Emulate real device screen dimensions with iOS emulator

Question

Is it possible with iOS emulator shipped with Xcode and iOS SDK to emulate on the computer the real dimensions of the device on screen independently of the current computer's DPI. What I wanna to achieve is to test on the screen of my computer if the buttons are big enough for the user's fingers !

Answer 1

iOS simulator has only 3 possible scales in Window > Scale - 100%, 75% and 50%. It doesn't go farther than that. But from what I see non-retina 75% isn't much bigger than iPad screen in reality. Retina is twice that big so it doesn't match. I don't have iPhone to check.
