Do your final review of your graphic on your mobile device.Digital Ruler Online – Actual Size Measurements App Keep in mind your main display monitor is probably nowhere near as pixel-rich* as the mobile device you're targeting.ħ. If you want to preview it at the actual size it will show on the target device, press the button (you're equating printing with publication on your target device). You can do this, while the Zoom Tool is active in the Tools Panel, by pressing the button at the top of the Photoshop main window.Ħ. While working, examine your design at whatever zoom is comfortable to work at, but remember to look at it at 100% pixel size on the monitor (which will display larger than on the final device) to ensure all your effects are nice and clean. 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.

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.
