What is a 4:5 aspect ratio?
The 4:5 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-oriented of the landscape 5:4 aspect ratio previously found on older televisions.
The 4:5 ratio is 25% taller than the 1:1 square aspect ratio and 46.66% shorter than the 9:16 tall aspect ratio.
The aspect ratio has a standard format of 4:5 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.
4:5 ratio formula
You can use the four-by-five ratio formula to check if an image or display has a 4:5 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 0.8, then it has a 4:5 aspect ratio.

FAQs
How do I calculate the 4:5 aspect ratio?
The 5:4 aspect ratio is a screen or image format that proportionally contains four units horizontally for every five vertically. It can be calculated by dividing the width by height and getting a value of 0.8.
For example, the ratio between the width and height of the SXGA (1,280 x 1,024) and QSXGA (2,560 x 2,0248) resolutions equals 0.8.
How to use 4:5 aspect ratio calculator by Calculator Hub?
Our 4:5 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 4:5 aspect ratio. For instance, if you enter a width of 800 pixels, the calculator will calculate a height of 1,000 pixels.
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.
