What is a 9:16 aspect ratio?
The 9:16 aspect ratio is a portrait ratio used for photos and videos commonly seen on social media platforms like Facebook[1] and Instagram[2]. It's also a portrait orientation of the most popular ratio for HDTV and computer monitors, the 16:9 aspect ratio.
The 9:16 ratio is 46.66% taller than the 4:5 tall aspect ratio and 77.8% taller than the 1:1 square aspect ratio.
The aspect ratio has a standard format of 9:16 or W:H, where W is the width and H is the height of an image, screen, or container. In digital space, the measurement unit is in pixels. You can pronounce it "four-by-five" or "four-to-five" aspect ratio.
9:16 ratio formula
You can use the six-by-sixteen ratio formula to check if an image or display has a 9:16 aspect ratio. First, you must determine the width and height of your image, video, or screen in centimeters, inches, or pixels. Then, divide the width by the height. If the answer is 0.5625, then it has a 9:16 aspect ratio.

FAQs
How do I calculate the 9:16 aspect ratio?
The 9:16 aspect ratio is a screen or image format that proportionally contains nine units horizontally for every sixteen vertically. It can be calculated by dividing the width by height and getting a value of 0.5625.
For example, the ratio between the width and height of the vertical HD (720 x 1280) and vertical FHD (1,080 x 1,920) resolutions equals 0.5625.
How do you use the 9:16 aspect ratio calculator by Calculator Hub?
Our 9:16 aspect ratio calculator is easy to use. You only need to input one dimension (width or height), and the calculator will automatically calculate the other dimension based on the 9:16 aspect ratio. For instance, if you enter a width of 720 pixels, the calculator will calculate a height of 1,280.
On top of that, by entering a screen diagonal, you will also get additional information, including the screen's width, height, pixel density, and more.
