Fortunately, there are solutions to fix this Gmail signature issue so you can continue sending emails with your preferred signature.  

What does the Gmail signature too long error message mean?

You'll have copied and pasted your email signature into Gmail, getting you one of the following error messages:

What is the maximum length for a Gmail signature?  

According to Google, the maximum length for a Gmail signature is 10,000 characters. This includes any text, images, and formatting you may have in your signature.  

What causes the Gmail signature too long error?  

There are a few different reasons why you might be getting this error message: 

  • Special formatting in email signatures: Using bold, italics, or colored text can increase character count, potentially exceeding signature limits. 

  • Images and logos in email signatures: Including high-resolution images or multiple logos can quickly add to the character count and trigger an error. 

  • Copying and pasting email signatures: Copying from other documents or websites may introduce hidden formatting issues, leading to errors. 

  • Excessive lines or spaces in email signatures: Having too many lines or spaces can also push your signature over the character limit.

How to fix the Gmail signature too long error message 

Fixing the signature is too long error in Gmail is a relatively simple process. Just follow these steps: 

1. Check character count  

If you're not sure how many characters your signature has, you can use a character counter tool to check. This will give you an exact number so you can see if it's exceeding the limit. 

2. Trim excess content 

Remove any non-essential contact details. Keep your signature concise and focused on critical information like your name, title, and contact details. 

3. Avoid creating a signature with MS Word  

Microsoft Word is notorious for introducing hidden formatting issues. Instead, use a plain text editor like Notepad or TextEdit. 

4. Optimize image size 

If you're using an image or logo in your signature, make sure it's optimized for the web. Use a tool like TinyPNG to reduce its size without sacrificing quality. 

5. Use simple formatting 

Keep your signature clean and straightforward by using basic formatting instead of multiple font sizes and colors. 

6. Remove spaces between elements 

Delete any unnecessary spaces between elements in your signature, such as extra line breaks or indentation. 

7. Use plain text 

Switch to plain text instead of rich formatting. This reduces character usage and ensures better compatibility across email clients. 

8. Link to external content 

If you need to provide more information, include links to an external page like your social media profiles or company website. 

9. Use URL shorteners 

If your signature contains long URLs, consider using a URL shortener to save space. Bitly and TinyURL are popular options. 

10. Test before sending 

Before sending an email with your signature, make sure to test it by sending a draft to yourself or a colleague. This allows you to catch any issues before they reach the recipient's inbox.
