LinkedIn post size
1200 × 1200px
Aspect ratio
1:1
A 1200 × 1200 px square is the safe default for LinkedIn image posts; 1200 × 627 px (1.91:1) is the spec for link previews.

LinkedIn image posts come in three working shapes. Square (1200 × 1200 px) is the commonly recommended default — it displays consistently across desktop and mobile feeds. Portrait 1080 × 1350 px (4:5) takes more vertical feed space and has become standard for designed graphics. And link shares are a separate format entirely: LinkedIn pulls the page’s preview image and crops it toward 1200 × 627 px (1.91:1). Add document posts — LinkedIn’s swipeable PDF carousels — and you have the full toolkit for the feed.
| Variant | Dimensions | Ratio |
|---|---|---|
| Square (recommended) | 1200 × 1200 pxCommonly recommended default; displays consistently everywhere. | 1:1 |
| Portrait | 1080 × 1350 pxTallest shape that displays comfortably in the feed. | 4:5 |
| Link preview | 1200 × 627 pxPulled from the linked page’s metadata, minimum 200 px wide. | 1.91:1 |
| Document (carousel) page | 1080 × 1080 pxSquare PDF pages are the common choice; portrait A4 also works. | 1:1 |
LinkedIn’s feed column is fairly narrow and identical in spirit on desktop and mobile, so squares display fully; very tall images can be slightly trimmed or shown with a tap-to-expand in some views, which makes the center of a 4:5 graphic the only fully guaranteed region. Keep chart labels, small text, and key figures away from the outer 10% of the canvas. For link previews, assume an aggressive center crop to 1.91:1 — page titles baked into the top of an og:image routinely get sliced.
LinkedIn’s PDF carousels are the platform’s standout organic format — swipeable, dwell-time-friendly, and rewarded by the feed. Design square pages at 1080 × 1080 px, one point per page, cover page written like a headline. A 7-page document regularly outperforms the same content flattened into a single dense infographic.
Shared links render a small 1.91:1 card whose image comes from the target page’s metadata — you cannot reliably art-direct it from the composer. When the visual matters, upload the image natively and place the link in the post text or first comment. Native images render larger and consistently.
LinkedIn tolerates — and rewards — more text in images than other networks, but only if it is structured: a chart with a clear takeaway line, a framework diagram, a before/after table. Set the smallest text no smaller than ~28 px on a 1200 px canvas so it survives mobile. If you publish the same graphic across platforms, schedule the square master everywhere and let the caption carry the platform-specific framing — SocialKit lets you tailor the text per network on one scheduled post.
A 1200 × 1200 px square is the safe, commonly recommended default. Portrait 1080 × 1350 px (4:5) takes more feed space and works well for designed graphics; both display cleanly on desktop and mobile.
1200 × 627 px (1.91:1), sourced from the shared page’s metadata. If the preview crops badly, fix the og:image on the website — or upload the image natively and put the link in the text.
Square 1080 × 1080 px PDF pages are the common choice — they display large and swipe cleanly on mobile. Keep one idea per page and design the first page as a headline, not a cover photo.
