Did you know? Image aspect ratios are crucial for social media! Instagram prefers 1:1 (square) or 4:5 (portrait), while YouTube thumbnails use 16:9. The Golden Ratio (1.618:1) has been used in art and photography for centuries because it's naturally pleasing to the human eye. Modern displays use 16:9 (widescreen) or 21:9 (ultra-wide) ratios.
