A B2B software company was running paid LinkedIn ads. Their targeting was excellent — reaching the exact personas they needed. Their click-through rate was poor. A consultant reviewing the campaign pointed to the company logo: it was showing as a blurry 4-pixel-high square in the sponsored content feed, next to competitors whose logos were crisp and clear.
The small logo size in LinkedIn ads is a known and unavoidable constraint. What's avoidable is your logo being blurry at that small size because the source file wasn't prepared correctly.
LinkedIn is the highest-stakes professional network for most B2B companies, professional services firms, and anyone whose clients are other businesses. How you show up there — including your logo — contributes directly to whether prospects trust you enough to engage.
Here are all the places your logo appears on LinkedIn and exactly how to prepare for each.
The Six Places LinkedIn Displays Your Logo
1. Company Logo (Square, 300x300)
This is the primary logo asset on your company page. It appears:
- On your company profile page (large)
- In follower feeds when you post updates
- In search results when someone searches for your company
- In employee profiles (under "Experience")
- In sponsored content (small)
Required size: 300x300 pixels minimum Recommended: 400x400 pixels Format: PNG or JPEG (PNG recommended for transparency support) Aspect ratio: Square (1:1) — LinkedIn will not accept non-square images here
This is where the circular-crop issue comes in: LinkedIn displays this logo as a square, not a circle, which is better than some platforms. However, if your logo has thin margins, the platform's rounded-corner clipping can cut the edges.
Leave 8–10% padding on each side. For a 400x400 upload, keep your logo within 320x320 pixels centred.
2. Cover Image (Banner)
The cover image appears at the top of your company page when someone visits it directly.
Required size: 1128x191 pixels (approximately 6:1 ratio) Maximum file size: 8 MB Format: PNG or JPEG
This is a very wide, very short banner. Most companies put a tagline, their logo (if horizontal), and a brand-coloured background here. The constraint is the unusual aspect ratio — a horizontal logo works well here, but your design needs to be purpose-built, not cropped from a wider image.
Keep important content in the central 700px horizontally — LinkedIn compresses the sides on smaller screens.
3. Sponsored Content Logo (Tiny)
When you boost posts or run sponsored content, your logo appears as a small square next to your company name in the ad. This is typically shown at around 40–50px.
This is the context where the B2B software company above had trouble. At 40px, only the cleanest, most high-contrast icon marks are recognisable. A wordmark is completely illegible at this size.
You can't upload a separate image specifically for sponsored content — LinkedIn uses your company logo. This means your 300x300 company logo must be designed to work at 40px. Use only your icon mark, not a full wordmark, for the company logo square.
4. Employee Profile Logo (Experience Section)
When employees list your company in their LinkedIn profiles, your company logo appears next to the job title. This displays at approximately 40-50px.
Same constraint as sponsored content: the logo must work at tiny sizes. An icon mark always performs better than a wordmark here.
5. LinkedIn Learning (if applicable)
If you run LinkedIn Learning courses or use LinkedIn's talent products, your logo appears in additional contexts with similar 300x300 constraints.
6. LinkedIn Jobs Logo
When you post jobs, your logo appears in the job listing both on LinkedIn's job board and in job emails sent to candidates. First impressions for talent acquisition matter — a professional logo builds confidence in the role and the company.
Preparing the Right Files
For LinkedIn, you need two prepared files:
File 1 — Company Logo (300x300 or 400x400):
- Your icon mark only — no wordmark
- Centred with 10% padding on all sides
- Solid brand-colour background or white background (no transparent PNG — LinkedIn renders transparency as grey or white depending on context)
- PNG at 400x400 pixels
Why no wordmark: At every small display context (ads, employee profiles, search results), a wordmark is illegible. The company logo needs to function as an icon — a brand symbol that communicates identity at 40px. For B2B brands without an icon mark, a bold lettermark (initials) styled in your brand font is better than a tiny, unreadable wordmark.
File 2 — Cover Image (1128x191):
- Horizontal layout
- Brand colour background (or photo)
- Full wordmark or logo lockup (horizontal version ideal)
- Your tagline or key brand message optional
- Important content kept in central 70% of the width
Why Your LinkedIn Logo Matters More Than You Think
Profile visits from cold outreach
When someone receives a LinkedIn connection request or InMail from an employee of your company, they check the company page. If the company logo looks unprofessional or is missing, the cold outreach immediately loses credibility. A clean, professional logo is part of the trust stack.
