An ideal email banner size is like finding the perfect fit for your shoes.
  

Let me explain.

  
Just as shoes that are too big or too small can be uncomfortable and affect your journey, an email banner that’s too large or too small can disrupt the visual experience of your email and hinder engagement. The right **email banner size** ensures that your message is presented properly, looks great on any device, and enhances the overall user experience, just like a well-fitting pair of shoes makes every step feel effortless.

  

In this guide, we'll discuss what is the ideal banner size to use, best practices to follow and some examples to take inspiration from when designing one.

## What is an email banner?

  

**An email banner is a visual element located at the top of an email, usually within the header section. It often features branding elements like a logo, company name, tagline, and occasionally promotional messages or images.** 

Its main purpose is to capture the recipient's attention, reinforce brand identity, and deliver key information or announcements right from the start.

  

## Types of email banners

  

Email banners are essential for creating effective emails, and they serve different purposes depending on their type. Here are the types of email banners that you'll commonly get to see:

  

![There are 3 types of email banners: Email header banner, email body banner and email footer banner](https://res.cloudinary.com/mailmodo/image/upload/f_auto,q_100/v1725875975/strapi/Types_of_email_banners_c89ee61844.png)

  

### Header banner

  

The [email header](https://www.mailmodo.com/guides/email-header/) banner is the first element recipients see in an email, typically featuring the company logo, the email's main heading, or the key topic. It sets the tone for the rest of the message and is crucial for branding and grabbing attention immediately.

  

### Body banner

  

The email body banner appears within the main content of the email. It is typically used to highlight promotions, key messages, products, or services. It draws attention to important information and engages recipients with the core content of the email or newsletter.

  

### Footer banner

  

The [email footer](https://www.mailmodo.com/guides/email-footer/) banner is located at the end of the email. It often includes contact information, social media links, unsubscribe options, offers, and calls to action (CTAs). Footer banners can also offer compliance with anti-spam laws by providing more detailed sender information and giving your email an organized and professional look.

  

## What is the ideal email banner size?

  

When designing email banners, choosing the right size is essential to make your emails visually appealing, improve your email's functionality, and allow proper rendering across different devices and email services. Some common sizes and guidelines are below to help you get it right:

  

### Email header banner size

![Ideal email header banner size](https://res.cloudinary.com/mailmodo/image/upload/f_auto,q_100/v1725875972/strapi/email_header_size_03d0e536bb.png)

  

- **Desktop:** The width should be between 650px and 700px while the height should range from 90px to 200px. This means that the banner should be 17.19 cm to 18.52 cm wide and 2.38 cm to 5.29 cm high.

- **Mobile:** You can use a width of 350px and a height of up to 100px, that is 9.36 cm wide and upto 2.64 high.

  

### Email body banner size

![Ideal email body banner size](https://res.cloudinary.com/mailmodo/image/upload/f_auto,q_100/v1725875975/strapi/Email_body_banner_size_b200f4ffaf.png)

  

- **Desktop:** The ideal dimensions are 650px to 700px in width and 350px to 500px in height. This means the banner should be 17.19 cm to 18.52 cm wide and 9.26 cm to 13.23 cm high.

- **Mobile:** For smaller screens, aim for a width of 350px and a height of around 200px, that is 9.26 cm wide and 5.29 cm high.

  

### Email footer banner size

![Ideal email footer banner size](https://res.cloudinary.com/mailmodo/image/upload/f_auto,q_100/v1725875975/strapi/Email_footer_size_6ca62b4adf.png)

  

- **Desktop:** The width should be between 650px and 700px, that is, between 17.19 cm and 18.52 cm, with a height of up to 150px, that is, 3.96 cm.

- **Mobile:** A width of 350px and a height of 100px, that is, 9.26 cm wide and 2.64 cm high, works well.

  

### Email signature banner size

  

-   The width should be 650 px, and the height should be between 90px and 150px. This means that the signature banner should be 17.19 cm wide and 2.38 cm to 3.97 cm high.
    

  

### General guidelines for email banner size

  

- **Width:** There’s no one-size-fits-all rule. Your banner width should match the overall width of your email, which typically ranges from 600px to 900px. Popular sizes include 600px, 700px, 800px, and 900px.

