LinkedIn Carousel Size and Specs 2026

If your LinkedIn carousel looks blurry, gets cut off, or fails to upload, the problem is usually the specs. Here is the exact LinkedIn carousel size and format that works in 2026.

Key takeaways

Use 1080 x 1080 px square slides for the safest result.
Upload as PDF if you want multiple slides in one post.
LinkedIn supports PNG and JPG, but PDF gives the carousel behavior.
Keep slide text large: 32 pt minimum for body copy.

LinkedIn carousel specs at a glance

Spec	Recommended value	Why it matters
Dimensions	1080 x 1080 px	Square looks best on mobile and desktop
Aspect ratio	1:1	Avoids cropping on all devices
File type	PDF	Creates the swipeable carousel effect
File size	Under 100 MB	LinkedIn upload limit
Slide count	5–12 slides	Enough depth, not too long
Font size	32 pt minimum	Readable on mobile
Margin	60 px on each side	Prevents text from touching edges

Why PDF beats image files for carousels

LinkedIn treats a PDF upload as a document carousel. Each page becomes a swipeable slide.

PNG/JPG carousel: LinkedIn sometimes compresses heavily and crops edges.
PDF carousel: keeps fonts sharp, layout stable, and formatting consistent.

For best results, export your carousel as a PDF with each slide as a separate page.

Slide count and engagement

Slide count	Best for
3–4 slides	Quick tips, announcements
5–7 slides	How-to, list posts, frameworks
8–12 slides	Deep tutorials, case studies, data breakdowns
12+ slides	Use only when the content is highly valuable

More slides do not mean more engagement. Completion rate drops after 12 slides.

Font, color, and accessibility

Element	Recommendation
Font	Sans-serif: Inter, Roboto, or system fonts
Heading size	48–64 pt
Body size	32–40 pt
Line count per slide	3–5 lines maximum
Color contrast	WCAG AA standard minimum
Alt text	Add to any images for accessibility

Common mistakes to avoid

Wrong aspect ratio — 16:9 slides get cropped on mobile.
Tiny text — anything under 28 pt is hard to read.
No margins — text touching the edge looks unprofessional.
Too many slides — completion drops after 12.
No final CTA slide — always tell the reader what to do next.

Recommended design workflow

Pick a template from the LinkedIn carousel templates guide.
Create each slide at 1080 x 1080 px.
Use a consistent font, color, and layout.
Export as a multi-page PDF.
Upload to LinkedIn with a strong first-line hook.

Tools to create carousels

Tool	Best for
Canva	Non-designers, quick templates
Figma	Teams, reusable components
Adobe Illustrator	Professional designers
BrandOps	AI-generated research + first draft
