Aspect Ratio (n.) The proportional relationship between an image’s width and height, typically expressed as two numbers separated by a colon (e.g., 4:3, 16:9). In mobile photography, different aspect ratios are used for various purposes. For example, 4:3 is common for standard photos, 16:9 for widescreen displays, and 1:1 for square social media posts. Many smartphone cameras allow users to choose the aspect ratio before shooting, or crop to different ratios during editing.
