LinkedIn Logo in Email Signatures: Sizes, Formats, and Setup

A LinkedIn logo in an email signature is the official LinkedIn wordmark or logo lockup placed in the sign-off block of your outgoing emails, linking directly to your LinkedIn profile or company page. It helps recipients recognize and connect with you on the platform while reinforcing your professional identity in every message you send.

LinkedIn is the largest professional network in the world, with over 1 billion members across 200 countries. For most B2B professionals, a LinkedIn presence is not optional. It is where deals start, partnerships form, and reputations get built. But there is a difference between adding a generic blue square to your signature and using the actual LinkedIn logo correctly, following brand guidelines, at the right size, in the right format.

This guide covers the official LinkedIn logo (the full wordmark, not just the "in" icon), including approved sizes, color variations, download sources, and step-by-step setup instructions for Gmail and Outlook. If you are looking for the smaller square icon instead, see our LinkedIn icon guide. For clickable buttons with text, check out the LinkedIn button setup.

What Is a LinkedIn Logo for Email Signatures?

The LinkedIn logo for email signatures is the full brand mark that includes the word "LinkedIn" rendered in the company's proprietary typeface. Unlike the "in" icon (a simple square with the letters "in"), the full logo includes the complete company name and is governed by specific brand guidelines from LinkedIn.

Most professionals use the smaller "in" icon in their signatures because it saves space. But there are situations where the full logo makes more sense, especially for company pages, partnership announcements, marketing signatures, or signatures that need to clearly communicate "find us on LinkedIn" without relying on icon recognition alone.

According to a Demand Gen Report survey, 95% of B2B marketers use LinkedIn for organic content distribution, making it the most widely used professional platform. Adding a recognizable LinkedIn logo to your email signature connects every email you send to the platform where your professional audience already spends time.

LinkedIn Logo vs LinkedIn Icon: What to Use

Before downloading anything, clarify what you actually need. LinkedIn offers two distinct brand assets, and each serves a different purpose in email signatures.

LinkedIn Logo (Full Wordmark)

The full LinkedIn logo displays the complete "LinkedIn" name. It is wider, more prominent, and communicates the platform name explicitly. Use this when:

• Your email signature has space for a wider social media section
• You want to make the platform name immediately clear to all recipients
• You are creating a company signature that links to a company page
• Your audience may not recognize the small "in" icon on its own
• You are including a "Follow us on LinkedIn" call to action

LinkedIn Icon ("in" Bug)

The "in" icon is the compact square mark. It is smaller and works well alongside other social media icons in a row. Use this when:

• Space is limited and you need icons at 20-32px
• You are placing multiple social icons side by side (LinkedIn, X, Instagram)
• Recipients are already familiar with the "in" symbol

For most professional email signatures, the "in" icon is the more practical choice because it fits neatly in a row of social icons. Use the full LinkedIn logo when you want to give LinkedIn special prominence or when the signature design has room for a larger brand mark.

For detailed guidance on using the icon version, see our LinkedIn icon guide.

Official LinkedIn Logo Sizes for Email Signatures

Size matters. A logo that is too large dominates the signature and looks out of proportion. One that is too small becomes unreadable. LinkedIn does not publish specific pixel requirements for email use, but their brand guidelines combined with email signature best practices give us clear targets.

Recommended Sizes by Context

Context	Display Width	Display Height	Source File (2x Retina)	Max File Size
Standalone logo (primary)	120-150px	30-38px	240-300px wide	30KB
Logo alongside social icons	80-100px	20-25px	160-200px wide	20KB
Logo in "Follow us" banner	100-130px	25-33px	200-260px wide	25KB
Mobile-friendly signature	100-120px	25-30px	200-240px wide	20KB

Why Retina Files Matter

Modern screens on MacBooks, iPhones, and high-DPI Windows laptops render images at 2x pixel density. If your logo source file matches the display size exactly, it will appear blurry on these devices. Always export the source file at double the display dimensions and constrain it with HTML width and height attributes.

