Whenever you go into File - New to start a new project, choose an appropriate preset that you've saved, or set the pixel counts and ppi value manually.ĥ. Keep in mind you might want to do this for a number of different sized images and devices.Ĥ. Name it something appropriate like iPhone4 1' x 2'. Set it to the number of horizontal and vertical pixels you want to work with and the output device resolution (e.g., 326 ppi in this example) and before you hit OK, click the button. Choose File - New to create a new document. Enter that into the Print Resolution field for safe keeping.ģ. You might get a number like 326 ppi for an iPhone 4, for example. Figure out what the exact screen resolution on the mobile device is. Go into Photoshop's Edit - Preferences - Units & Rulers menu and enter that value into your Screen Resolution field for safe keeping.Ģ. Do this by measuring the display and dividing by the number of pixels. Figure out what your exact screen resolution is on your development system's monitor. (I realize the problems that will occur for, say an image of 24' by 36' that won't fit on any screen.but I'm talking about a mere 2 x 2 image.) I design cell phone graphics and I need my PS screen display to appear exactly the same size as the cell screen will be.ġ.

So then the question is how do I get my screen display to show the exact same size as what the print/output display will be. Yes, when my image is printed, it comes out at exactly the 2x2 dimensions I set up.
