Tips & Best Practices
Design at 1080x1080 (square) or 1080x1350 (portrait) for the sharpest display quality.
Export as PDF for best compatibility. LinkedIn also supports PPTX and DOCX uploads.
Keep text large (minimum 28px) — carousel slides are viewed on mobile screens.
Limit slides to 10-15 pages for optimal engagement. Longer carousels see drop-off after slide 10.
Add a strong hook on slide 1 and a CTA on the final slide to drive action.
Use consistent branding (fonts, colors, layout) across all slides for a professional look.

PDF Export Settings
When designing LinkedIn carousels in tools like Canva, Figma, or PowerPoint, export as PDF for the best results. Set your canvas to 1080x1080 pixels for square or 1080x1350 pixels for portrait format. In Canva, use "PDF Print" export for higher quality. In Figma, export each frame as PDF and merge. In PowerPoint, set custom slide dimensions to your target pixels, then "Save As PDF." Avoid using standard US Letter or A4 page sizes — while LinkedIn accepts them, these PDFs render at lower effective resolution because the aspect ratio doesn't match mobile screens. Custom pixel-based dimensions ensure every slide looks sharp when viewed on phones and tablets.
Design Tips for Document Carousels
LinkedIn carousels are one of the highest-engagement post types on the platform. To maximize their impact, follow these design principles: Slide 1 is your hook — use a bold headline that creates curiosity or promises value. Avoid starting with your logo or a generic title slide. The first slide determines whether someone stops scrolling and starts swiping. Keep each slide focused on one idea. Use large text (28px+), ample white space, and minimal bullet points. Viewers swipe quickly, so each slide should be digestible in 2-3 seconds. End with a clear CTA on the final slide: follow, comment, share, or visit a link. Carousels that end abruptly without a CTA waste the attention they've earned.
Engagement and Algorithm Impact
LinkedIn's algorithm measures dwell time — how long someone spends looking at your content. Document carousels naturally generate high dwell time because each swipe counts as continued engagement. A 10-slide carousel that someone swipes through fully signals strong interest to the algorithm. Carousels also encourage saves and shares more than single-image posts. The educational, reference-style format makes people want to bookmark the content for later. These engagement signals boost your post's distribution beyond your immediate network. For optimal reach, post your carousel with a strong text introduction (3-5 lines) that previews what's inside. Ask a question or make a bold statement to encourage comments. The combination of high dwell time and active comments is the strongest signal for LinkedIn's algorithm.
