Enter the display aspect ratio and the storage aspect ratio into the Pixel Aspect Ratio Calculator. The calculator will evaluate and display the Pixel Aspect Ratio. 

Pixel Aspect Ratio Formula

The following formula is used to calculate the Pixel Aspect Ratio. 

PAR = DAR/SAR

  • Where PAR is the Pixel Aspect Ratio ( )
  • DAR is the display aspect ratio 
  • SAR is the storage aspect ratio 

How to Calculate Pixel Aspect Ratio?

The following example problems outline how to calculate Pixel Aspect Ratio.

Example Problem #1:

  1. First, determine the display aspect ratio. 
    • The display aspect ratio is given as: 3.
  2. Next, determine the storage aspect ratio. 
    • The storage aspect ratio is provided as: 2.
  3. Finally, calculate the Pixel Aspect Ratio using the equation above: 

PAR = DAR/SAR

The values given above are inserted into the equation below and the solution is calculated:

PAR = 3/2 = 1.5 ( )


Example Problem #2: 

For this problem, the variables required are provided below:

display aspect ratio = 8

storage aspect ratio = 9

Test your knowledge using the equation and check your answer with the calculator above.

PAR = DAR/SAR = ?
