Pixels Per Square Inch Calculator

Formula

The formula to calculate the pixels per square inch is:

\[ PPI = \frac{P}{A} \]

Where:

\( PPI \) is the pixels per square inch
\( P \) is the total number of pixels
\( A \) is the area in square inches

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:

Total Number of Pixels (P) = 2,073,600 (which is equivalent to a 1920x1080 resolution)
Area in Square Inches (A) = 50 square inches

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.
