Image resolution

Image resolution is the amount of detail an image contains. The optimal resolution is different for screen and print. Resolution is measured in dots (pixels) per inch (abbreviated as DPI). Too low DPI and your image will appear fuzzy and pixelated.

  • The minimum recommended screen resolution is 72 DPI.
  • The minimum recommended print resolution is 300 DPI.

How do I check the resolution?

On a Mac, open your image in Preview and go to Tools > Adjust size. The resolution will appear in the window.

On a PC, right click on your image file and select Properties, then click on Details. The resolution will appear in the window. 

What do I do if my image resolution is too low?

If your image resolution is below the recommended standard, we recommend first checking with the photographer to see if an original, higher resolution version is available. If not, you'll have to find an alternate photo. In some instances University Communications + Marketing can upsample an image.
