How It Works

Aspect ratio is the proportional relationship between width and height. Most cameras shoot 3:2 (like 35mm film) or 4:3. When cropping for social media (1:1 for Instagram, 4:5 for portraits, 9:16 for stories) or prints (5:4 for 8x10, 5:7 for 5x7), you lose pixels. Shooting with your target crop in mind helps you compose better and preserve resolution.
