Pixel Density Calculator

Formula

The formula to calculate the Pixel Density (PD) is:

\[ PD = PPIw \times PPIh \]

Where:

\(PD\) is the pixel density (pixels per square inch)
\(PPIw\) is the pixels per inch along the width
\(PPIh\) is the pixels per inch along the height

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:

Pixels per Inch along Width (PPIw): 300
Pixels per Inch along Height (PPIh): 300

Using the formula:

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

Example 2:

Pixels per Inch along Width (PPIw): 400
Pixels per Inch along Height (PPIh): 400

Using the formula:

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