An inch is a measuring unit of length and is represented as in or ''. One inch is approximately equal to 96px or 96 pixels per inch PPI.

I like that you can measure with a ruler directly on the screen to find out DPI. My monitor appears to have 85 DPI. Very useful this information. Great app. Most commonly, screens have a DPI value of Here are resources for you to find, or calculate, the DPI of your device.
Take a measuring tape against your screen to determine the width of the red line below in inches. Then, use the chart beneath the red line to convert that number into DPI. PPI or pixels per inch, as the name implies, it is a measurement used to calculate how many pixels are there in 1 inch.
So if you see an image property that says it has PPI, this means that there are pixels inside every 1x1 inch of that image. For example, you want to print a 8" x 10" image and it has 72 pixels per inch PPI, others call it image resolution. Then, you want to print the same 8" x 10" image but this time it has pixels per inch. Which do you think looks blurry and which do you think looks pretty professional?
