About Aspect Ratio
Aspect ratio is the proportional relationship between an image's width and height. It's commonly expressed as two numbers separated by a colon (e.g., 16:9) or as a decimal (e.g., 1.78:1).
Common Aspect Ratios
- 16:9 - Standard widescreen TV, YouTube videos
- 4:3 - Traditional TV and computer monitors
- 1:1 - Square format, Instagram posts
- 9:16 - Vertical video, mobile screens, stories
- 21:9 - Ultrawide monitors, cinematic format
Use Cases
- Resizing images while maintaining proportions
- Designing responsive layouts for websites
- Video production and editing
- Print design and photography
- UI/UX design for different screen sizes
When resizing images, always ensure you're using the correct aspect ratio to avoid distortion. Maintaining the original aspect ratio is crucial for professional-looking results.
