What is Pixel Density?

Pixel density is defined as the total number of pixels per square inch of a screen. It can also be defined as the number of pixels per square mm or any other unit of length, but an inch is the most common.

Example Calculations

Example 1:

Using the formula:

\[ PD = 300 \times 300 = 90000 \text{ pixels per square inch} \]

Example 2:

Using the formula:

\[ PD = 400 \times 400 = 160000 \text{ pixels per square inch} \]