<!-- Display at 120px, source is 240px for retina clarity -->
<a href="https://linkedin.com/in/yourprofile" target="_blank">
  <img src="https://yourdomain.com/linkedin-logo.png"
       alt="LinkedIn"
       width="120"
       height="30"
       style="display: block; border: 0;" />
</a>

Always set both width and height attributes explicitly. This prevents email clients from rendering the image at its full source dimensions, which would make a 240px file appear twice as large as intended. For a deeper look at signature dimensions, see our email signature logo guide.

Approved LinkedIn Logo Formats and Colors

LinkedIn is specific about how its logo can be used. Violating these guidelines can result in a takedown request, and it signals to recipients that your brand does not pay attention to details.

Color Variations

LinkedIn provides its logo in the following approved color options:

Variation	Use Case	Background
LinkedIn Blue (#0A66C2)	Default, preferred use	White or light backgrounds
White	Reverse/knockout	Dark or colored backgrounds
Black	Print or monochrome contexts	Light backgrounds when color is unavailable

The standard LinkedIn Blue (#0A66C2) on a white or transparent background is the default and preferred version for email signatures. Use the white version only if your signature has a dark background, and the black version only in monochrome contexts where color reproduction is not possible.

Exclusion Zone

LinkedIn requires a clear space around the logo equal to half the height of the "L" in "LinkedIn." In an email signature, this translates to roughly 8-12px of padding on all sides. Do not crowd the logo against text, dividers, or other icons.

What Not to Do

• Do not alter the logo colors beyond the three approved variations
• Do not stretch, compress, or rotate the logo
• Do not add effects like drop shadows, gradients, or outlines
• Do not place the logo on busy or patterned backgrounds
• Do not recreate the logo using a different typeface
• Do not combine the logo with other brand marks in a way that implies endorsement

Where to Download the Official LinkedIn Logo

Never screenshot the logo from the LinkedIn website or pull it from a Google image search. These methods produce low-resolution, improperly cropped files.

Official Source

LinkedIn Brand Resources page: brand.linkedin.com

This is the only official source for LinkedIn logo downloads. The page provides:

• Full LinkedIn logo (wordmark) in PNG and EPS formats
• The "in" icon (bug) in PNG and EPS
• Brand guidelines PDF with usage rules
• Color specifications and exclusion zone documentation

File Format Recommendations for Email

Format	Transparency	Email Support	Recommendation
PNG	Yes	Universal	Best choice for email signatures
JPG	No	Universal	Acceptable if no transparency needed
SVG	Yes	Very poor	Do not use in email
EPS	N/A	None	Source file only, convert to PNG

Download the PNG version from the official brand page. PNG supports transparency, renders crisply at small sizes, and works across every email client. If the official page only offers EPS, open it in a free tool like Canva, Figma, or GIMP and export it as a PNG at your target retina size.

Third-Party Icon Sets

If you are using the LinkedIn "in" icon alongside other social icons, consistency across the icon set matters more than using the official file. Icon sets from sources like Simple Icons, Font Awesome, or custom-designed sets ensure every icon in your signature matches in style, weight, and size. Just make sure the colors stay within LinkedIn's approved palette.

How to Add the LinkedIn Logo in Gmail

Gmail makes it straightforward to add images to your signature, but there are a few details that determine whether the logo displays reliably.

Step-by-Step Setup

1. Open Gmail and click the gear icon in the top right
2. Click See all settings
3. Scroll down to the Signature section under the General tab
4. Select your signature or click Create new
5. Position your cursor where you want the LinkedIn logo
6. Click the image icon in the formatting toolbar
7. Select Web Address (URL) and paste the URL to your hosted LinkedIn logo PNG
8. Click Select
9. Click the inserted logo and choose Small to keep it proportional
10. With the logo still selected, click the link icon in the toolbar
11. Paste your LinkedIn profile URL (e.g., https://linkedin.com/in/yourname)
12. Click OK
13. Scroll down and click Save Changes

Gmail Tips

• Use "Web Address (URL)" over Upload. Gmail re-hosts uploaded images on its own CDN, which can occasionally change URLs. Linking to your own hosted file gives you full control.
• Set the link target. Gmail links open in a new tab by default, which is the desired behavior.
• Test immediately. Send a test email to a personal account and check the logo renders and the link works before deploying to your team.

