Pixel Size Calculator

Formula

To calculate the pixel size:

$PS = \frac{DS}{DR} \cdot 25.4$

Where:

$PS$ is the pixel size (millimeters)
$DS$ is the diagonal size of the display (inches)
$DR$ is the diagonal resolution of the display (pixels)
25.4 is the conversion factor from inches to millimeters

Pixel Size Definition

Pixel size refers to the physical size of an individual pixel on a display. It is a measure of how large each pixel is, which affects the overall sharpness and clarity of the image on the screen. Smaller pixels typically result in a higher resolution and a clearer image, as there are more pixels packed into the same area.

Example Calculation

Let's assume the following values:

Diagonal Size of Display (DS) = 15 inches
Diagonal Resolution of Display (DR) = 1920 pixels

Using the formula:

$PS = \frac{15}{1920} \cdot 25.4 \approx 0.198$

The pixel size is approximately 0.198 mm.
