Aspect Ratio Calculator

Formula

The formula to calculate the aspect ratio is:

\[ AR = \frac{PL}{\text{GCD}} : \frac{PH}{\text{GCD}} \]

Where:

\( AR \) is the aspect ratio
\( PL \) is the pixels in the length (width)
\( PH \) is the pixels in the height
\( \text{GCD} \) is the greatest common denominator between \( PL \) and \( PH \)

What is Aspect Ratio?

An aspect ratio is defined as the ratio of pixels along the length to the number of pixels along the height of some screen. It describes the proportional relationship between the width and height of a display. The aspect ratio is important in various fields, such as photography, videography, and display manufacturing, to ensure the content fits well on the screen.

Example Calculation

Let's assume the following values:

Pixels in Length (PL): 1920
Pixels in Height (PH): 1080

Step 1: Calculate the Greatest Common Denominator (GCD):

\[ \text{GCD}(1920, 1080) = 120 \]

Step 2: Calculate the Aspect Ratio:

\[ AR = \frac{1920}{120} : \frac{1080}{120} = 16 : 9 \]

Therefore, the aspect ratio is 16:9.
