LinkedIn Post Image Dimensions
The LinkedIn post image size depends on the format you choose. The recommended options:
| Format | Dimensions | Best For |
|---|---|---|
| Square (1:1) | 1200 × 1200 px | Default — most screen real estate on mobile |
| Portrait (4:5) | 1080 × 1350 px | Tallest allowed without cropping — even more impact |
| Landscape (1.91:1) | 1200 × 627 px | Link previews, blog header style |
Square (1:1) is the safe default for any image post. Portrait (4:5) is best for statement images, infographics, and quote cards because the extra height keeps the viewer in your post longer.
Link Preview Size
When you share a URL, LinkedIn renders the link's Open Graph image at 1200 × 627 pixels (1.91:1). Set this as your og:image meta tag. If LinkedIn caches an old image, force a refresh with the LinkedIn Post Inspector.
Avoid putting fine text in the link preview image — at the rendered size, anything smaller than 24 px font becomes unreadable on mobile.
LinkedIn Carousel / Document Posts
"Carousel" posts on LinkedIn are uploaded as PDFs. Each PDF page becomes a swipeable slide. This format consistently outperforms regular image posts for B2B content — users dwell longer because they're swiping, not just scrolling past.
- Slide size: 1080 × 1080 px (square) or 1080 × 1350 px (4:5 vertical)
- File format: PDF, DOC, DOCX, PPT, or PPTX
- Max pages: 300
- Max file size: 100 MB
- Recommended length: 6–12 slides (sweet spot for completion rate)
Design the cover slide (first PDF page) with the headline in the top 60% — LinkedIn shows a peek of slide 2 at the bottom of the preview, which cuts off anything below.
Multi-Image Posts
LinkedIn supports up to 9 images in a single post. The grid layout depends on count:
- 1 image: full size, square or 4:5 ideal
- 2 images: side-by-side, both cropped to 1:1
- 3 images: one large left, two stacked right
- 4–9 images: 2×2 or 3×3 grid, all cropped to 1:1
Keep important content in the center of each image — the grid crops aggressively.
Text-Only Posts
Pure text LinkedIn posts have no image dimensions, but they have layout rules:
- The first 3 lines (about 210 characters) appear before the "see more" cutoff
- Use line breaks to create whitespace — solid blocks of text rarely get read
- Maximum post length: 3,000 characters
- Add 3–5 hashtags maximum, placed at the end
File Format Guidance
- JPG: Photos, gradients, scenery — smallest file size
- PNG: Graphics with text, logos, transparent backgrounds — sharpest text
- GIF: Avoid for static images — LinkedIn's GIF compression is much harsher than JPG
- PDF: Carousel/document posts only
Tips for Higher Post Engagement
- Upload at 1200 × 1200 (square) or 1080 × 1350 (4:5 portrait) — never landscape for organic
- Keep critical content in the center 80% of each image
- Use PNG for any image with text; JPG for photos
- For carousels, design vertical (1080 × 1350) and aim for 6–12 slides
- Set og:image at 1200 × 627 for link previews

Frequently Asked Questions
What is the LinkedIn post size?
The LinkedIn post image size is 1200 × 1200 pixels (1:1 square) for maximum feed real estate, or 1080 × 1350 pixels (4:5 portrait) for a slightly taller mobile presentation. Both fit within the LinkedIn feed without cropping.
What is the LinkedIn post aspect ratio?
The recommended LinkedIn post aspect ratios are 1:1 (square) or 4:5 (portrait). Square images take up significantly more screen space than landscape (1.91:1) on mobile, which boosts thumb-stop rate and engagement.
What are the dimensions for a LinkedIn link preview?
LinkedIn link previews use 1200 × 627 pixels at a 1.91:1 aspect ratio. Set this as your Open Graph image (og:image) and LinkedIn will pull it automatically when you paste a link. Use the Post Inspector to refresh the cache.
What is the size for LinkedIn carousels (document posts)?
LinkedIn carousels (also called document posts) display PDF pages at 1080 × 1080 px (square) or 1080 × 1350 px (4:5 vertical). Vertical wins on mobile because it takes up more screen. Upload as a PDF with up to 300 pages and 100 MB total.
What file format should I use for LinkedIn posts?
Use JPG for photos and PNG for graphics with text or transparent backgrounds. Keep files under 5 MB. For carousels, export your slides as a single PDF — LinkedIn re-renders each page as a swipeable slide.
Why does my LinkedIn post image look pixelated?
Pixelated images usually come from uploading below 1200 px wide or letting LinkedIn upscale a smaller image. Always export at the recommended dimensions (1200 × 1200 or 1080 × 1350) and avoid GIF for static graphics — LinkedIn's GIF compression is harsh.
How many images can I attach to a LinkedIn post?
You can attach up to 9 images to a single LinkedIn post. Multi-image posts display in a grid that adapts to image count: one big image, two side-by-side, or a 2×2 / 3×3 grid. All images get cropped to a uniform aspect ratio in the grid view.
What is the best size for a LinkedIn carousel cover slide?
For LinkedIn document/carousel posts, design the first slide (the cover) with the headline in the top 60% — LinkedIn shows the bottom 20-30% as a peek of the next slide. Vertical 1080 × 1350 px makes the cover most impactful in the mobile feed.
