Here’s a quick run-down of resolutions and what they’re called: But there are times when a lower resolution is better, like if you need a smaller file size for your video or if you’re multistreaming to several platforms at once. Using a higher resolution is almost always to your benefit - a higher resolution means a better-quality image. It doesn’t work the other way around, though, as the aspect ratio doesn’t affect your choice of resolution. For example, 1080 looks best in a 16:9 aspect ratio. Typically, the resolution of an image or video determines its aspect ratio. The width and the height of the digital image is always 16:9, but the number of pixels per square inch increases as your resolution gets higher. It’s worth noting that almost all digital screens use a 16:9 aspect ratio only the resolution changes. We usually use the height (the second number) when talking about resolution, so 720p would indicate an image has 720 horizontal pixels, and 4K would be an image with approximately 4,000 horizontal pixels (3,840 exactly). If we use two numbers to calculate resolution, why do you only see resolution written as one number, such as 1080p? 1080 refers to the number of horizontal pixels in the image, or the height. You get the resolution by multiplying width by height, and you get the aspect ratio by dividing width by height. The video aspect ratio and resolution are closely related. How is resolution related to aspect ratio? The more pixels you have per square inch, the higher the quality of your image. The higher your resolution, the more pixels you have per square inch. The resolution is the number of pixels that make up the image on the screen, usually measured in PPI (pixels per inch). Images are full of little squares, or pixels, placed side by side. Now that you know what a video aspect ratio is, you need to understand video resolution and how the two fit together. The 16:9 ratio has become the standard aspect ratio for flatscreen TVs and online video. Around that time, the 16:9 ratio, which is directly between 4:3 and widescreen 2.35, was born. Aside from widescreen films at cinemas, 4:3 was the standard until the 1980s, with the rise of digital video. 4:3 was used until around the 1950s, when the widescreen “cinemascope” aspect ratio (2.35) took over. The first aspect ratio ever used was developed with 35mm film and was the 4:3 aspect ratio. Quick history lesson in video formattingĪspect ratios go back to the beginning of film in the early twentieth century. The video aspect ratio is often determined by the device you’re viewing the image on. Ratios may also be written as decimals, so 4:3 would be 1.33. But an image 16 pixels by 9 pixels would be too small to see, so we use an image that’s 1920 pixels by 1080 pixels instead. Both the width and height are measured in pixels.Ī common ratio for online video is 16:9. The first number in the ratio is the width, and the second number is the height. The video aspect ratio is a ratio, like 1:1 or 1:2, that determines the size and quality of your video’s image. The video aspect ratio is important, but what is it? How is it related to video resolution, and which aspect ratios should you use for uploading videos online? In this guide, we’ll cover everything you need to know about aspect ratios for your online videos and live streams. And when viewers have countless video choices online today, you can’t afford to sacrifice quality, especially not for something as simple as the video aspect ratio. The video aspect ratio probably isn’t the first thing you think about when uploading your video online - but it should be! Getting the aspect ratio of your video right will bring the quality of your video’s image up to a high standard.
