Graphics Display Resolution

Resolution and size are different.

The size of your graphic refers to its dimensions (the width and height) whereas the resolution refers to dpi (dots per inch) or ppi (pixels per inch).

  • DPI refers to the number of printed dots contained within one inch of an image printed by a printer.
  • PPI refers to the number of pixels in a linear inch when displayed on an electronic image device like a computer, tablet or your phone.

IEEE standards for non-vector graphics are >300dpi for color and grayscale images, and >600dpi for black and white “line art.” In cases where graphics, such as digital photographs, are produced at a lower resolution, acceptable quality can be achieved by ensuring that column-wide graphics are at least 1050 pixels wide and page-wide graphics are 2150 pixels wide.