For a complete Gmail signature walkthrough, see our Gmail email signature guide.

How to Add the LinkedIn Logo in Outlook

Outlook's rendering engine behaves differently from browser-based email clients. The setup process varies between Outlook Desktop, Outlook on the Web, and Outlook for Mac.

Outlook Desktop (Windows)

1. Open Outlook and go to File > Options > Mail > Signatures
2. Select an existing signature or click New
3. Position your cursor where you want the logo
4. Click the image icon in the formatting toolbar
5. Browse to your LinkedIn logo PNG file and click Insert
6. Right-click the inserted image, select Picture > Size
7. Set the width to your target display size (e.g., 120px)
8. Lock the aspect ratio to prevent distortion
9. Click OK
10. Select the image and click the hyperlink icon (or press Ctrl+K)
11. Paste your LinkedIn profile URL and click OK
12. Click Save

Outlook Desktop uses Microsoft Word's rendering engine, which handles images differently from web browsers. Always set explicit pixel dimensions. If the logo resizes unexpectedly after saving, edit the signature HTML file directly at %appdata%\Microsoft\Signatures\.

Outlook on the Web (OWA)

1. Go to outlook.com or your Microsoft 365 webmail
2. Click the gear icon > View all Outlook settings
3. Navigate to Mail > Compose and reply
4. In the signature editor, click the image icon
5. Upload your LinkedIn logo PNG or paste a hosted URL
6. Click the image and drag the corners to resize
7. Select the image and add a hyperlink to your LinkedIn profile
8. Click Save

Outlook for Mac

1. Open Outlook and go to Outlook > Preferences > Signatures
2. Select or create a signature
3. Drag and drop your LinkedIn logo PNG into the editor
4. Double-click the image to access size settings
5. Set the width and height, then click OK
6. Select the image, right-click, and choose Link to add your LinkedIn URL

For the full Outlook setup process, see our Outlook email signature guide.

LinkedIn Brand Guidelines for Email Use

LinkedIn takes brand compliance seriously. Their guidelines apply to any use of the logo, including email signatures. Here are the rules that matter most for signature design.

Required Practices

• Always link the logo to a LinkedIn profile or page. The logo should never appear as a standalone image without a functional link.
• Use the official assets. Download from brand.linkedin.com, not from third-party sources or screenshots.
• Maintain the exclusion zone. Leave clear space around the logo equal to half the height of the "L" character.
• Keep the logo legible. Do not display it smaller than the minimum size specified in the brand guide (typically around 84px wide for the full wordmark in digital contexts).

Common Mistakes to Avoid

1. Using an outdated logo. LinkedIn refreshed its brand in 2019. The current blue is #0A66C2, not the older #0077B5. Check that your file matches the current brand.
2. Recoloring the logo. Matching the logo to your company's brand colors violates LinkedIn's guidelines. The logo must remain in its approved colors.
3. Displaying the logo without a link. A LinkedIn logo that does not link anywhere defeats its purpose and frustrates recipients who expect to click through to a profile.
4. Low-resolution files. A pixelated logo damages your professional image. Always use a retina-ready source file.

Trademark Notice

The LinkedIn name and logo are registered trademarks of LinkedIn Corporation. Using them in your email signature to link to your own profile or company page is a standard, permitted use. You may not use the logo in a way that implies LinkedIn endorses, sponsors, or is affiliated with your company.

HTML Template: LinkedIn Logo in Email Signatures

For teams that manage signatures through HTML, here is a clean, email-client-safe snippet that works across Gmail, Outlook, and Apple Mail.

