Why the right LinkedIn sizes matter

LinkedIn is the leading B2B social media platform for many German SMEs. Decision-makers, specialists and potential employees meet here – which is why a professional appearance is not a Nice-to-Have, but part of your corporate communications.

Image and video formats directly influence reach, engagement and brand perception. Pixelated photos, cropped logos or the wrong aspect ratio signal a lack of care – even when the content itself is strong. The right LinkedIn dimensions help you avoid these mistakes and make the most of every post. LinkedIn is no exception.

Profile and company page: fundamentals

Your profile and company page are the first touchpoints. Before anyone reads a post, they see your profile picture, cover image and branding. These elements should therefore follow your corporate design and the current LinkedIn image size specifications.

For personal profiles, the profile photo should be 400 x 400 px (1:1). Center faces or logos and leave a little margin, because LinkedIn displays the image in a circle. The cover image (banner) is recommended at 1584 x 396 px. Place logos and key messages in the center – outer areas may be cropped on mobile devices.

Company pages differ slightly: the logo is also recommended at 400 x 400 px, while the page cover often works best at 1128 x 191 px or as a high-resolution version up to 4200 x 700 px. Keep text-free zones in mind, maintain sharpness and use consistent colors and typography. This is how you optimize your LinkedIn company page for a trustworthy first impression

Formatting LinkedIn feed posts correctly

Most LinkedIn content appears in the feed. Here, format decisions determine whether your creatives use the available space or appear small with padding. For link posts with URLs, LinkedIn explicitly recommends a 1.91:1 ratio, as 1200 x 627 px is the established benchmark.

For pure image posts, square formats (1080 x 1080 px or 1200 x 1200 px, 1:1) often work well because they take up more vertical space in the feed. Portrait formats (1080 x 1350 px, 4:5) are increasingly suitable for mobile-first content. Use high-contrast creatives, clear headlines and a visible call to action, as around 70% of LinkedIn usage takes place on smartphones.

Our article on common mistakes in social media formats explains why mobile optimization and safe zones are so important across platforms.

Common LinkedIn post sizes:

Landscape / link preview: 1200 x 627 px (1.91:1)
Square: 1080 x 1080 px or 1200 x 1200 px (1:1)
Portrait: 1080 x 1350 px (4:5)
Document carousel (PDF): 1080 x 1080 px or 1080 x 1350 px per page

Videos, documents and carousels on LinkedIn

Video is becoming increasingly important on LinkedIn – especially for thought leadership, employer branding and product explanations. LinkedIn supports different aspect ratios: 16:9 for classic presentations, 1:1 for compact messages and 9:16 for mobile-first clips.

The 9:16 format in particular is worth highlighting in 2025/2026. Vertical videos use the smartphone screen efficiently, feel native in the feed and can also be reused for Instagram Reels or TikTok with little extra effort. Make sure file sizes and lengths remain within platform limits and that subtitles are readable even without sound.

PDF carousels are ideal for checklists, studies or step-by-step guides – i.e. content with real added value. Plan one slide per insight, use 1080 x 1080 px or 1080 x 1350 px per page and a maximum of around ten slides. This turns expert knowledge into a swipeable format that encourages saves and shares.

What to consider for LinkedIn ads

Paid reach on LinkedIn is especially relevant for B2B targeting. Sponsored Content uses essentially the same image and video dimensions as organic feed posts. So your organic templates can often be reused for ads.

Carousel ads work with 1080 x 1080 px per card (up to ten slides). Message Ads and Conversation Ads require compact creatives that remain readable in the chat context. Dynamic Ads use small but brand-defining graphics. Logos and faces should be sharp even at thumbnail size.

Test variants in A/B tests and maintain a consistent corporate identity. This increases recognition and makes your LinkedIn ad formats more efficient in the long run.

Events, groups and all key sizes at a glance

Events and groups are easily overlooked in everyday LinkedIn work, yet they influence perception as well. Event covers are typically recommended at 1200 x 627 px. Place core messages in the center so they remain visible on mobile.

Group headers often use wide banner formats (for example 1776 x 444 px). Check the preview before publishing, because cropping varies by device. LinkedIn adjusts image specifications from time to time. So review official guidelines regularly.

For other channels, see our dedicated size guides – for example the Instagram Size Guide or TikTok Size Guide. The differences are significant.
