Key Takeaways
-
Use clear, high-resolution visuals sized correctly for each LinkedIn post format to avoid cropping or blurriness.
-
Single and multi-image posts work best at square or vertical ratios (1080×1080 px or 1080×1350 px) with file sizes under 5 MB.
-
Document carousels support PDFs, PPTs, and DOCs up to 100 MB and 300 pages, making them ideal for guides, checklists, and slide decks.
-
Native videos uploaded directly to LinkedIn get better autoplay performance at 1:1 or 4:5 ratios and hold attention when kept short with captions.
-
Consistent profile visuals – a clear photo, an on-brand header, and the correct banner dimensions, strengthen trust and recognition.
-
Checking metrics like impressions, clicks, and shares helps you understand which formats resonate and guides your future content choices.
Types of LinkedIn Posts
LinkedIn gives you several ways to share ideas, updates, and visuals. Each format has its own strengths, and using them well can help your content reach more people and spark better conversations. Here’s how each type works in practice:
-
Single Image Posts – Upload one strong photo or graphic to highlight an update. For example, you could announce a new product launch with a branded image or share a snapshot from a company event.
-
Multi-Image Posts – Add up to 20 images in one update to tell a story step by step. You can use this for before-and-after project photos, mini tutorials, or highlighting multiple speakers at an event.
-
Document Posts (PDF, PPT, DOC) – Turn a guide, checklist, or presentation into a swipeable carousel. These posts feel like mini e-books in the feed, great for showing your expertise or breaking down complex topics.
-
Native Videos – Upload a clip directly to LinkedIn instead of linking from another platform. Short demos, behind-the-scenes moments, or quick tips work well because video autoplays and grabs attention.
-
Link Shares – Share an article, podcast, or landing page with a preview image and headline pulled automatically from your site. This works best when you pair the link with a personal comment explaining why it's worth a click.
-
Text-Only Posts – Write a short update, insight, or question without any media.
-
Polls – Use LinkedIn's built-in poll tool to ask your audience for input. It's a simple way to do research, get feedback on a product idea, or spark engagement around a topic.
Image & Multi-Image Posts
Photos and graphics are the quickest way to catch someone’s eye on LinkedIn. Getting the LinkedIn post image size right keeps your visuals crisp and stops them from being cropped on mobile or desktop. Here’s how to make the most of single and multi-image posts:
-
Use square or vertical images for more space – A 1:1 ratio (1080×1080 px) fills the feed neatly. A 4:5 ratio (1080×1350 px) takes up more vertical space without cropping.
-
Keep file sizes under 5 MB per image – This prevents upload errors and preserves quality after LinkedIn compresses your file.
-
Tell a story with multiple images – You can add up to 20 pictures in one post. Walk readers through a process, show an event from start to finish, or reveal a product range step by step.
-
Add text or captions carefully – Use clear fonts and high contrast so text stays readable after compression. Save your image at 72–96 dpi to reduce blur.
-
Name your files for SEO – Filenames like "linkedin-image-guide.jpg" can help when people search for visuals online.
Document Carousels (PDF, PPT, DOC)
Sometimes you need more space than a single image or quick text update. LinkedIn lets you upload full documents as swipeable carousels, turning your content into a mini slide deck right in the feed. Done right, these posts showcase your expertise and invite people to swipe through every page.
-
Use PDF for best quality – Although PPT and DOC files work, PDF keeps your fonts, images, and clickable links consistent.
-
Match recommended dimensions – Square pages (1080×1080 px) or portrait pages (1080×1350 px) fill the feed nicely and avoid awkward cropping.
-
Stay within LinkedIn's limits – Up to 100 MB per file and 300 pages total. Keep slides short to encourage swiping.
-
Add a clear cover page – Treat the first page like a book cover, bold title, short subtitle, and your branding so viewers know what they're about to read.
-
Keep design simple – Use high-contrast text and plenty of white space so your message stays readable after compression.
Link Shares (Open Graph)
Sometimes you just want to share an article, a landing page, or a podcast episode. When you paste a link into your update, LinkedIn automatically pulls in a preview image, headline, and description. Done right, this makes your post look neat and inviting instead of messy.
-
Prepare your page with Open Graph tags – Make sure the page you're linking to has a proper title, description, and 1200×627 px image set in its metadata. This prevents broken previews.
-
Write a personal hook above the link – Add a sentence or two explaining why people should click. A genuine comment boosts trust and clicks.
-
Swap the default image if needed – You can upload a different image during post creation if the preview isn't right. Stick to 1.91:1 (1200×627 px) for best results.
-
Keep text short and clear – A crisp headline paired with your own note works better than a long caption.
-
Check the preview on mobile – Always hit "View as" on LinkedIn before posting to see how it looks in the feed.
Native Video Posts
Video grabs attention faster than any other format on LinkedIn. Uploading clips directly, instead of linking from another platform, helps them autoplay smoothly in the feed and makes the algorithm favor your content.
You can also watch how the LinkedIn algorithm reacts to your own video lengths and topics so you refine your approach over time.
-
Use square or vertical ratios for more screen space – A 1:1 (1080×1080 px) or 4:5 (1080×1350 px) video takes up more vertical room on mobile feeds.
-
Keep clips short and clear – Aim for under two minutes when possible. Although the limit is up to 10–15 minutes, depending on your account, shorter videos hold attention better.
-
Stay within LinkedIn's upload limits – Maximum file size is 5 GB. The shortest accepted clip is about 3 seconds.
-
Add captions or subtitles – Most people watch with sound off. Captions make your message clear and boost completion rates.
-
Include a strong opening frame – Treat the first seconds like a thumbnail. Clear headline, readable text, or eye-catching image so people stop scrolling.

Profile Images and Headers
Your profile photo, cover photo, and Page banner work together to create a strong first impression. When these visuals match your posts, your brand feels consistent and trustworthy. Here’s how each one differs and what size to use:
-
Profile Photo (personal or company) – This is the small circular image next to your name. Recommended size: 400×400 px. Use a high-resolution headshot or a clear company logo with plenty of empty space around it.
-
Cover Photo (personal profiles) – Often called the background image, this is the large rectangle behind your profile photo. Recommended LinkedIn cover photo size: 1584×396 px (minimum 1192×220 px). It's great for showcasing your brand colors, a tagline, or an event image.
-
Banner Image (Company Pages) – On LinkedIn Pages, this header is called a banner. Recommended LinkedIn banner specifications: 1128×191 px (minimum 640×220 px).

FAQs | Frequently Asked Questions |
How can I track the reach of my posts?
LinkedIn shows views and other metrics under each update. Understanding what does impressions mean on LinkedIn helps you read these numbers correctly. An impression is every time your post appears on someone’s screen, even if they don’t click or react. Watching impressions over time tells you which content formats and topics are working best.
How do profile visuals affect post-performance?
A clear profile photo and a well-designed header create trust and recognition. When people recognise your brand, they’re more likely to interact with your updates and share them.
Can I add clickable links inside a LinkedIn document post?
Yes. If you upload a PDF with embedded hyperlinks, those links stay active inside the carousel. It’s an easy way to drive readers to your website or resources.
What’s the best size for a LinkedIn carousel cover page?
A square 1080×1080 px page works well. Use a bold title and clean design so it stands out in the feed and invites people to swipe.
