How to get Logo url, Image Url, Alt text, Logo size in Magento 2

Logo URL, ALT Text, Image URL, and Logo Size (include height and width) are the basic information you totally get when the logo is applied to your store. In specific, the logo URL is the direct link that will show the page whenever there is any person clicking on the logo.

These elements play an important role in increasing your brand identity and ensuring a good score in SEO ranking. That’s why you will need a perfect size for your logo, a relevant ALT text, and an optimized logo URL. Before that, you need to get all of the existing logo information to easily compare, optimize, update later.

And the logo size is the height and width of the logo image. What about the ALT Text? That is the content which is visible in the logo. Those parameters are open for you to get via this tutorial article if you are running Magento 2 platform on the store.

Step 1: Declare in Mageplaza_HelloWorld

You will use a block class of the module Mageplaza_HelloWorld, then possibly inject the object of Logo class in the constructor of the module’s block class.

app/code/Mageplaza/HelloWorld/Block/HelloWorld.php

<?php
namespace Mageplaza\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
    protected $_logo;    
    
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,
        \Magento\Theme\Block\Html\Header\Logo $logo,
        array $data = []
    )
    {        
        $this->_logo = $logo;
        parent::__construct($context, $data);
    }
    
    /**
     * Get logo image URL
     *
     * @return string
     */
    public function getLogoSrc()
    {    
        return $this->_logo->getLogoSrc();
    }
    
    /**
     * Get logo text
     *
     * @return string
     */
    public function getLogoAlt()
    {    
        return $this->_logo->getLogoAlt();
    }
    
    /**
     * Get logo width
     *
     * @return int
     */
    public function getLogoWidth()
    {    
        return $this->_logo->getLogoWidth();
    }
    
    /**
     * Get logo height
     *
     * @return int
     */
    public function getLogoHeight()
    {    
        return $this->_logo->getLogoHeight();
    }    
}
?>

Step 2: Declare function in template (.phtml) file

Run the below function in your template (.phtml) file

echo $block->getLogoSrc() . '<br />';
echo $block->getLogoAlt() . '<br />';
echo $block->getLogoWidth() . '<br />';
echo $block->getLogoHeight() . '<br />';
