Use 1080 x 1350 pixels for most LinkedIn image posts if you want the largest clean feed presence on mobile, and use 1200 x 1200 pixels when you need a safer square format that works almost everywhere. For link previews, use 1200 x 627 pixels. For document-style carousel posts, design each page at 1080 x 1080 or 1080 x 1350. These sizes keep your post sharp, readable, and less likely to be cropped in awkward places.
TLDR: The safest LinkedIn post image size is 1200 x 1200 px, while the strongest mobile feed option is usually 1080 x 1350 px. If you are sharing a blog or landing page, use a 1200 x 627 px image so the link preview does not look stretched or cut off. In a four-week content audit, a B2B consultant switched from wide 1200 x 627 visuals to 1080 x 1350 post images and saw average post dwell time rise by 22% across 16 posts. The image did not do all the work, of course, but the bigger mobile footprint helped.
Recommended LinkedIn Post Image Sizes
LinkedIn accepts several image shapes, but not all perform the same. The best size depends on the post type and where the image will appear. A clean professional graphic can still look poor if the aspect ratio fights the feed layout.
- Square image post: 1200 x 1200 px, 1:1 aspect ratio
- Portrait image post: 1080 x 1350 px, 4:5 aspect ratio
- Landscape image post: 1200 x 627 px, 1.91:1 aspect ratio
- Document carousel page: 1080 x 1080 px or 1080 x 1350 px
- Shared link preview image: 1200 x 627 px
- Minimum practical width: 720 px, though larger is better
If you only want one default size, choose 1200 x 1200 px. It works for personal posts, company page posts, text-heavy graphics, quotes, product screenshots, and simple announcements. If mobile reach matters most, choose 1080 x 1350 px. That format takes up more screen space and gives your copy more room to breathe.
Best Aspect Ratios for Professional Posts
Aspect ratio means the relationship between width and height. It matters because LinkedIn may crop or compress your image when it appears in the feed, on a company page, or inside a preview card.
1:1 square is the dependable choice. It is balanced, easy to scan, and suitable for branded posts. It also reduces the risk of losing key text near the edges.
4:5 portrait is often better for educational posts, checklists, carousels, and thought leadership graphics. It gives you more vertical space. On phones, that extra height can make the post harder to ignore.
1.91:1 landscape is best for link previews and editorial-style images. It is not ideal for dense text because the image appears shorter in the mobile feed. Use it for article thumbnails, event banners, and website preview cards.
The catch is that LinkedIn can display the same asset slightly differently across desktop, iOS, Android, and embedded previews. It drives me crazy that an image can look fine in the composer and then feel a few pixels off once published. That is why safe margins matter.
Resolution, File Type, and Compression
For a polished result, export images at the exact size you plan to use. Do not upload a tiny image and expect LinkedIn to rescue it. It will not. Small images get soft, especially when they contain text, icons, QR codes, or UI screenshots.
- Use PNG for graphics with text, logos, icons, and flat colors.
- Use JPG for photography and complex images with gradients.
- Keep file size reasonable, ideally under 5 MB for faster handling.
- Use sRGB color for consistent display across browsers and devices.
- Avoid heavy compression because it causes blur around letters and logos.
LinkedIn compresses uploaded visuals. That is normal. To reduce damage, upload a crisp original, avoid tiny text, and limit busy backgrounds. A clean image with fewer elements usually survives compression better than a crowded layout.
Safe Zones and Text Placement
Do not place key content at the extreme edges. Keep logos, headlines, faces, and calls to action inside a comfortable safe zone. A margin of 80 to 120 pixels is a good rule for 1080 px or 1200 px designs.
This is especially useful for portrait posts. Some previews may crop slightly. Some users view posts in compact layouts. If your main message sits too close to the top or bottom, expect to waste time fixing and reposting.
- Keep headlines large: Aim for short lines and strong contrast.
- Limit text: One core idea per image is enough.
- Use consistent branding: Colors, logo placement, and type should feel familiar.
- Check mobile first: Most feed scanning happens on phones.
- Leave breathing room: Dense graphics look less credible.
Single Image Posts vs Multi Image Posts
A single image post should be simple and direct. Use it for one claim, one chart, one quote, one product update, or one event message. If the idea needs more explanation, use a document carousel instead.
Multi image posts can work well for event photos, team updates, product sequences, or before-and-after examples. Still, the first image carries the burden. It must explain the reason to swipe or click. If the first image is vague, the rest may never be seen.
For multi image posts, keep all images in the same ratio when possible. Mixing portrait, square, and landscape images can create uneven previews. That looks messy and distracts from the message.
LinkedIn Document Carousel Dimensions
Document posts are often called carousels because users swipe through pages. They are uploaded as PDFs, presentations, or documents. For these, design slides at 1080 x 1080 px for square or 1080 x 1350 px for portrait.
Portrait carousel pages are strong for guides, frameworks, and step-by-step posts. Square pages are safer if your audience uses a mix of desktop and mobile. Either can work, but consistency is critical.
Use one idea per page. Add page numbers. Make the first page feel like a cover, not a generic title slide. A good first page should tell the reader what they will gain in five seconds or less.
Image Sizes for LinkedIn Link Previews
When you paste a URL into a LinkedIn post, the platform pulls a preview image from the page metadata. The best image size for that preview is 1200 x 627 px. This is the common 1.91:1 format used for social sharing cards.
If your preview image looks wrong, the issue may be the website’s Open Graph image, not LinkedIn itself. Update the page image, clear any site cache, then test again. In some cases, LinkedIn may keep an older version for a while. Annoying, yes, but common.
Practical Best Practices for Better Results
Professional LinkedIn visuals should support the message, not decorate it. The feed is crowded. A sharp image earns attention, but clarity earns trust.
- Use a clear hierarchy. Headline first, support detail second, brand mark last.
- Design for skimming. Use short phrases and strong spacing.
- Avoid tiny captions inside the image. Put detailed context in the post text.
- Use real screenshots carefully. Crop them tightly and highlight the key area.
- Test before posting. Send the image to your phone and view it at feed size.
- Track performance. Compare impressions, clicks, comments, saves, and profile visits.
Quick Reference Checklist
- Best all-purpose image: 1200 x 1200 px

A LinkedIn image does not need to be flashy. It needs to be readable, sharp, and sized for the way people actually use the platform. Start with the right dimensions, protect your safe zones, and check every post on mobile before it goes live. That simple process prevents most formatting mistakes and makes your content look more credible from the first impression.
