Fonts matter. As you take a look at this blog post on your screen, are you thinking about the font used? If this blog post were written in Papyrus, that might make for a distracting read. For email signatures, the font you choose is even more pertinent because it is your sign off. If you sign off an email using Comic Sans, the impression you leave might be childish and unprofessional. 

However, you can set the optimal tone in your email by selecting the best signature font.

That’s why in this blog post, we’ll cover:

When you sign off from a professional email account, you are also representing the company or organization you work for. Choosing a professional signature font shows you and the place you work for in a positive light.

While an email signature may seem straightforward, there are many factors to consider when choosing a signature font: the size, color, and font itself. In this section, I will cover what to look for.

Size matters for readability. Too small, and the reader won’t be able to see it. At the same time, you don’t want your font to be so large that it becomes obtrusive. You most certainly don’t want the font size of your signature to overpower the body text. The recommended font size for your email signature is 11 to 13.

When it comes to color, aim for legibility. Colors too light like yellow or too bright like red make your email signature hard to read. Choose classic colors like black or navy blue. It also helps to make your email signature the same color as the email body for consistency. Try not to use too many colors — it is best to use 2 to 3 at most to avoid overwhelming the reader.

The wrong font can leave a negative impression on the reader. Using a heavily stylized font can hinder legibility. Custom fonts may not be compatible across different platforms. 

The following fonts meet the requirements for legibility and compatibility across different platforms. 


An email signature may be the last part of your email, but that doesn’t mean it should be an afterthought. Your attention to detail will pay off. Selecting the right font can help you convey your personality and professionalism, leaving a lasting impression.
