How to Get size of product image in Magento 2

This topic demonstrates how to get size of product image in Magento 2.

Getting the size of product image is the next topic you also need to know in Magento 2.

Actually, product image size is a good attribute to your site overall performance. It makes your products closer to customers with a real visualization of your products with details. Having beautiful and professional products images helps you easily attracts customers and stand out among different websies.

To show you clearly, I highly recommend the following example which mention how to display as well as get the size (height and width) of the uploaded product.

2 Steps to retrieve the size of product image

Now follow the instruction below to successfully resize a product image in Magento 2.

Step 1: Upload the product

Open your custom module (Mageplaza_HelloWorld), insert object of \Magento\Catalog\Model\ProductRepository 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 $_productRepository;
    protected $_productImageHelper;
    
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,        
        \Magento\Catalog\Model\ProductRepository $productRepository,
        \Magento\Catalog\Helper\Image $productImageHelper,
        array $data = []
    )
    {
        $this->_productRepository = $productRepository;
        $this->_productImageHelper= $productImageHelper;
        parent::__construct($context, $data);
    }
    
    public function getProductById($id)
    {
        return $this->_productRepository->getById($id);
    }
    
    public function getProductBySku($sku)
    {
        return $this->_productRepository->get($sku);
    }
    
    /**
     * Retrieve image width
     *
     * @return int|null
     */
    public function getImageOriginalWidth($product, $imageId, $attributes = [])
    {
        return $this->_productImageHelper->init($product, $imageId, $attributes)->getWidth();
    }
    
    /**
     * Retrieve image height
     *
     * @return int|null
     */
    public function getImageOriginalHeight($product, $imageId, $attributes = [])
    {
        return $this->_productImageHelper->init($product, $imageId, $attributes)->getHeight();
    }    
}
?>

Step 2: Retrieve the size of the product image

It is possible to get and print the height and width of product_small_image, product_base_image and product_thumbnail_image, etc. Please run the below code:

$id = YOUR_PRODUCT_ID;
$sku = 'YOUR_PRODUCT_SKU';
$_product = $block->getProductById($id);
$_product = $block->getProductBySku($sku);
echo $block->getImageOriginalWidth($_product, 'product_small_image') . '<br />'; 
echo $block->getImageOriginalHeight($_product, 'product_small_image') . '<br />';

With LUMA as the default frontend template, you need to open the layout YOUR_MAGENTO_ROOT/vendor/magento/theme-frontend-luma/etc/view.xml, an you can change the height and width for different media images.
