Aspect Ratio

Aspect ratio refers to the proportional relationship between the width and height of a display or image, expressed as two numbers separated by a colon (e.g., 16:9). It describes the shape of the screen or picture, indicating whether it is more square-like or elongated. For example, a 16:9 aspect ratio is common for HDTVs and computer screens, offering a widescreen experience, while a 4:3 aspect ratio was standard for older televisions. Understanding aspect ratio helps ensure images and videos display correctly without stretching or cropping.
