SUMMARY: The official parallax resolutions are... iPhone 6: 872 x 1634 iPhone 6+: 2706 x 2706 Thanks to Doublemint for helping with the 6+ resolution! ORIGINAL POST: Now that we have a jailbreak for iOS 8, had a look at the default wallpapers on my iPhone 6 to get the dimensions for parallax. The default wallpapers are sized at 872 x 1634 px (see the default Milky Way wallpaper attached). I just thought I'd share for anyone else who wants to make parallax wallpapers for the new iPhone. I don't have a 6+. But, if someone who has a jailbroken 6+ wants to grab the default wallpapers to get the dimensions, I will be happy to update this post.
