Is it possible to see the size of the download from the App store when updating an iOS device?

As some users have a limited amount of online data they can use in contracts, It would be useful to know the size of the download. Currently the only way I can find out is if the update is larger than 20mb. This then tells me I have to update over a WiFi network.

The size is normally the size of the full Application. What I do is I open the application info screen and look at the file size. Remember, App Store updates are full versions of the file being downloaded, and the existing one replaced.

There is unfortunately now why to do this quickly, you have to check each application individually from the update screen by tapping on it's icon.

As pointed out by @cksum, when finding the App on the iPhone, scroll to the bottom and it will show the size.

@gentmatt Thanks for the edit and updated screenshots. I am at work and my Mac is unusable today. – Diago Mar 19 '12 at 9:38
@cksum Bleh. It's due to the lack of auto-complete in answer :P – Diago Mar 19 '12 at 9:39
@Diago No problem. – gentmatt Mar 19 '12 at 9:42
Thanks for the help, I did not know that the whole app was downloaded again. – Graeme Hutchison Mar 20 '12 at 8:14

If got exactly what you need! If you jailbreak your device, there is an app called AppStore Update Size from the BigBoss repository, it's free and it looks like this:

You don't need to jailbreak to get that info. Simply search the App Store and find your program. Then scroll all the way down to the bottom. It shows that particular info: img.ly/images/3684277/full – cksum Mar 19 '12 at 9:11
I think that's the size of the app, not of the update. No? – Michiel Mar 19 '12 at 9:13
Same thing. Delta updates don't exist. When you update the app, iOS pulls the entire version and simply trashes the old one. And since that info always reflects the latest version, it will always apply to your update (should the developer change something that inflates the size, like Chaos Rings adding another language). – cksum Mar 19 '12 at 9:15
I see... Thanks for the additional information. With your permission, I would like to edit my answer with your information? – Michiel Mar 19 '12 at 9:18
@chsum Hope you don't mind that I stole your screenshot for my answer. – Diago Mar 19 '12 at 9:19
