Somewhere around 110ppi is ideal for typical desktop use. That’s a 27″ 1440p screen or a 40″ 4k screen. You’re right to mention that viewing distance is a major factor in choosing pixel density.

## Which phone has highest PPI?

The highest resolution available in the smartphone market is the whopping 806 PPI of the Sony Xperia Z5 Premium, which packs a full 4K image (2160 x 3840 pixels) onto a 5.5” screen. There are several phones with 1440 x 2960 pixels or thereabouts on 5.5-6.0 inch screens, for upwards of 550 PPI.

## How do I figure out my screen resolution?

For example – if the screen size is 5.8 inches and screen resolution is 1138 X 680, then PPI can be calculated as –1138X 1138 + 680 X 680 = 1757444. Square root of 1757444 is 1325.69. Now, divide the number 5.8 i.e. 1325.69/5.8 = 228.5. Screen sizes and resolutions can vary on the same mobile platform.
