    So what appears to be the case is that the size indicated on the App Store is the amount of data which will be required to transfer to the device, but once the package arrived and unpacks then more space will be required to accommodate the uncompressed data :) – Nippysaurus Nov 24 '10 at 12:33

    iOS might also prevent you from installing an application that will fill your drive by requiring a certain amount of free space on top of the app's required space. This would be to stop you completely filling the drive and then being unable to operate normally with email/sms/calls, saving notes, etc with a full drive. – drfrogsplat Nov 25 '10 at 0:46
  • same thing happened to me. I just restored because I jailbroke. – user6366 May 10 '11 at 0:26
  • @drfrogsplat That's exactly right! You should make that an answer. Also, keep in mind that almost all apps store data for themselves (content, highscores, whatever) which take up a bit of space, too. – msanford May 10 '11 at 15:51

You have to take into account that the exact number is an approximated value and that the device needs additional space to install the application. I’m guessing that although the application says it’s 643Mb, it really uses some more when it gets installed. You’re really pushing the limits of your iOS there :)

Due to the way items are synced to the iPod and iPhone, you need a bit more space than the size of the app. So although the app may only take up 643MB, you'll actually need more to sync it.

I don't know the answer to your question in general, but as far as RAGE HD goes (all numbers on my Mac):

Size shown in Finder: 779.7 MB
Size shown in iTunes (Library > Apps): 743.6 MB
Size needed to install on my iPad (Devices > my iPad > Apps): 1.18 GB

                                           I think that's your answer, there
