How to Add Social Media Icons to an Email Signature
Enhance your email signature by adding social media icons. Discover step-by-step instructions to turn every email into a powerful marketing tool.

Scrolling through your LinkedIn feed, you’ve probably noticed some posts that just grab your attention. Beyond a great lead photo or a killer opening line, some use different text styles to stand out. This guide will show you exactly how to change the font in your LinkedIn posts using simple tools. More importantly, it will cover the best practices for using these styles to boost your brand without looking unprofessional.
In a sea of posts that all look the same, even a small visual change can make an impact. The default LinkedIn font is clean and professional, but it offers zero room for variation. Intentionally changing the font on specific words or phrases is about more than just aesthetics, it's a communication strategy. Think of it as the digital equivalent of using a highlighter on a document. It helps you:
Using different fonts is a tool, and like any tool, the key is knowing how and when to use it for maximum effect.
LinkedIn doesn't have a built-in font editor like Microsoft Word. You can't just highlight text and click an "Italic" or "Bold" button. The secret to changing your font lies in using special characters from a system called Unicode. Essentially, you'll be using characters that look like letters styled in different fonts but are technically unique symbols. For example, understanding how to bold text in a LinkedIn post uses this principle.
But you don't need to know any of the technical details. All you need is a free online font generator. These websites do all the work for you.
Here's how to get it done in under a minute:
That's it! It’s really that simple. You’re just copying special text characters and pasting them where you want them.
Now that you know how to do it, it's time to learn how to do it well. Going overboard with custom fonts can make your posts hard to read, look unprofessional, or even be inaccessible to some users. Follow these guidelines to use them effectively and professionally. These tips will also help you learn how to format LinkedIn posts for engagement.
The goal isn't to write your entire post in a crazy script font. The most effective use of custom fonts is for highlighting small, important pieces of information. Use them for:
Think of them as seasoning, not the main course. One or two style variations per post is plenty.
This is the most important rule. Since these "fonts" are actually Unicode symbols, screen readers (software used by people with visual impairments) may not interpret them correctly. A screen reader might read "𝐑𝐞𝐚𝐝 𝐦𝐨𝐫𝐞" as "mathematical double-struck capital r, mathematical double-struck capital e, mathematical double-struck capital a..." or simply skip it entirely.
To keep your content accessible:
Over half of LinkedIn users browse on their phones. A font that looks great on your large desktop monitor might render as tiny, unreadable text or even show up as empty boxes (called "tofu") on someone's mobile device if their phone doesn't support that specific character. Before you publish, copy your post text and send it to yourself in a message to see how it looks on your phone.
A fun, bubbly font might be perfect for a graphic designer promoting their creative services, but it would feel jarring coming from a mergers and acquisitions lawyer. The font styles you choose should align with your professional brand. Learning how to optimize your LinkedIn profile is key to maintaining this professional image. When in doubt, stick to clean, simple bolds and italics. They add emphasis without drastically changing the personality of your post.
Changing your font isn't the only way to create visual interest. Often, a compelling post is simply one that’s easy to read and draws the eye where you want it to go. Here are a few other formatting tricks to make your content pop:
Emojis aren't just for casual chats anymore. On LinkedIn, they can serve a professional purpose. Discover how to add emojis to a LinkedIn post effectively:
Like fonts, moderation is key. A couple of strategically placed emojis add color and context, but a whole string of them can look like spam.
The easiest and most underrated formatting tool is the "Enter" key. Big, dense paragraphs are intimidating. Break your ideas down into short, single-sentence paragraphs. This forces the reader to slow down and makes your content feel airy and easy to digest, especially on a mobile screen.
Instead of writing like this, which feels dense and can make a reader lose their place if they look away for even a second.
Consider writing like this.
Each key point gets its own line.
It makes the entire post feel much less daunting.
And it forces you to be concise.
Remember that the first and easiest option generated by most font tools is a simple bold style. It’s highly readable, professional, and draws the eye effectively without running into the accessibility problems of more obscure fonts. When in doubt, this is almost always your best choice.
Mastering these simple formatting techniques will help you control the reader's journey through your post, making your content more engaging and impactful.
Switching up the font in your LinkedIn posts is a great way to add emphasis and inject personality into your content. By using font generators and keeping principles of readability and moderation in mind, you can effectively make your message stand out on a crowded feed.
While a unique font can make a single post pop, building a recognizable brand on LinkedIn comes from consistently showing up with valuable content. At Postbase, we designed our platform to make that consistency feel second nature. Planning your entire content strategy on one visual calendar helps you focus on what really matters - creating great content and connecting with your audience.
