Link embeds are share cards—posts are timeline photos
When a Bluesky post includes a URL, clients often show a wide ~1200×627 embed card. That card sells the click. Edge-hugging type and tiny captions fail after compression and in multi-column layouts.
Native timeline photos often sit near 1200×675 (16:9). Profile banners are a very wide 3000×1000 strip. Stretching one export into every slot is how soft, clipped cards happen on AT Protocol apps.
Your site’s Open Graph (or equivalent) tags usually feed the embed. Export a clear 1200×627 master, publish it on the destination page, then verify the live card in Bluesky. Expect cache lag when you swap art mid-campaign.
Avatars are circles. Do not force the profile picture into this wide slot. Prefer one subject, high contrast, and a short title that still reads at phone preview size.
Good vs weak crop
Same short banner strip—quiet lower-left for the avatar, subject in the open mid/right band.

How Bluesky link embeds pick the image
Most embeds follow Open Graph-style meta on the destination page. Cropping here only helps if the live URL serves that file to crawlers.
- Prefer one clear subject and one short title.
- Avoid dense paragraphs on the card itself.
- Re-check after you change the live page.
Link card vs post vs banner
Three artboards. The link card sells a URL. The post photo sits in the timeline. The banner brands the profile header.
- Bluesky post size — 1200 × 675
- Bluesky banner size — 3000 × 1000
- Open Graph image — 1200 × 630 cross-network
