What is the best image size for LinkedIn posts?
1200×1200 px (1:1 square) is the safest universal default. It displays without cropping on mobile and desktop, works across every post type, and requires no reformatting for cross-platform use. Both Hootsuite's social media image sizes guide and Sprout Social's image size reference recommend it as the starting point.
LinkedIn supports three aspect ratios for single-image posts: square (1:1), landscape (1.91:1), and portrait (4:5). The format you choose directly affects how much screen space your post claims — especially on mobile, where over 60% of LinkedIn sessions happen. A portrait image at 4:5 occupies roughly 70% more screen area than a landscape image at 1.91:1, according to Buffer's social media image size analysis.
One-number rule: 1200×1200 px when in doubt. Landscape for link shares, portrait for visual-first content.
LinkedIn single image post sizes
Square posts — 1200×1200 px (1:1)
The universal safe choice. Displays without cropping on any device, renders cleanly in reshares, and matches Instagram's native format for easy cross-posting. The 1200 px width ensures sharpness on retina screens. Use square when you need one image that works everywhere.
Landscape posts — 1200×628 px (1.91:1)
The default format for link previews and Open Graph images. When you share a URL, the preview renders at ~1.91:1 — an OG image at this ratio displays perfectly; anything else gets cropped.
The trade-off is mobile real estate. Landscape images occupy significantly less vertical space on a phone screen, so users scroll past them faster. Best for posts where text is the primary content and the image is secondary.
Portrait posts — 1080×1350 px (4:5)
Claims the most vertical space LinkedIn allows in the feed. On mobile, this format fills nearly the entire screen. Images taller than 4:5 (e.g., 9:16) get cropped or letterboxed and require a tap to view — that extra tap kills engagement. Stay at 4:5 or wider.
Best for infographics, step-by-step frameworks, quote graphics, and any visual where the information density justifies the screen space.
LinkedIn carousel post specs
LinkedIn carousels are uploaded as PDF files — each page becomes one slide. Recommended slide dimensions: 1080×1080 px (square) or 1080×1350 px (portrait). LinkedIn supports up to 300 pages per PDF, though 5–15 slides is typical.
- Max file size: 300 MB
- Export at: 150 DPI or higher for crisp text
- Portrait slides give more vertical space per slide for text and diagrams — better for text-heavy carousels
- Square slides are easier to cross-post to Instagram
The first slide is your cover — make it visually arresting with a swipe indicator or slide counter. The final slide should include a call to action. According to Hootsuite's image sizes guide, carousels with a clear CTA on the last slide receive measurably more engagement.
Upload your carousel as a single PDF rather than multiple images. PDF carousels display with swipe navigation and a slide counter, which encourages readers to swipe through all slides. Multi-image uploads show as a gallery grid instead — less engaging and harder to follow a narrative sequence.
LinkedIn video dimensions and specs
MP4 with H.264 is the most reliable format. Square video (1:1) tends to perform best — it balances mobile screen real estate with a natural viewing experience. Portrait (9:16) maximizes mobile space but looks awkward on desktop; landscape (16:9) is standard for professional video but occupies the least mobile feed space.
Captions are essential. The majority of LinkedIn video views happen with sound off — Sprout Social's data estimates upward of 80%. Use LinkedIn's auto-caption feature or upload an SRT file.
LinkedIn profile photo and banner size
Profile photo — 400×400 px (1:1)
Upload at the highest resolution available — LinkedIn stores the original and generates smaller versions as needed. The image is cropped to a circle on display, so keep your face centered and avoid important content near the edges (the circular crop removes the outer ~15–20% of the frame). Solid or blurred backgrounds render most cleanly at small sizes.
Background banner — 1584×396 px (4:1)
Keep critical elements — text, logos, focal points — centered both horizontally and vertically. The left and right edges may be cropped on narrower screens, and the bottom-left corner is always partially obscured by your profile photo. Leave the bottom-left quadrant free of important content. LinkedIn's Help Center specifies these dimensions, and most design tools include LinkedIn banner templates with crop-safe guidelines.
LinkedIn article and newsletter cover images
The recommended size for both articles and newsletters is 1200×644 px. This wide landscape format matches the Open Graph standard, so the same image works when shared on other platforms. The cover appears as a small card in the feed and a full-width hero on the article page — keep text large enough to read at card size and the composition simple enough to survive scaling. LinkedIn's image specifications page confirms these dimensions.
LinkedIn company page image sizes
Company pages use separate image specs from personal profiles. The company logo displays as a small square (not cropped to a circle) — ensure it's legible at 40×40 px. The cover image is an extremely wide format with very little vertical space; use it for branding or a tagline, nothing complex.
Image format and file size limits
- Supported formats: JPG, PNG, GIF (static only — no animated GIFs), WebP. Adobe Express's LinkedIn image resizer confirms the same list.
- Not supported: TIFF, BMP, SVG, HEIC
- Max image size: 10 MB per image; 300 MB for carousel PDFs
- Ideal range: 200 KB – 2 MB. Files above 3–4 MB trigger more aggressive compression.
- JPG vs PNG: JPG for photographs and gradients. PNG for graphics with sharp edges, text overlays, and flat colors.
- Color profiles: LinkedIn strips EXIF data, including color profiles. Design in sRGB to avoid color shifts on upload.
There is no way to avoid compression entirely. LinkedIn re-encodes all uploaded images. PNGs with sharp text, thin lines, or solid color blocks suffer the most visible quality loss. To minimize artifacts: upload at the recommended pixel dimensions (not larger), keep file sizes under 2–3 MB, and use JPG for photographs, PNG only for graphics that require crisp edges.
How to optimize images for LinkedIn
- Design at the exact recommended dimensions. Don't design at 2400×2400 and let LinkedIn downscale. Oversized images get scaled then compressed — two passes of quality loss instead of one.
- Add alt text to every image. Alt text improves accessibility, and there's growing evidence that LinkedIn's algorithm factors accessibility signals into distribution.
- Use consistent visual branding. Establish consistent colors, fonts, and layout templates so your posts are recognizable in the feed before anyone reads the text.
- Pair strong visuals with strong copy. The image stops the scroll; the text drives engagement. Lunatic AI's content calendar generates post ideas with suggested text — pair it with a design tool for visuals and you've covered both halves.
- Preview before publishing. Check LinkedIn's mobile preview specifically — what looks fine at desktop width may be cropped or tiny on a phone.
