Master Your Visuals: The Definitive LinkedIn Post Image Size Guide
Nothing kills the momentum of a brilliant post faster than an image that looks fuzzy, awkwardly cropped, or squished by LinkedIn’s auto-formatter. Because a vast majority of professionals view LinkedIn on mobile devices, your images need to look crisp, professional, and intentional whether readers are scrolling on a massive desktop monitor or a smartphone on the go.
Whether you are designing infographics, sharing campaign snapshots, or polishing your personal brand, getting the dimensions right is the easiest way to immediately elevate your content’s credibility.
LinkedIn Post Dimensions at a Glance
| Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Square Feed Post | 1080 x 1080 px (or 1200 x 1200 px) | 1:1 | Universal standard, quote cards, infographics |
| Portrait Feed Post | 1080 x 1350 px | 4:5 | Mobile-first content, tall infographics, high engagement |
| Landscape / Link Preview | 1200 x 627 px | 1.91:1 | Sharing website URLs, landscape photography |
| Carousel / Document | 1080 x 1080 px | 1:1 | Multi-slide PDFs, step-by-step guides |
| Profile Photo | 400 x 400 px | 1:1 | Personal branding, circular display |
| Background Banner | 1584 x 396 px | 4:1 | Profile header space, value proposition |
Choosing the Right Feed Format
When publishing single images to your feed, you have three primary orientation choices. Each behaves differently in the scroll.
1. Square (1080 x 1080 px) — The Reliable All-Rounder
If you aren’t sure what layout to choose, square is your safest bet. It displays consistently across desktop and mobile without unwanted cropping, occupying a clean, balanced block of the feed. It works brilliantly for quotes, product announcements, and graphics you plan to cross-post to other platforms like Instagram or X.
2. Portrait (1080 x 1350 px) — The Mobile Engagement Engine
If your main goal is capturing attention, portrait orientation is your secret weapon. Because it stretches vertically, a portrait image takes up significantly more screen space on mobile phones, pushing competing posts out of view. Creators and brands relying on data-heavy infographics or deep-dive visual storytelling see substantially higher dwell times with this format.
3. Landscape (1200 x 627 px) — The Link Preview Standard
This wider, shorter format mirrors LinkedIn’s native link previews. Whenever you drop a URL into a post, LinkedIn pulls an Open Graph image to generate a card. If your link preview image matches the 1.91:1 ratio, it fills the card cleanly instead of forcing awkward white padding on the sides.
Beyond the Feed: Profile and Page Dimensions
Your overall profile or company page creates the immediate impression visitors get when they click your name.
- Profile Picture (400 x 400 px): LinkedIn crops your profile photo into a circle. Keep your face centered, maintain a high-resolution file, and avoid crowding the outer corners where the circular mask cuts off your edges.
- Background Banner (1584 x 396 px): This wide banner spans the top of your profile. Keep in mind that your profile photo and headline overlap the lower-left portion of the banner on desktop (and shift slightly on mobile). Leave that corner clear of critical text or logos.
Pro Tips for Flawless LinkedIn Visuals
- Match Your File Format to the Content: Use PNG for graphics, UI mockups, and text-heavy images to keep text crisp and prevent fuzzy compression artifacts. Use JPG for standard photographs to keep file sizes low.
- Respect the Safe Zones: Different devices crop margins slightly differently. Never crowd text, logos, or critical data points right against the outer edges of your design canvas.
- Keep File Sizes Lean: LinkedIn supports images up to 5 MB, but compressing files to under 2 MB ensures your content loads instantly for users on slower cellular connections.
By aligning your assets with these specifications, you ensure your professional insights take center stage without visual distractions.
