Choosing the right dimensions for a full-screen hero image is crucial for optimal display and load time. Here's a detailed guide to help you set it up.
1. Recommended Dimensions
- Resolution: Aim for a minimum resolution of 1920x1080 pixels. This size ensures high-quality display on most desktop screens.
- Aspect Ratio: Maintain a 16:9 aspect ratio. This is standard for modern screens and avoids awkward cropping.
2. Image Optimization

3. Responsive Design Considerations
- Mobile Devices: Prepare a smaller version, around 800x600 pixels, for mobile screens to ensure quicker loading.
- Use of CSS Backgrounds: If using as a CSS background, set background-size: cover to maintain aspect ratio and fill the space across devices.
4. Uploading and Positioning in Webflow
- Upload Image: Drag and drop your hero image into the Webflow Designer.
- Set Section to 100vh: Use the height setting (100vh) to make the section full-screen on all devices.
- Positioning: Center the image using background-position: center center for an even distribution.
