Why Aspect Ratio Matters for Visibility and Engagement
Instagram rewards correctly formatted content with better reach and retention. The aspect ratio—the proportional relationship of width to height in images and videos—affects both aesthetics and post performance.
Key Benefits of Correct Ratios
- Better screen real estate usage: Taller formats can dominate vertical space and hold viewers’ attention longer.
- Avoid cropping issues: Exact ratios prevent unintended cuts to important elements.
- Sharper image quality: Proper dimensions optimize pixel density across devices.
Choosing the correct aspect ratio is a foundational step towards higher engagement and brand impact.
