You have to use the same sizes on retina and normal displays. For example, you have image view with size 100×100. On retina device you should use the same size 100×100 (no changes in your code). However you’d better use high-res image (2x size). For this you need to name it properly:
image.png – normal size image
[e-mail] – 2x size image.

When you call

UIImage* img = [UIImage imageNamed: @"image.png"];

image.png would be used on normal display and [e-mail] on retina (iOS does it automatically).
