Aspect ratio formulaĪspect ratios are written out as a formula of width to height, such as 3:2. For an X:Y aspect ratio, the x is the image’s width and the y is the image’s height. While an image’s aspect ratio will help you understand its shape, it doesn’t determine the image’s actual size. What is an aspect ratio?įirst let’s cover the basics: An aspect ratio is how large an image’s width is compared to its height, without any pixels or units attached. So, here’s what designers need to know about aspect ratios and the user experience. However, as designers work more cross-collaboratively and design assets within websites or apps, it’s likely they’ll come across the term every so often or use it to communicate the component ratios that need to be locked. So if you drag your browser in to narrow the width, the video changes its size-adapting as you go.
For example, look at InVision’s homepage: You can see how that header video appears to be a 16:9 ratio, but it responds. In UX design, aspect ratios become somewhat antiquated because they’re inflexible and good digital design is responsive. Most often, they are used in describing film. Aspect ratios are commonly presented as two numbers, separated by a colon like X:Y, or 4:3. Simply put, an image’s aspect ratio is the relationship between its width and height. Screens, images, and frames all have recognizable shapes and aspect ratio is the term used to describe the fixed proportions of these shapes. Pull up YouTube, and it’s a widescreen rectangular shape at 16:9.

The most common is 16:9 see the table below for the most common ratios for each type of use.Ĭommon aspect ratios for different video uses Video Format
There are many aspect ratios used for various purposes in film and video, and some are more common than others. While images come in many shapes and sizes, there are some aspect ratios that are more commonly used for images and photography.Ĭommon aspect ratios for images and photography Aspect Ratio Thus, 4k scaled to 8k resolution is equal to 7680 x 4320. Multiply both parts of the resolution by 2 Then divide the number of rows and the number of columns by the greatest common factor.Įxample: let’s double the 4k 38 resolution to find the 8k resolution. To reduce a ratio, find the greatest common factor of both the number of columns and the number of rows.

Some video aspect ratios cannot be evenly reduced into these ratios, in which case they should be reduced to the number of columns to 1 row of pixels.Ĭinema projection screens often use a ratio of 2.35:1 or 2.4:1, for example. To find the video aspect ratio reduce the aspect ratio to either 16:9, 16:10, or 4:3. The aspect ratio is the ratio of the number of columns to the number of rows of pixels that make up a video display or image.Īn aspect ratio is often expressed as reduced to a common format based on industry standards. These squares or rectangles are called pixels. Screens display images as a grid of colored squares or rectangles in a grid, and the width and height of that grid is the resolution. An aspect ratio indicates the shape of a video screen or image.
