What is the PPI of 1920x1080 24 inch?

Understanding Pixels Per Inch (PPI) for a 1920x1080 24-inch Display

The Pixels Per Inch (PPI) metric is crucial in determining the sharpness and clarity of a display. It represents the density of pixels on a screen, affecting the detail and smoothness of the image. This explanation delves into calculating the PPI for a 24-inch display with a resolution of 1920x1080.

Calculating PPI

  1. First, understand that the resolution of 1920x1080 means the screen displays 1920 pixels horizontally and 1080 pixels vertically.
  2. To calculate PPI, we need the diagonal resolution in pixels. This is found using the Pythagorean theorem: sqrt(1920^2 + 1080^2).
  3. Performing the calculation gives a diagonal resolution of approximately 2203 pixels.
  4. Since the screen size is 24 inches diagonally, the PPI is calculated as the diagonal resolution divided by the diagonal size in inches: 2203 pixels / 24 inches.
  5. This calculation results in a PPI of approximately 91.79.

In summary, a 24-inch display with a resolution of 1920x1080 has a PPI of approximately 91.79. This PPI value indicates the density of pixels per inch on the display, which is a key factor in the visual quality of the screen. Higher PPI values generally lead to sharper and more detailed images, making the understanding of this metric essential for evaluating display quality.
