Almost every company requires the use of email signatures, and they’re also used by small businesses, freelancers, and anyone who wants their emails to have a more professional look and feel. However, it can be tricky to decide on the perfect size for your email signature. Here’s what you need to know.

What’s the Best Size for Email Signatures?

There’s no set rule on how big or small an email signature should be. That said, 300 x 600 pixels is widely considered to be a good size.

However, there is some wiggle room when it comes to the sizing. For example, if your target market uses mobile more than desktop, you may want to keep your signature to 320 pixels wide for better readability.

What Are the Maximum Email Signature Dimensions?

It’s recommended that you don’t create a email signature bigger than 300 x 700 pixels.

What Format Should Your Email Signature Be?

A best practice to keep in mind when creating your email signature is that you should only use common image formats like PNG or JPEG. Make sure that images are scaled down before you put them into your signature. If you have some coding skills, you can scale them with CSS and HTML.

What Is the Maximum Email Signature File Size?

Again, there are no set rules for maximum email sizes, but generally speaking the smaller the signature is (i.e., fewer kb), the better. Having a large email signature actually uses up more electricity, so if you have a large organization, this cost can add up.

How Do You Pick the Best Size for Your Email Signature?

The best size for an email signature will vary from one business or situation to another, but here a few things for you to consider.

Consider Your Target Market

Take a few minutes to think about your target market and ask yourself a few questions, including but not limited to:

  • Do they read emails on a desktop or mobile?
  • Are they likely to click on social media links?

Think About the Imagery You Use

The imagery you include in your signature is also related to your target market. If you work in a creative field, for example, then larger imagery can work. If your target market is more professional, then you might need to stay away from imagery altogether.

As a quick and fast rule, don’t include huge images as they distract from the actual message.

Some Quick Email Signature Design Tips

Your email signature has two main jobs: to let the reader know as much about you and your business in as little space as possible, and to attract the recipient’s attention – while making sure not to distract them from the email body.

1. Make sure your signature has a responsive design to account for the fact that more and more people are reading and answering their emails on their phones. It’s important for your signature to look great when viewed on different devices.

2. Make sure you include all necessary details including your name, company, title, contact information, and social media profiles. You’d be surprised how many people miss certain information.

3. Keep the design uncluttered for easier reading.

4. Don’t use too many fonts as this can make it difficult to read.

5. Don’t go overboard with images. Try not to add more than one or two images – in this case, less is definitely more.
