LinkedIn social media specs & best practices (2026)
Want your LinkedIn posts to look professional and get noticed? Check out the 2026 specs for images, videos, carousels, and documents (plus easy best practices to make your content shine).
Over the years, LinkedIn has evolved: what started as primarily landscape images has expanded to square posts, carousels, and now vertical videos.
That means your visuals need to adapt, too. Using the right LinkedIn specs ensures your content looks professional, your text is readable, and your message lands exactly as you intended — whether someone is scrolling on desktop or mobile.

Why LinkedIn post specs matter
LinkedIn prioritizes clean visuals, clear text hierarchy, professional presentation, and readability on both desktop and mobile.
Using the correct image size or video format ensures that your content isn’t awkwardly cropped, text stays legible, thumbnails display correctly, documents swipe smoothly, and your brand feels polished and intentional.
LinkedIn best practices in 2026
No gatekeeping here! Follow these tips to make your LinkedIn posts shine.
Think about desktop and mobile
LinkedIn is still big on desktop, but mobile users are growing fast. Make sure your images, videos, and documents look great on both. Keep key elements, like text overlays and logos, centred so nothing gets chopped off.
Pick the right format for your content
Single-image posts are perfect when you want clean, professional visuals.
Multiple images? Carousels are your friend (up to 9 images — just remember to save them as a PDF, or your followers won’t be able to swipe).
PDFs and slide decks work really well for thought leadership, tutorials, or anything that’s a little more detailed. Videos? Square, vertical, or landscape; whatever fits your feed goal.
Add captions to your videos
LinkedIn videos autoplay muted by default, which means many viewers watch without sound.
Adding captions not only makes your content accessible to everyone, including those watching in quiet environments, but it also boosts engagement by helping your message land even when audio isn’t on.
Keep your branding consistent
Using the same colours, fonts, and visual identity across posts makes your brand instantly recognizable.
Canva Pro is a lifesaver here! It lets you design, resize, and keep everything looking cohesive, all with a few clicks.
Use carousel posts strategically
Multi-slide PDFs or documents are amazing for storytelling, reports, or tutorials. Just make sure every slide is consistent in size and style so swiping feels smooth and intentional.
Track what works
Check engagement by post type, format, and timing. What gets saved, clicked, or shared? Pay attention, learn, and double down on the formats your audience loves.
Always do a final human review
If you’re using AI to help with specs, captions, or visuals, make sure a real person reviews everything. A human touch keeps your posts professional, authentic, and true to your brand voice.
Do all this, and your LinkedIn posts won’t just look good — they’ll feel polished, professional, and intentional. Your audience will notice, and engagement will follow.
