What is the best banner image size for Bluesky accounts?

The optimal banner image size for Bluesky accounts is 1500 × 500 pixels.

This 3:1 aspect ratio ensures your banner displays correctly across all devices without important elements being cropped out. While Bluesky can accommodate other sizes, this dimension provides the best experience on both mobile and desktop.

For best results when creating your Bluesky banner:

1. Keep important elements centered, as some edges may be cropped on certain devices

2. Test how your banner appears on multiple devices if possible

3. Use high-quality images that look sharp even when scaled down

4. Consider how text will appear - avoid small text that may become unreadable

5. Ensure good contrast between any text and the background

A well-designed banner helps establish your brand identity on Bluesky and makes your profile more visually appealing to potential followers. When designing your banner, remember that simplicity often works best - a clean, uncluttered design with your logo or a simple visual that represents your brand identity can be more effective than a complex image.
