Calculate Image & Video Scale
When resizing images or video, maintaining the correct Aspect Ratio is critical to prevent distortion. This tool calculates the ratio between width and height (e.g., 1920:1080 = 16:9) and helps you find new dimensions that fit perfectly within that scale.
Common Aspect Ratios Guide
| Ratio | Common Use | Resolution Examples |
|---|---|---|
| 16:9 | Standard HD Video (YouTube, TV) | 1920x1080, 1280x720, 3840x2160 (4K) |
| 4:3 | Standard Definition TV, Old Monitors | 1024x768, 800x600, 640x480 |
| 9:16 | Social Stories (TikTok, Instagram Reels) | 1080x1920, 720x1280 |
| 1:1 | Square (Instagram Feed) | 1080x1080, 500x500 |
How to use?
- Calculate Ratio: Enter your original Width and Height (e.g., 1920 x 1080) to see the aspect ratio (16:9).
- Resize: Enter a New Width (e.g., 500). The tool will automatically calculate the matching New Height to keep the image proportional.
