How to use this calculator
What to enter
Enter or select the following as requested: Horizontal pixels; Vertical pixels; Diagonal size (inches). Follow the units, valid ranges, examples, and options displayed beside each field.
What the result means
Pixel density or print resolution expresses how many pixels or dots fit into a physical inch or other displayed unit. Check whether the tool uses image pixels, print dots, or display pixels, and whether the dimensions are physical or digital.
When to use it
Use this to plan image size, print resolution, or display density. Confirm the target print size or display dimensions because the same pixel count can produce different physical resolution.
