Aspect Ratio
The proportional relationship between an image's width and height.
Aspect ratio is the proportional relationship between an image's width and height, expressed as two numbers separated by a colon (like 16:9 or 1:1). Different platforms prefer different aspect ratios—Instagram feed posts work best at 1:1 (square), Stories at 9:16 (vertical), and OG images at 1.91:1 (landscape). Understanding aspect ratios ensures your images display correctly across platforms.
