What is Pixels Per Square Inch?

Pixels per square inch (PPI) is a measure of pixel density or resolution of a digital image or display. It indicates the number of individual pixels present in a one-inch square area of the display or image. Higher PPI values typically mean better image quality and sharper details, as more pixels are packed into the same area. PPI is an important metric in various fields such as digital photography, printing, and display manufacturing, as it directly affects the clarity and detail of the visual content.

Example Calculation

Let's assume the following values:

Using the formula to calculate the pixels per square inch:

\[ PPI = \frac{2,073,600}{50} = 41,472 \]

The pixels per square inch (PPI) is 41,472.
