Upload a 1000 × 1000 px square — Bluesky displays avatars in a circle at small sizes throughout the app.
Last verified June 2026
Bluesky avatars are squares displayed in a circular crop, rendered small beside every post, like, and reply in a fast-scrolling timeline. Bluesky doesn’t publish an exact required dimension; 1000 × 1000 px is the commonly recommended upload — large enough to stay sharp on every screen, small enough to sit comfortably under the platform’s ~1 MB file pipeline. On a network where many accounts still wear the default butterfly placeholder, a deliberate avatar does real work.

The circular mask removes the corners, and timeline renderings run small — roughly 40 px next to posts. Center the subject with about 15% padding on every side, maximize contrast against both light and dark backgrounds (Bluesky users split heavily between modes), and simplify until the mark reads at thumbnail size. Wordmarks and detailed illustrations lose to bold monograms and clear faces every time.
Bluesky timelines are dense with text, which makes the avatar the strongest recognition signal you have — people learn to spot your circle before they read your handle. Use the same mark you use elsewhere, set it on a distinctive solid color, and don’t rotate seasonal variants until the base version has had months to imprint.
Bluesky’s standout profile feature is the domain handle (@yourbrand.com), which doubles as verification. An avatar and a domain handle together read as “official account” at a glance — worth setting up before you invest in growth, because both appear beside every post you’ll ever write there.
Preview the avatar at 40 px on both white and near-black backgrounds before committing. Dark-heavy photos vanish in dark mode; pure-white backgrounds glow harshly. A mid-tone or brand-color field with a high-contrast subject survives both — and that tiny timeline rendering is where 95% of impressions happen.
Upload a sharp 1:1 square — 1000 × 1000 px is the commonly recommended size. Bluesky publishes no exact requirement; anything from 400 × 400 up renders cleanly in the circular crop.
Most likely the upload was small or pre-compressed. Re-export a clean square at 1000 × 1000 px under 1 MB; Bluesky’s downscaling is gentle when the source is sharp.
Yes — the official app displays avatars circular everywhere, so the corners of your square never show. Center the subject and leave padding so the mask doesn’t clip it.
