Bluesky Image Size Guide
All Bluesky image dimensions and specifications
Bluesky uses different image shapes by placement. Banner images (1500x500 at 3:1) appear across the top of your profile. Profile pictures or PFPs (400x400) should be square because they display as circles. Post images can use square, portrait, or wide crops, but important text should stay away from the edges.
| Size Type | Dimensions | Aspect Ratio |
|---|---|---|
| Post Image | 1000×1000 | 1:1 |
| Banner Image | 1500×500 | 3:1 |
| Profile Picture | 400×400 | 1:1 |
Best Practices for Bluesky Images
Optimize your Bluesky photos for engagement
For Bluesky banners, keep faces, logos, and text near the center because profile layouts can crop edges differently. For profile pictures, upload a centered square image so the circular crop does not cut off the subject. Use JPG for photos and PNG for logos or graphics with sharp text.
