In this post I am going to explain how to get logo height, width, image url and alt text in Magento 2.

1. Using Dependency Injection

Add below code snippet in Block class.

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 width
public function getLogoWidth()
{    
	return $this->_logo->getLogoWidth();
}

// Get logo image height
public function getLogoHeight()
{    
	return $this->_logo->getLogoHeight();
}

// Get logo image url
public function getLogoImageUrl()
{    
	return $this->_logo->getLogoSrc();
}

// Get logo image alt text
public function getLogoAltText()
{    
	return $this->_logo->getLogoAlt();
}

 

Add below code snippet in template file.

// Get logo image width
echo $block->getLogoWidth() . '<br />';

// Get logo image height
echo $block->getLogoHeight() . '<br />';

// Get logo image url
echo $block->getLogoImageUrl() . '<br />';

// Get logo image alt text
echo $block->getLogoAltText() . '<br />';

 

2. Using Object Manager

$objectManager =  \Magento\Framework\App\ObjectManager::getInstance();        
 
$logo = $objectManager->get('\Magento\Theme\Block\Html\Header\Logo');

// Get logo image width
echo $logo->getLogoWidth() . '<br />';

// Get logo image height
echo $logo->getLogoHeight() . '<br />';

// Get logo image url
echo $logo->getLogoSrc() . '<br />';

// Get logo image alt text
echo $logo->getLogoAlt() . '<br />';

Thats it. Enjoy Magento 2!!
