Finding Image Ratio for a stack
We have a great little ratio tool you can use below to help you with this. Just enter the height and width in W1 and H1 and your ratio will show below.
Instructions: Enter the values for the original width (W1) & original height (H1) on the left, then enter either a new width (W2) or new height (H2) on the right to calculate the remaining value.
Change any of the values at any time, or reset them to the starting values.
Your aspect ratio is: 4 : 3
