Enter the resolution width (pixels) and the resolution height (pixels) into the Calculator. The calculator will evaluate the Resolution To Aspect Ratio. 

Resolution To Aspect Ratio Formula

AR = RW / WH


  • AR is the Resolution To Aspect Ratio ()
  • RW is the resolution width (pixels)
  • RH is the resolution height (pixels)

To calculate Resolution To Aspect Ratio, divide the resolution width by the resolution height.

How to Calculate Resolution To Aspect Ratio?

The following steps outline how to calculate the Resolution To Aspect Ratio.

  1. First, determine the resolution width (pixels). 
  2. Next, determine the resolution height (pixels). 
  3. Next, gather the formula from above = AR = RW / WH.
  4. Finally, calculate the Resolution To Aspect Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

resolution width (pixels) = 400

resolution height (pixels) = 100
