What is a Pixel Aspect Ratio?

A Pixel Aspect Ratio (PAR) is a measure of the width to height ratio of a single pixel in a digital image. It is used to ensure that images are displayed correctly on different devices and screens. The PAR is calculated by dividing the display aspect ratio (DAR) by the storage aspect ratio (SAR).

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ PAR = \frac{16}{9} = 1.78 \]

The Pixel Aspect Ratio is 1.78.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ PAR = \frac{4}{3} = 1.33 \]

The Pixel Aspect Ratio is 1.33.
