You can scale iOS simulator to desire scale (I tried from .2 to 1.4 ) and it worked for me.
To do this you have to go to /Library/Preferences and edit com.apple.iphonesimulator.plist >file. Edit value for KEY SimulatorWindowLastScale to desire scale.
I tried this on latest Version of Mountain Lion (10.8.4) and on the iOS 6.0 simulator.

I tested it on 10.8.x (with other Simulator Devices), but not on 10.9.x or 10.10
