Monitor DPI/PPI Calculator
Change the following values to represent your setupStephen Johnson / Copyrightimage.com
I like using View → Print Size in Photoshop because it lets me see an image at the exact size it will be printed. That makes it easy to judge how the final piece will look in the real world. For example, you can hold a picture frame up to your monitor to see how the print will sit inside it, or check whether the image quality will hold up under close inspection—especially useful if you’re producing something large, like a 10-metre print.
By default, Photoshop assumes a monitor resolution of 72 DPI. That was roughly correct for mid-1990s displays, but it’s not accurate for modern screens. If you know your screen’s physical size and the resolution it’s running at, you can calculate the correct DPI for your setup. Enter that value in Preferences → Units & Rulers to ensure Print Size displays your work at a true, real-world scale.
