Home > Aspect Ratio

Formula: 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

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.
