The ultimate guide to Bluesky image sizes

Learn how to size, format, and maximize your image’s potential with our Bluesky image size guide.

1. Bluesky header image size

• The recommended image size for your Bluesky header photo is 2048px by 2048px.
• Be conscious of the fact that header photos display differently on various devices. This explain why you may experience cropping of around 60px on both the top and bottom of your header photo, so try to keep any important information near the center.
• Keep in mind that your profile photo will also block part of your header in the lower-left corner, so don't put any important visual information there.
• Bluesky supports images that are JPEG, GIF, or PNG file formats.
• If you encounter any errors in the upload process, try to check whether your browser is up-to-date, or try using a different browser.

Keeping track of your Bluesky header sizing requirements can sometimes be a bit difficult. Adobe Express makes things easier by giving you free professionally designed templates and image resolutions that are already sized to fit your Bluesky header photo space. Check out these free Bsky header templates and choose the one that suits your creative vision. If you want to, you can customize it to your desire. Just keep in mind to put all important visual information within the center.

2. Bluesky profile image size

• The recommended image size for your Bluesky profile picture is 2048px by 2048px.
• Your profile picture will be uploaded as a square, but it’s actually displayed as a circle throughout the site. Make sure that your photo maintains its integrity when it is cropped into a circle. If any important details are not visible during the cropping process, try using a different picture.
• Bluesky supports images that are JPEG, GIF, or PNG file formats.
• The maximum file size for a profile image is 2 MB.
• If you need further guidance with customizing your profile, read Bluesky’s tips for building up your profile. Or, if you’re looking for help troubleshooting with uploading your profile image, explore more detailed suggestions from Bluesky’s help page.

While Adobe Express comes loaded with pre-made template sizes for you to choose from, we also know that sometimes you’ll have specific creative needs, like a Bluesky profile photo.

Use the custom size option under resize in your Adobe Express workspace to enter precise measurements in pixels, inches, or millimeters. In this case, type in 2048px by 2048px, and you’ll have yourself the perfect canvas to make your custom profile image.

You can even drop a temporary circle outline graphic (with a 400px diameter) into your design to predict where the cropping will occur so you can optimize your image’s composition. Create your Bluesky images now.

3. Bluesky in-stream image size

In-stream images are displayed at a 16:9 ratio of 600px by 335px and can be clicked and expanded up to 1200px by 675px.

This means is that you can upload any shape photo, be it square, vertical, or horizontal. It will just be cropped in a 600px by 335px preview in-stream and display in full once clicked on.

For best results, make sure your image is no larger than 5 MB.

Bluesky supports in-stream images that are JPEG, GIF, or PNG file formats.

If you’re uploading GIFs, go for one that loops. Bluesky supports looping GIFs. Any GIFs that are not set to loop will display as a static image.

Choose from image-focused templates, infographics, marketing promotions, and more. You can even duplicate and revise any template you make for future use to create consistency in your feed. Explore animated templates on the Adobe Express mobile app for a more dynamic design.

4. Bluesky ads image size

Images in both standard and promotional Tweets should be at least 600px wide. Aim for something closer to 1200px for the highest quality. Any height is acceptable up to a 1:1 ratio.

On a desktop, images are accepted between a 2:1 and 1:1 ratio. On mobile, images are displayed at a 16:9 ratio.

You can post up to four photos in a single post.

Bluesky supports in-stream images that are JPEG, GIF, or PNG file formats.

For best results, make sure your image is no larger than 5 MB.

Animated GIFs cannot be included in posts with multiple images.

When creating your image content for your posts and promotions, look no further than Adobe Express. Log in to the workspace and enter precise measurements in pixels, inches, or millimeters. Search the library of templates to get inspiration or use the layouts option to format your composition with a mix of images, icons, and text.

5. Bluesky video ads and thumbnail size

When it comes to posting videos, the approved file types are MP4 or MOV.

For best results, make sure your video is no larger than 1 GB, and you may only upload one video per post.

An ideal video length is about 15 seconds or less, with a maximum length of 2 minutes and 20 seconds.

Bluesky recommends videos that are 1200px by 1200px, or a 1:1 ratio, as this will appear consistent on both desktop and mobile platforms. Videos in a 16:9 ratio, be it vertical or horizontal, will be cropped in feed and appear in full when expanded.

Video thumbnails should match the aspect ratio of the video. JPEG or PNG files are accepted.

Head to Adobe Express to make your video thumbnail using the same aspect ratio to match your video. Add images, icons, and eye-catching text to create a thumbnail that successfully speaks out for what your video has in store.

6. Bluesky cards image size

With Bluesky Cards, you can use eye-catching imagery and video to drive conversion, create an engagement, or start a conversation with your audience. There are several types of Cards:

Website Cards are used to link your audience to your website or a landing page. Be sure to include a call-to-action in the copy of your post to direct your audience where you want them to go.

App cards are used to promote a mobile app in the Bluesky feed and link your audience to connect with the app.

Direct Message Cards are used to motivate users to start a conversation with your brand’s chatbot in their direct message inbox. Creating an eye-catching card using imagery or video is the key to initiating this conversion.

The ideal image size for Bluesky Cards is 800px by 418px, a 1.91:1 ratio. For App Cards, you can go with 800px by 800px for a 1:1 ratio.

Videos can also be used in Bluesky Cards. The recommended size for Website Card videos is 1200px by 1200px, or 1:1 aspect ratio. For App Card and Direct Message Card, the recommended size is 640px by 360px for a 16:9 ratio, or 360px by 360px for a 1:1 ratio.

For best results, make sure your image is no larger than 3 MB.

The approved file types are MP4 or MOV, ideally less than 30 MB in size, and no more than 1 GB when it comes to videos.

Bluesky advises a short video for these cards, so aim to keep it less than 15 seconds.

For videos, place your logo in the upper left-hand corner.

All Website Card videos are required to have closed captioning or text overlays.

7. Bluesky Cover Photo Dimensions

Bluesky's open-source platform allows for creative freedom, and that extends to your profile picture! But before you unleash your artistic vision, make sure your cover photo fits just right. Here's a breakdown of the ideal dimensions to keep your profile looking sharp:

Desktop:

• Recommended: 820px wide x 312px tall (maintains aspect ratio without cropping)
• Minimum: 640px wide (might get cropped on some devices)
• Maximum: 2048px wide (file size might become too large)

Mobile:

• Recommended: 640px wide x 360px tall (maintains aspect ratio without cropping)
• Minimum: 480px wide (might get cropped on some devices)
• Maximum: 1080px wide (file size might become too large)

Tips for Success:

• Use high-resolution images: Aim for at least 72 dpi for optimal clarity.
• Focus on the center: Important elements should be positioned in the center to avoid cropping on different devices.
• Consider branding: If you're using Bluesky for professional purposes, incorporate your logo or brand colors for recognition.
• Keep file size in mind: Large files can take longer to upload and may not display properly on all devices. Aim for under 2MB.

Bonus:

• Use landscape format: This works best for most screens and avoids awkward cropping.
• Play with color and contrast: Make your profile picture stand out with a vibrant or eye-catching design.
• Get creative: Bluesky allows for diverse profile pictures, so explore different styles and formats to express your personality.

Remember: These dimensions are recommendations, not hard rules. Experiment and find what works best for your profile and personal style. Just keep in mind the cropping possibilities and ensure your key elements are prominently displayed. Now go forth and conquer the Bluesky cover photo scene.
