Why use an Aspect Ratio Calculator?
When resizing or upscaling images and videos, maintaining the original aspect ratio is crucial to avoid stretching or squishing the subject. Common aspect ratios include 16:9 (standard HD video), 4:3 (older TVs and iPads), 1:1 (Instagram squares), and 9:16 (TikTok and Reels).
