The Ultimate Guide to LinkedIn Image Sizes: Stop Letting Bad Formatting Ruin Your Professional Brand

First impressions online happen in milliseconds. When a potential client, hiring manager, or future business partner lands on your LinkedIn profile or scrolls past your post, they don’t read your copy first—they look at your visuals.

Yet, nothing kills digital credibility faster than a blurry, awkwardly cropped profile picture, a banner with cut-off text, or an infographic chopped in half by LinkedIn’s automated formatting.

To help your personal brand and business presence stand out for all the right reasons, this comprehensive guide breaks down every exact dimension, aspect ratio, and golden rule you need to master LinkedIn image sizes.

Part 1: Personal Profile Branding

Your personal profile is your digital home base. Every image here must project absolute professionalism.

1. Profile Picture

• Optimal Dimensions: 400 x 400 pixels (Minimum: 268 x 268 pixels)
• Aspect Ratio: 1:1 (Perfect square)
• Max File Size: 8 MB
• Formats: PNG or JPEG

Pro Tips: LinkedIn applies a circular crop to your profile photo, which means your hard corners are eliminated. Center your face and keep essential features within the middle 60% of the frame. Avoid uploading images smaller than 300×300 pixels; otherwise, LinkedIn will force an upscale, resulting in a pixelated, blurry look.

2. Personal Background Banner

• Optimal Dimensions: 1584 x 396 pixels
• Aspect Ratio: 4:1 (Landscape)
• Max File Size: 8 MB
• Formats: PNG or JPEG (PNG-24 is recommended if your banner contains sharp text or logos)

Pro Tips: Your background banner is prime digital real estate, yet many users leave it blank or default blue. Use it to showcase your value proposition, a key achievement, or your company branding. Beware of mobile cropping: personal banners display fully on desktop but automatically crop on smaller mobile screens. Keep your critical text and logo within a centered 1200 x 300 pixel safe zone. Furthermore, remember that your profile photo overlaps the bottom-left corner of the banner (and shifts toward the center on mobile), so keep that area clear of text.

Part 2: LinkedIn Company Page Specs

If you manage a business page, separate rules apply. Company dimensions differ slightly from personal profiles.

• Company Logo: 300 x 300 pixels (1:1 ratio, max 4 MB). Tip: Use a transparent PNG for a cleaner look.
• Company Cover Banner: 1128 x 191 pixels (approx. 5.9:1 ratio, max 8 MB). Note that this is much wider and shorter than a personal banner, so do not try to reuse the same asset.
• Life Tab Main Hero Image: 1128 x 376 pixels (3:1 ratio).

Part 3: Feed Post Image Sizes (The Engagement Drivers)

Your feed content is where image dimensions have the most direct impact on visibility and engagement. Depending on your content type, choose one of these standard formats:

1. Square Posts (The Reliable Default)

• Dimensions: 1080 x 1080 pixels (or 1200 x 1200 pixels)
• Aspect Ratio: 1:1
• Best For: General announcements, product showcases, quote graphics, and content repurposed from Instagram.
• Why it works: Square posts display consistently across desktop and mobile feeds without unexpected cropping.

2. Portrait / Vertical Posts (The Mobile-First Power Play)

• Dimensions: 1080 x 1350 pixels (or 1200 x 1500 pixels)
• Aspect Ratio: 4:5
• Best For: Infographics, step-by-step breakdowns, and deep-dive visual summaries.
• Why it works: Because over half of LinkedIn browsing happens on smartphones, a 4:5 vertical image consumes significantly more screen space. It forces competing content out of view, maximizing user attention as they scroll.

3. Landscape Posts & Link Previews

• Dimensions: 1200 x 627 pixels
• Aspect Ratio: 1.91:1
• Best For: Data visualizations, landscape photography, and automatic link previews.
• Why it works: Whenever you share an external URL, LinkedIn looks for this exact dimension to construct the preview card. If your source code’s Open Graph (OG) meta tags don’t supply a 1.2:1 or 1.91:1 image, LinkedIn will awkwardly guess a crop, often cutting off important elements.

4. Multi-Image & Document Carousels

• Multi-Image Grid (2–9 images): Upload standard square 1080 x 1080 pixels images for clean grids.
• Document / Carousel Cover Page: 1200 x 1500 pixels (4:5 ratio) ensures your PDF or slide deck preview looks prominent and legible in the feed.

Summary Golden Rules for Success

1. Never Upscale Tiny Images: If an image is too small, creating a larger canvas and stretching it will only introduce pixelation and blurriness. Always design at or above the target resolution.
2. Design with Mobile in Mind: Because the majority of professionals check LinkedIn on mobile devices, portrait-style post layouts (4:5) and centered banner safe zones guarantee your message won’t get cut off.
3. Save in the Right Format: Use crisp PNG files for graphics, logos, and images containing text to avoid compression artifacts, and high-quality JPEGs (85-95% quality) for photographic content to keep file sizes manageable.

By aligning your assets with these precise specifications, you project immediate polish, professionalism, and attention to detail—ensuring your personal brand or business shines brightly in every feed.
