How to Format Images for Web Display: A Squarespace Guide
Images play a crucial role in web display, with several key factors affecting their appearance and performance. Here's what you need to know:
Key Display Factors:
- File size: Maximum 20MB (recommended under 500KB for faster loading)
- Optimal width: 2500 pixels for best quality across devices
- Minimum width: 1500 pixels to avoid blurriness
- Aspect ratio: Relationship between height and width
- Container fit: Images must match their container shape to minimize cropping
Responsive Design Features:
- Automatic creation of 7 image variations (100px to 2500px)
- Dynamic sizing based on visitor's device
- Responsive containers that adjust to screen size
Best Practices:
- Upload high-quality images at or above maximum display size
- Keep page sizes under 5MB for optimal loading
- Use PNG format for transparent backgrounds
- Maintain consistent aspect ratios in galleries
- Add text as overlays rather than embedding in images
- Include alt text for accessibility and SEO
Troubleshooting Common Issues:
- Blurry images: Ensure width is over 1500 pixels
- Cropping problems: Match aspect ratio to container
- Color shifts: Check color mode and profile settings
- Mobile display: Consider device-specific previews
- Resolution issues: Upload at recommended dimensions
Image File Requirements:
- Keep files under 20MB
- Use proper file formats (JPG, PNG, GIF)
- Maintain resolution under 120MP
- Follow color profile specifications
For optimal performance, always save original files locally and test display across different devices before finalizing implementation.
Mobile-Specific Considerations:
- Banner images may crop differently
- Gallery layouts may adjust
- Image scaling occurs automatically
- Text overlay positioning may shift
By following these guidelines, your images will display properly across all devices while maintaining optimal site performance.
