The ‘pixel density’ league table

by Jerry D on September 11, 2010

When Apple launched the iPhone 4 it proclaimed that the clarity of its Retina display was so high, your eye would be “unable to distinguish individual pixels.”

Apple’s marketing might be OTT, but there’s a valid point here. Screen size isn’t everything. Instead, Pixels Per Inch (PPI) or pixel density is a better indicator of a superior screen. Here’s our list of the best displays we’ve encountered so far on Big Phone Fight:

  1. Apple iPhone 4  (329.650* PPI)
  2. Samsung Wave  (282.713 PPI)
  3. Motorola Droid  (264.771 PPI)
  4. Motorola Droid 2  (264.771 PPI)
  5. Google Nexus One  (252.149 PPI)
  6. HTC Desire  (252.149 PPI)
  7. Droid Incredible  (252.149 PPI)
  8. Blackberry Bold 9700  (245.907 PPI)
  9. Sony Ericsson X10  (244.913 PPI)
  10. Samsung Galaxy S  (233.238 PPI)
  11. Nokia X6  (229.469 PPI)
  12. Nokia C6  (229.469 PPI)
  13. Motorola Droid X  (227.826 PPI)
  14. HTC Evo 4G  (216.966 PPI)
  15. Sony Ericsson Satio  (209.801 PPI)

To satisfy your inner geek, our Pixels Per Inch (PPI) scores are calculated as follows:

  • Diagonal resolution (D) = √ screen height (pixels)² + screen width (pixels)²
  • PPI = D / diagonal screen size (inches)

* Yes. We know Apple claims 326 PPI for its Retina display. But the math says otherwise.
