Understanding Image Aspect Ratios: A Complete Guide
Image aspect ratio is the proportional relationship between an image's width and height, expressed as width:height (e.g., 3:2). It determines the shape of your image regardless of its actual dimensions.
Common Aspect Ratios:
- Square (1:1): Equal width and height
- Portrait (2:3): Height is 1.5 times the width
- Landscape (3:2): Width is 1.5 times the height

Best Practices for Image Cropping:
- Manual Cropping Options:
- Use built-in image editors for predefined ratios
- External editors for custom ratios
- Crop the shorter side based on the longer side
- Avoid enlarging images to prevent blur
- Website Considerations:
- Banner images: Follow formatting guidelines for responsive display
- Product images: Maintain consistent ratios for uniform appearance
- Gallery images: Enable crop settings for consistent display
Video Aspect Ratios:
- Uploaded videos display in 16:9 format
- Embedded videos follow source thumbnail ratio
- Background videos crop to fill available space

For calculating custom ratios, divide height by width and multiply by 100. Example: 2:3 ratio = (3 ÷ 2) × 100 = 150%.