LinkedIn SEO (Company Page Visibility)
LinkedIn has its own search algorithm. Completeness of your company page — including logo, cover image, and all profile fields — affects whether your company appears in "Companies to follow" suggestions and in search results.
Content engagement signals
LinkedIn's algorithm gives more organic reach to content from pages with complete profiles and consistent branding. A missing or blurry logo signals an inactive or unprofessional page.
B2B decision maker impressions
LinkedIn research shows that purchase decisions in B2B are heavily influenced by the perceived professionalism of a vendor's online presence. For a company selling to enterprise clients, a poor LinkedIn presence — including a bad logo — is a real friction point in the sales process. The post on logo design for B2B companies covers this trust dynamic in depth.
Common LinkedIn Logo Mistakes
Using the full horizontal wordmark as the company logo. This fails at every small display context. Create a separate square icon mark for this specific use.
Low-resolution upload. Uploading a 200x200 logo to a 300x300 field. The image is upscaled by LinkedIn and looks blurry. Always upload at the recommended resolution or larger.
White logo on white background. LinkedIn's interface is mostly white. A white-background PNG with a white logo is invisible. Use a brand-colour background behind the icon mark.
Not updating after a rebrand. LinkedIn company page logos have a habit of being forgotten during brand updates. Add LinkedIn to your rebrand rollout checklist — the 30-day brand rollout plan specifically covers this.
No cover image. A company page without a cover image shows a grey default banner. It looks abandoned. A simple branded banner takes 30 minutes and significantly improves the page's professional appearance.
Logo System for LinkedIn
LinkedIn is one of the reasons every brand needs a square icon mark as part of their logo system. The responsive logo design guide explains how a complete logo system works — and why the icon mark isn't optional for digital brands.
If your current logo is a wordmark only, designing a companion icon mark is a straightforward project. If your logo needs cleanup or your file set doesn't include a proper square version, our logo cleanup service prepares the complete file set.
Get LinkedIn-Ready Logo Files
We prepare every file your LinkedIn company page needs — square icon, horizontal banner, clean formats for every placement.
300x300 pixels minimum, 400x400 recommended. Must be square (1:1 aspect ratio). LinkedIn will not accept non-square images for the company logo. PNG format is recommended — it supports clean edges for logos with solid colours and sharp typography.
LinkedIn shows your company logo at approximately 40–50 pixels in sponsored content. If your source file is a wordmark or a complex logo with fine detail, it will blur at that size. Use only your icon mark — a simple, high-contrast symbol — as your LinkedIn company logo.
1128x191 pixels. This is a very wide, short banner (about 6:1 ratio). Design specifically for this format — don't use a cropped version of another image. Keep important content in the central 700px because LinkedIn clips the sides on mobile.
LinkedIn renders the company page slightly differently on mobile and desktop. The most common issue is the cover image being cropped. Keep your logo and all important text in the central 70% of the cover image width. The square company logo renders consistently across devices.
No. LinkedIn renders transparency as white or grey depending on context. Use a solid brand-colour or white background. Transparent backgrounds cause logos to look inconsistent or disappear against certain LinkedIn interface backgrounds.
Yes, indirectly. LinkedIn considers page completeness in its company search algorithm. A complete profile — including logo, cover image, and all description fields — performs better in LinkedIn's 'Companies you may want to follow' suggestions and company search results.
Quick Answers
LinkedIn says my company logo is the wrong size. What does it need?
It needs to be square — same width and height. Minimum 300x300 pixels. If you're uploading a horizontal logo, crop to square around the icon mark with padding, or create a dedicated square version.
My logo looks fine on the company page but tiny and blurry in my LinkedIn posts.
The post thumbnail uses your 300x300 company logo at a small display size. If it's blurry, your source file is too low resolution. Upload a cleaner 400x400 image with only the icon mark — no wordmark.
Can I use my wordmark as the LinkedIn company logo?
You can upload it, but it won't be effective. At 40–50px display size in ads and employee profiles, a wordmark is unreadable. An icon mark or bold lettermark always performs better.
How do I update my LinkedIn company logo?
Go to your LinkedIn Company Page, click Edit Page, and update the Logo Image in the Overview section. Changes take a few minutes to propagate across LinkedIn's interface.
Does LinkedIn automatically create a company page for my business?
LinkedIn creates basic company entries from employee data. These auto-generated pages often have no logo or branding. Claim and complete your company page to control how your brand appears.
