9 Best Free Online PPI Calculator Websites

Here is a list of best free online PPI calculator websites. PPI or Pixel Per Inch is a value that specifies the number of pixels present on 1-inch area of a screen. It is an important parameter for screens as it affects screen sharpness. Screens with higher PPI are sharper than screens with lower PPI. Pixel Density or PPI of a screen depends mainly on two parameters namely screen resolution and diagonal screen length. To find out the PPI of any screen, users can try these online PPI calculator websites.

These websites come with a simple PPI calculator that quickly assesses the input screen parameters and derives the screen PPI. To perform the calculation, users just need to enter the screen resolution (horizontal and vertical resolution/ pixels) and diagonal screen length. Besides PPI, some of these websites can also calculate the Dot Pitch of screens. To help out new users, I have also included the steps of PPI calculation in the description of each website.

These websites also offer additional tools that may come in handy. Using additional tools, users can perform Stock calculations, Ratio calculations, Statistics calculations, and more. Go through the list to know more about these websites.
