What is the aspect ratio of a portrait photo or a video?
Let's start from the beginning - what is the aspect ratio? Aspect ratio is a relationship between the width and height of an image. We usually express aspect ratio with two numbers and a semicolon between them — for instance,
4:3. The concept is most prevalent in the film. However, understanding aspect ratios may come in handy for anyone who wants to fit their project's ratios in various mediums.
What about the aspect ratio of a portrait? Although there are no boundaries on how you can depict a portrait, you can always adopt certain video and photograph aspect ratios that are most common when taking portraits. Those aspect ratios are:
3:2, and the
4:5 (the latter two being standard photo ratios).
How do I calculate portrait aspect ratio?
To calculate portrait aspect ratios, in other words, to resize your files while maintaining portrait aspect ratio, you can use the following formula:
aspect ratio = width / height,
aspect ratio– The aspect ratio you're trying to adjust your file to;
width– Width of your file; and
height– Height of your file.
For instance, if you were trying to resize an image to fit a
3:2 (1.5) ratio, knowing it has a height of 500 px, you would multiply 500 px by
3/2 to get the width, which equals 750.
