How to Use Aspect Ratio Resizer
The Aspect Ratio Resizer calculates new image dimensions while preserving the original aspect ratio. Enter your original width and height, then specify either a new width or new height — the tool calculates the other dimension proportionally. Shows the aspect ratio in simplified form (e.g., 16:9) and the scale percentage. Perfect for resizing images for web, social media, or print without distortion. Works for any dimensions — photos, videos, design assets, or screen resolutions.
