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
Use the form at left to calculate the missing value for a particular aspect ratio. This is useful, for example, when resizing photos or video.
Say you have a photo that is 1600 x 1200 pixels, but your blog only has space for a photo 400 pixels wide. To find the new height of your photo—while preserving the aspect ratio—you would need to do the following calculation:
original height / original width x new width = new height
1200 / 1600 x 400 = 300
Note: this is the new, improved version. You can still use the original aspect ratio calculator if you prefer.
