The Ultimate Guide to LinkedIn Image Sizes: Dimensions, Ratios, and Best Practices

First impressions online happen in milliseconds. On LinkedIn, your visual assets—from your profile picture to your daily feed posts and company page banners—speak volumes about your professionalism before a single word is read.

Yet, nothing ruins a polished personal brand faster than a pixelated logo, a banner chopped off at the elbows, or a link preview with its text awkwardly cropped. Because LinkedIn dynamically resizes and crops images across desktop and mobile devices, nailing the correct pixel dimensions isn’t just a technical detail; it is a core strategy for maximizing your reach and engagement.

This comprehensive guide breaks down the exact LinkedIn image sizes you need to make your profile and content look sharp, professional, and optimized.

1. Personal Profile Image Sizes

Your personal profile is your digital storefront. Getting the dimensions right ensures you look approachable and authoritative whether someone views you on a giant desktop monitor or a smartphone.

• Profile Photo: 400 x 400 pixels (1:1 aspect ratio)
  • Tips: LinkedIn displays your profile picture as a circle. Always center your face and keep critical details away from the corners, which get clipped. Upload a high-resolution square image (up to 8 MB in JPG, PNG, or GIF format) so it remains crisp across search results and comment sections.
• Personal Background Banner: 1584 x 396 pixels (4:1 aspect ratio)
  • Tips: This wide canvas is prime real estate for personal branding. However, beware of the overlap: your profile picture sits over the lower-left portion of the banner on desktop (and shifts on mobile). Keep important logos, text, or focal points toward the right side and center of the banner to avoid them being obscured.

2. Feed Post Image Sizes

Since the feed is where most networking and content discovery happen, your post dimensions directly influence how much screen real estate you command.

• Portrait Posts (1080 x 1350 pixels | 4:5 ratio): The Engagement Winner. Because over half of LinkedIn traffic originates from mobile devices, tall portrait images take up maximum vertical feed space, pushing competing content out of view. Use this format for infographics, step-by-step breakdowns, and visual guides.
• Square Posts (1080 x 1080 pixels | 1:1 ratio): The Reliable Standard. Square graphics render cleanly across both desktop and mobile without unexpected cropping. They are ideal for quote cards, product highlights, and versatile graphics that you might also cross-post to other platforms.
• Landscape / Link Previews (1200 x 627 pixels | 1.91:1 ratio): The URL Workhorse. This is the exact dimension LinkedIn pulls for link previews when you share an external article or website. If your preview image doesn’t match this ratio, LinkedIn will automatically crop or letterbox it, often cutting off vital text.
• Carousel / Document Posts (1080 x 1080 pixels per slide | 1:1 ratio): Uploading multi-slide PDF documents (carousels) is one of the most effective ways to drive high engagement. Keep your slides square so they display uniformly on all devices.

3. Company Page and Event Image Sizes

If you are managing a brand, product line, or community hub, company pages require a distinct set of specifications.

• Company Logo: 300 x 300 pixels minimum (400 x 400 pixels recommended for high-DPI screens). Use a transparent or high-contrast PNG file so it stays legible when scaled down to tiny notification icons.
• Company Page Cover Image: 1128 x 191 pixels (~5.9:1 ratio). Unlike the tall personal banner, the company banner is a sleek brand strip. Keep the layout clean, minimalist, and uncluttered.
• Event Banner: 1776 x 444 pixels (4:1 ratio). If you host virtual webinars or live sessions, a custom event banner sets the tone and drives higher registration conversions.

Pro Tips for Flawless Uploads

1. Choose the Right File Format: Stick to PNG for graphics, illustrations, and text-heavy images to keep text sharp and crisp. Use JPG or JPEG for photographs to optimize file size without losing visual quality.
2. Watch Out for Compression: LinkedIn applies its own compression algorithms to uploaded media. Always upload images at or slightly above the recommended pixel dimensions to prevent the platform from aggressively stretching and pixelating your visuals.
3. Design with Mobile in Mind: Because the majority of users interact with LinkedIn via smartphones, always preview your layouts on a mobile screen before hitting publish. Keeping text centered and spacing generous ensures your message is never lost to automatic cropping.
