Dimensional Ratio Guide: Understanding Image Proportions for Web Design
Dimensional ratios describe the proportional relationship between an image's width and height. They're expressed as a comparison formula (like 3:2) and determine the shape of your images regardless of their actual size.
Common Dimensional Ratio Examples:
- Square images: 1:1 ratio (500px × 500px or 1500px × 1500px)
- Portrait images: 2:3 ratio (500px × 750px or 1500px × 2250px)
- Landscape images: 3:2 ratio (750px × 500px or 1500px × 1000px)

- Custom Cropping:
- Crop the shorter side based on the longer side
- Avoid resizing the longer side to prevent blur
- Use a dimensional ratio calculator for precise measurements

Product Images:
- Maintain consistent ratios for uniform appearance

Calculating Percentage Ratios:
- 100% = Square images (1:1)
- Below 100% = Landscape orientation
- Above 100% = Portrait orientation
- Formula: (height ÷ width) × 100
