Calculate and simplify aspect ratios for images, videos, and screens
Use this calculator to determine aspect ratios for images, videos, and screen resolutions.
Our Aspect Ratio Calculator helps you maintain perfect proportions across all your designs and media projects.
Aspect ratios define the relationship between width and height in visual media. Getting them right ensures:
Maintain 16:9 for YouTube or 9:16 for TikTok
Calculate responsive container proportions
Plan compositions with 3:2 or 4:5 ratios
When designing for multiple platforms, calculate your base aspect ratio first, then derive all other needed ratios from it.