<table cellpadding="0" cellspacing="0" border="0" style="border-collapse: collapse;">
  <tr>
    <td style="padding: 8px 0;">
      <a href="https://linkedin.com/in/yourprofile"
         target="_blank"
         rel="noopener noreferrer"
         style="text-decoration: none;">
        <img src="https://yourdomain.com/linkedin-logo.png"
             alt="LinkedIn"
             width="120"
             height="30"
             style="display: block; border: 0; outline: none;" />
      </a>
    </td>
  </tr>
</table>

Template Notes

• Table-based layout is required for consistent rendering in Outlook, which ignores most CSS layout properties.
• border: 0 and outline: none prevent blue link borders that some clients add around linked images.
• display: block eliminates extra whitespace below the image in Gmail and webmail clients.
• rel="noopener noreferrer" is a security best practice for external links opening in new tabs.
• Alt text ensures "LinkedIn" appears even when images are blocked by corporate email policies.

Frequently Asked Questions

What size should the LinkedIn logo be in an email signature?

The ideal display width for a LinkedIn full wordmark logo in an email signature is 120 to 150 pixels wide and 30 to 38 pixels tall. Your source file should be double those dimensions (240 to 300 pixels wide) so the logo renders sharply on retina and high-DPI screens. Keep the file size under 30KB. If you are using the logo alongside other social icons in a row, scale down to 80 to 100 pixels wide so it stays proportional with the rest.

Can I change the color of the LinkedIn logo to match my brand?

No. LinkedIn's brand guidelines restrict the logo to three approved color variations: LinkedIn Blue (#0A66C2) on light backgrounds, white on dark backgrounds, and black for monochrome print contexts. Recoloring the logo to match your company's palette violates the trademark guidelines and can result in a takedown request. If brand color consistency is important, consider using a custom-styled icon set, but ensure LinkedIn remains in one of its approved colors.

What is the difference between the LinkedIn logo and the LinkedIn icon?

The LinkedIn logo is the full wordmark that spells out "LinkedIn" in the company's typeface. The LinkedIn icon (also called the "in" bug) is the compact square mark containing only the letters "in." The full logo is wider and more explicit, making it ideal when you want to clearly name the platform. The icon is smaller and better suited for placement in a row of social media icons. Most email signatures use the icon for space efficiency, but the full logo works well for standalone placements or company-focused signatures.

Where can I download the official LinkedIn logo for free?

The official source is LinkedIn's Brand Resources page at brand.linkedin.com. This page provides the logo in PNG and EPS formats, along with the full brand guidelines covering colors, exclusion zones, and usage restrictions. Do not source the logo from Google image searches, screenshots of the LinkedIn website, or unofficial icon packs, as these often have incorrect colors, poor resolution, or outdated designs.

Should I use the LinkedIn logo or icon in my email signature?

For most email signatures, the "in" icon is the practical choice. It takes up less space, fits neatly alongside other social icons, and is widely recognized by professionals. Use the full LinkedIn logo when you want to give LinkedIn special visibility, when the signature design has room for a larger brand mark, or when your audience may not recognize the small icon. Company signatures that link to a LinkedIn company page often benefit from the full logo because it adds context that the icon alone does not provide.

Key Takeaways

1. Use the full LinkedIn logo when you want prominence. The wordmark clearly communicates the platform name, which is ideal for company signatures, partnership announcements, or standalone social links.
2. Size the logo at 120-150px wide for display and export the source file at 2x (240-300px) for retina screens. Always set explicit HTML width and height attributes to prevent email clients from rendering the image at full source size.
3. Download from the official brand page only. The approved source is brand.linkedin.com. Use PNG format for email because it supports transparency and works across every client.
4. Stick to LinkedIn's approved colors. LinkedIn Blue (#0A66C2) on light backgrounds, white on dark backgrounds, or black for monochrome. Never recolor the logo to match your own brand palette.
5. Always link the logo to your profile. A LinkedIn logo without a hyperlink wastes space and frustrates recipients who expect to click through. Wrap the image in an anchor tag pointing to your LinkedIn URL.
