Aspect ratio is a fundamental concept in visual media that defines the proportional relationship between the width and height of an image or screen. It is expressed as a ratio of the width to the height, determining the shape of the visual frame. Common aspect ratios include 4:3 (standard television), 16:9 (widescreen television), and 3:2 (traditional still photography).
The choice of aspect ratio has a profound impact on the composition and visual storytelling of an image or video. Different aspect ratios evoke distinct aesthetic qualities and serve specific purposes. For example, widescreen ratios are often used in filmmaking to create a more expansive and cinematic experience, while square ratios may be employed for artistic or social media purposes. Understanding aspect ratios is essential for visual storytellers and designers to effectively convey their intended message and engage their audience.
