About this tool
Image Aspect Ratio Calculator
A browser-based image aspect ratio calculator that reads the source dimensions and returns the simplified ratio, helping you compare image proportions before resizing or cropping.
About Image Aspect Ratio
Aspect ratio describes the proportional relationship between an image width and height. Knowing the ratio helps prevent stretching and makes it easier to choose crop or resize dimensions for a destination layout.
How to use this tool
- Choose one or more images.
- Click Calculate Ratio.
- Review the pixel dimensions and simplified ratio.
- Use Image Cropper or Image Resizer when you need to adapt the image to another proportion.
Important notes
A ratio such as 16:9 describes proportions, not a fixed pixel size. Many different dimensions can share the same aspect ratio.
