The Ultimate Guide to LinkedIn Image Sizes
First impressions on LinkedIn happen in milliseconds. Long before anyone reads your stellar career history or analyzes your thought-leadership articles, their eyes process visuals. A crisp profile picture, a commanding banner, or a well-proportioned feed post signals instant credibility. Conversely, a pixelated headshot or a banner with cropped-off text whispers neglect.
Because LinkedIn aggressively compresses and crops images that miss the mark, getting the dimensions right is non-negotiable. This comprehensive guide covers every essential LinkedIn image size, ensuring your brand looks pristine across desktop and mobile devices.
1. Profile & Company Page Basics
Your profile is your digital landing page. These two core assets set the tone before a visitor even scrolls down.
- Profile Photo:
- Dimensions: $400 times 400$ pixels (Minimum: $268 times 268$ px)
- Aspect Ratio: 1:1 (displays as a circle)
- Max File Size: 3MB to 8MB (JPG, PNG)
- Pro Tip: Keep your face centered, occupying about 60% to 70% of the frame. Avoid busy backgrounds so your face stays clear even when rendered as a tiny thumbnail in comments.
- Personal Profile Banner (Cover Photo):
- Dimensions: $1584 times 396$ pixels
- Aspect Ratio: 4:1
- Pro Tip: Watch out for the mobile crop and profile picture overlap. Your profile photo sits over the bottom-left corner, and mobile devices chop off the outer edges of the banner. Keep all critical text, branding, and imagery in the center or right-hand side.
- Company Page Banner:
- Dimensions: $1128 times 191$ pixels
- Note: Organization pages use a much wider aspect ratio than personal profiles. Double-check your template before designing!
2. Feed Post Image Sizes
When you share single images in the LinkedIn feed, your format dictates how much screen estate you capture—and on mobile, size equals attention.
| Post Format | Dimensions (Pixels) | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Landscape | $1200 times 627$ | 1.91:1 | Link previews, external article shares |
| Square | $1080 times 1080$ | 1:1 | Clean infographics, standalone quote cards |
| Portrait | $1080 times 1350$ | 4:5 | Maximum mobile engagement, deep-dive graphics |
The Golden Rule for Posts: Because roughly 60% of LinkedIn traffic originates on mobile devices, Portrait ($1080 times 1350$) posts dominate the feed. They force readers to slow down as the image takes up vertical room on their screens.
3. Carousels, Documents, and Articles
LinkedIn allows multi-page document uploads (PDFs) that render as swipeable carousels—a goldmine for organic reach.
- Carousel Slides (Document Shares):
- Dimensions: $1080 times 1080$ pixels (Square) or $1080 times 1350$ pixels (Portrait)
- File Format: PDF (preferred)
- Pro Tip: Design your slides in a tool like Canva using a square or portrait presentation format, export as a standard PDF, and upload via the document icon.
- Article Feature Image:
- Dimensions: $1200 times 644$ pixels
- Pro Tip: This acts as the header visual when publishing long-form LinkedIn Articles. Keep high-contrast text or imagery near the center to guard against minor formatting shifts.
4. Video Specifications
Video content continues to grow across professional feeds. To keep clips from lagging or suffering from poor compression, stick to these parameters:
- Square Video: $1080 times 1080$ pixels (1:1)
- Widescreen Video: $1920 times 1080$ pixels (16:9)
- Vertical Video: $1080 times 1350$ pixels (4:5)
- Specs: MP4 format, maximum file size up to 5GB, and a recommended frame rate of 30fps.
Summary Checklist for Creators
- Use PNG for graphics with text/logos to avoid fuzzy text compression artifacts; use JPG for photographic images.
- Never eyeball dimensions. Set up custom canvas sizes in your design software before starting a project.
- Always preview on mobile. Pull out your smartphone after changing your banner or launching a major campaign to verify that crucial visual details aren’t masked by UI overlays.
