Magento 2 Logo Resizing Guide + Email Logo Configuration

A logo is one of the first things visitors notice on your Magento 2 store. After installing Magento 2, the first thing you should do is replace the default Magento logo with your own.

A  properly formatted and well-sized logo enhances branding of your store, creates a professional look, as well as ensures a seamless user experience across different devices. This guide will explain how to resize and optimize your Magento 2 logo, ensuring it looks great and performs well on all platforms. We will also talk about email logo configuration.  

Why Logo Size Matters in Magento 2

A poorly sized logo can negatively impact your store’s branding. If a logo is too large, it slows down page load speed, especially on mobile devices. If a logo is too small, it appears pixelated, blurry, and unprofessional when enlarged. The logo format also affects its quality across different screens.

Recommended Logo Sizes:

  • Header: 250×65 pixels (maximum)
  • Email templates: 200×50 pixels
  • Mobile view: 180×45 pixels
  • Favicon: 32×32 pixels
  • Print materials: 300×75 pixels

Choosing the right format:

  • SVG: Best for high-quality, scalable logos.
  • PNG: Ideal for transparent backgrounds.
  • JPG: Works well for solid-color logos.

How to Change Magento 2 Logo Size

There are three main ways to resize your logo in Magento 2:

1. Using the Admin Panel (Beginner-Friendly)

  1. Go to Content > Design > Configuration in the Magento Admin panel.
  2. Click “Edit” for your store view.

  1. Upload your logo and set the size (max: 255×255 px).
  2. Click Save Configuration.
  3. Clear the cache (System > Cache Management or use php bin/magento cache:flush).

2. Using Theme Files (For Developers)

  1. Locate your theme.xml file:
           <theme>
    <title>Your Theme Name</title>
    <parent>Magento/blank</parent>
           </theme>

2. Modify the logo.phtml file:

<img src="<?= $block->getLogoSrc() ?>" width="<?= $block->getLogoWidth() ?>" height="<?= $block->getLogoHeight() ?>" alt="<?= $block->getLogoAlt() ?>" />

3. Deploy changes:
php bin/magento setup:upgrade

    php bin/magento setup:upgrade            
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush          

    3. Using CSS (Quick Customization)

    1. Create a custom CSS file: Edit app/design/frontend/YourVendor/YourTheme/web/css/custom.css and add:
    .logo img {
width: 250px; /* Set your preferred width */

    height: auto; /* Maintain aspect ratio */

    max-height: 65px; /* Optional maximum height */
}

        

    1. Include the CSS file in default_head_blocks.xml:
                    <head>
                  <css src="css/custom.css" />
                </head>          
    1. Modify Layout XML to set dimensions:
       <referenceContainer name="header.logo">
    <arguments>
        <argument name="logo_width" xsi:type="number">250</argument>
        <argument name="logo_height" xsi:type="number">65</argument>
    </arguments>
</referenceContainer>

        4. Clear the cache using: 

    php bin/magento cache:flush

    Pro Tips:

    • Always back up files before editing.
    • Test changes in a development environment.
    • Maintain the aspect ratio to avoid distortion.

    How to Add and Change the Email Logo in Magento 2

    What is the Email Logo?

    The email logo is the image shown in the header and footer of transactional emails. Like your store logo, it helps customers better recognize your brand and builds trust.

    If your emails are going to spam, enable SMTP to improve delivery. Below we will show you how to set up an email logo for your Magento 2 store.

    Choosing the Right Email Logo

    Magento 2 supports JPG, JPEG, GIF, PNG, and SVG formats for email logos. You can also adjust the logo size in the admin panel as discussed earlier.

    Tip: To ensure a clear display on high-resolution screens, upload an image that is three times the required size. If you’re unsure about the size, right-click the logo on your website and inspect the element to check its dimensions.

    Steps to Change the Email Logo in Magento 2

    Method 1: Using Magento Admin Panel

    Step 1: Upload Your Logo

    For Magento 2.0:

    • Go to Stores > Settings > Configuration in the Admin panel.

    For Magento 2.1 or later:

    • Go to Content > Design > Configuration and select your current theme.
    • In the design settings table, click Edit under Action.
    • Scroll to Other Settings and open the Transactional Email section.

    • Click Upload to add your logo file.
    • Add Alt text (alternative text) for the logo.
    • Set Logo Width and Logo Height in pixels (without “px”).
    Step 2: Select Header and Footer Templates

    If you run multiple stores or want a custom email look, select a Header Template and Footer Template from the list.

    Step 3: Save and Apply Changes

    Click Save Config to apply the new email logo.

    Method 2: For Developers (Advanced)

    If you are comfortable with coding, follow this method:

    1. Go to the path:
      app/design/frontend/<Vendor>/<theme>/Magento_Email/web
    2. Add an image file named logo_email.png

    Technical Note:
     Magento defines the default email logo file in:
    vendor/magento/module-email/Model/AbstractTemplate.php
     The file should be named: Magento_Email::logo_email.png

    This method allows you to manage the logo directly in your theme files.
