Size of background images for an iOS app

  • 772

I need to make backgrounds for an application in Swift, I have the measurements of the different sizes for each iPhone:

Device          Points    Pixels     Scale  Physical Pixels   Physical PPI  Size
iPhone 6  plus  736x414   2208x1242  3x     1920x1080         401           5.5"
iPhone 6        667x375   1334x750   2x     1334x750          326           4.7"
iPhone 5        568x320   1136x640   2x     1136x640          326           4.0"
iPhone 4        480x320   960x640    2x     960x640           326           3.5"
iPhone 3GS      480x320   480x320    1x     480x320           163           3.5"

I have two doubts:

  1. Should the size of my images be the size of the column Physical Pixels?
  2. What is the size for a background for the iPad and iPad Mini?

  1. Best Answer

    The resolution of the images must be the resolution that it says in the column Pixels. For all intents and purposes, that is the screen size, even if the actual pixels are different.

    This document (in English) has a very good explanation: iPhone 6 Screens Demystified .

    For the iPad, the pixel sizes are 768x1024 and 1536x2048 (non-retina and retina respectively). It doesn't matter if it's iPad or iPad Mini, in pixels they are the same.
