Image size required to cover the screen on all iPhone devices

Question

I want to put the image in the background. It should fill the entire screen density like the iPhone 4,5,6,6S and iPAD. I will support only a portrait.

What should I do?

• Do I have to make 1920X1080 (iPhone 6s Plus) and put it in the background and then set autoscaling to full screen.
• Should I make ImageName@2x with a size of 640X960 , ImageName-667h@2x 1334X750 iPhone 6, ImageName-736h@3x 1920X1080 iPhone 6Plus, ImageName-568h@2x 640X1136 for iPhone 5?

Answer 1

You should stick with the second option (also consider using an asset catalog for this purpose instead of a set of images) because:

• This will reduce the package size of the application .
• This will help to avoid image distortion caused by image resizing.
• This will reduce the rendering of the CPU (which is implied by re-scaling the image).

Hope this helps you make the right choice. Greetings.
