Use the form below to calculate the missing value for a particular aspect ratio. This is useful, for example, when resizing photos or video.
W1 H1 |
= |
W2 H2 |
Your aspect ratio is: ? : ?
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
