## How does this aspect ratio calculator work?

This is a tech online tool that you can use to determine the unknown value for a particular aspect ratio and can be used for instance to resize photos or video. The aspect ratio calculator requires you to input the original width value and the original height of what you want to resize, then one of the desired width OR height value you want, then you can find the other value to ensure a proper aspect ratio.

If the user wants to compute the New Width they need to input the other 3 values (Original Width, Original Height, New Height) then the calculator will use the following formula:

New Width = (Original Width * New Height)/Original Height

If the user wants to compute the New Height they need to input the other 3 values (Original Width, Original Height, New Width) and the below formula will be applied:

New Height= (Original Height * New Width)/Original Width

## Example calculations:

• Figure out the new height:

Original dimensions: 500x960

New width: 800

Result: the new height will be: 416.6667 (Whole number=417)

Aspect ratio for the original specified width and height is 48:25

• Discovering the new width:

Original dimensions: 234x786

New height: 120

Result: the new width will be: 403.0769 (Whole number=403)

Aspect ratio for the original specified width and height is 131:39
