How to get category count in Magento 2?

You can get the total category count for the store in Magento 2 by using the getCount() method.

You can fetch that information from
Magento\Catalog\Api\CategoryManagementInterface.

All you need to do is just create a simple Model class which will help you to retrieve the total number of the category. Code is as per below.

<?php
namespace Magemonkey\CategoryCount\Model;
 
use Magento\Catalog\Api\CategoryManagementInterface;
 
class CategoryCount
{
    /**
     * @var CategoryManagementInterface
     */
    private $categoryManagement;
 
    public function __construct(
        CategoryManagementInterface $categoryManagement
    ) {
        $this->categoryManagement = $categoryManagement;
    }
 
    /**
     * Fetch all Category count
     *
     * @return int
     */
    public function getCategoryCount()
    {
        $categoryCount = $this->categoryManagement->getCount();
 
        return $categoryCount;
    }
}

<?php

namespace Magemonkey\CategoryCount\Model;

use Magento\Catalog\Api\CategoryManagementInterface;

class CategoryCount

{

/**

* @var CategoryManagementInterface

private $categoryManagement;

public function __construct(

CategoryManagementInterface $categoryManagement

) {

$this->categoryManagement = $categoryManagement;

}

/**

* Fetch all Category count

* @return int

public function getCategoryCount()

{

$categoryCount = $this->categoryManagement->getCount();

return $categoryCount;

}

Once you done with the code part, you can call method by using below command,

$categoryCount = $this->getCategoryCount();

That’s it.