- **Mobile considerations:** For mobile, aim for a width of 200px to 320px. Banners should be responsive and adjust to various devices. If the device’s screen size is 100px then it should resize according to that.

- **Height:** Height is flexible and should fit your content needs. Generally, keeping the banner within the first fold of the screen or half of it is best practice. For eCommerce emails, consider extending the height to one and a half or two folds to better showcase products.

## Why does the email banner size matter?

  

Getting the email banner size right is more than just a design choice. It's a crucial factor that directly impacts the effectiveness of your email marketing campaigns. Here’s why:

  

- **Impact on load time:** A large banner can slow down email loading times, especially on mobile devices. This leads to higher [bounce rates](https://www.mailmodo.com/guides/bounce-rate/) as recipients may exit before the email fully loads.

- **Visual appeal and responsiveness:** An improperly sized banner might appear distorted or fail to adapt to different screen sizes, resulting in a poor user experience. A correctly sized banner makes your email look professional and appealing across all devices.

- **Email client compatibility:** Email clients may render banners differently. Choosing the correct size provides better compatibility. This further reduces the risk of your banner appearing incorrectly in certain clients.

- **Engagement and click-through rates:** A well-sized banner with clear, crisp visuals is more likely to grab attention. This leads to higher [engagement](https://www.mailmodo.com/guides/email-engagement/) and click-through rates. Banners that are too small or too large can detract from the message, reducing effectiveness.

## Best practices to create a perfect email banner

  

Designing an effective email banner goes beyond size. It’s about crafting a visual element that grabs attention and drives results. You can follow the best practices to create a perfect email banner given below:

  

### 1. Choose the right dimensions

  

Start by aligning your banner size with the width of your email. Depending on your [email layout](https://www.mailmodo.com/guides/email-design-layout/), common widths are 600px, 700px, and 900px. For mobile devices, ensure the banner scales properly, with widths ranging from 200px to 320px.

  

### 2. Optimize for file size and quality

  

Balance image quality with file size to avoid slow loading times. Aim for file formats like PNG, JPEG and GIF. Keep the file size under 1MB for fast delivery without compromising visual appeal.

  

### 3. Design for visual impact

  

Use high-contrast colors and clear text to make your banner stand out. It should align with your brand’s visual identity and include a clear call to action. A well-designed banner should capture the viewer’s attention and communicate your message effectively.

  

### 4. Test and iterate

  

Before finalizing your banner, test it across different devices and [email clients](https://www.mailmodo.com/guides/email-client/) to check if it displays correctly on the preview. Make adjustments based on feedback and performance to optimize its effectiveness.

## Busting 4 email banner size myths

  

Certain beliefs about email banner sizes can mislead your email design decisions. Let's debunk these common myths to help you create effective and engaging banners for your email campaigns.

  

### Myth 1: Bigger banners lead to better engagement

  

Larger banners don't automatically mean better engagement. While a big banner may catch the eye, it can also slow down loading times and disrupt the email's flow. Instead, focus on a size that fits well within your email design and maintains performance.

  

### Myth 2: One size fits all (debunking the 600px rule)

  

The 600px width rule is not a one-size-fits-all solution. While 600px is a common width, the ideal size for your banner should match your email’s layout and specific design needs. Consider your audience and the content of your email to choose the best dimensions.

  

### Myth 3: Disappearing background colors

  

It is believed that background colors disappear in banners wider than 640px, especially in popular email clients like Gmail and Microsoft Outlook. In reality, many marketers successfully use banners up to 800px wide with their background colors intact. The key is to test your designs across different clients to ensure consistent display.

  

### Myth 4: Banners aren't important for mobile users

  

Ignoring mobile users in banner design is a [major mistake](https://www.mailmodo.com/solutions/avoid-email-template-mistakes/). With [46% of emails](https://blog.hubspot.com/marketing/email-marketing-stats) opened on mobile devices, your banner must be responsive and look great on all screens. Optimize for both desktop and mobile so that your email maintains its visual appeal everywhere.
