WooCommerce Max Quantity


WooCommerce Max Quantity is a simple extension for WooCommerce that only does one thing: it lets you set a max limit for the number of items that can be added to the cart, for each product, per order.

It’s like one of those signs at the grocery store that says, “LIMIT 2 PER CUSTOMER!” This plugin will not add a sign like that, but the quantity input field (pictured above) will hit a limit.

You can simply set a universal limit to affect all products in your WooCommerce store. If you prefer, you can set a different limit for each product, individually. Each product’s own limit will always override the universal limit. (Support for setting different limits per product was added in WooCommerce Max Quantity version 1.4.)

This works for all products in your WooCommerce store: Simple and Variable products. (Support for products with variations was added in version 1.4.)

Customers do not have to be logged in for this to work. This works for guest buyers, as well as logged-in buyers.

See the setup instructions and documentation.

Includes .mo and .po translations for Dutch (thanks to Martijn Heesters), French, German (thanks @tofuSCHNITZEL), Hindi, and Spanish languages. Also includes a .pot file to make more translations.


  • The universal max setting. It is labeled, “Maximum Quantity Limit Per Product.” It is found at WooCommerce -> Settings -> Products tab -> "Inventory" link

  • An individual product’s “Max Quantity Per Order” setting. It is found on the individual product page, in the Product Data box, on the Inventory tab.


Install and Activate

  1. In your WordPress dashboard, go to Plugins –> Add New.
  2. Search for “WooCommerce Max Quantity” to find the plugin.
  3. When you see “WooCommerce Max Quantity”, click “Install Now” to install the plugin.
  4. Click “Activate” to activate the plugin.


The plugin only has 2 settings. You can use these settings in a variety of ways to accomplish the unique goals of your store. See the documentation for specific ways to use these settings:

  1. To set a universal limit to affect all products, go to WooCommerce -> Settings -> Products tab. Click “Inventory”. Scroll down to “Maximum Quantity Limit Per Product”. Set your desired limit there.
  2. To set an individual product limit for a single product, go the product’s own “Edit product” page. Scroll down to the “Product Data” box. Click on the Inventory tab. There, you’ll see the setting called, “Max Quantity Per Order.” Set your desired max limit for that product, there.


Does this plugin work with products with variations (Variable products)?

Yes, since version 1.4.

Can I set a different limit for different products?

Yes, since version 1.4.


Works great!

Since version 1.4 each product has its own max quantity.
The only missing thing is that each product should have been assigned the global max limit (defined in versions <= 1.3) when upgrading.


I ignored that this plug-in is untested with my version of WordPress and downloaded it and it ended up being very buggy. When I tried to uninstall the plugin, some features remained. I had to manually delete all of the files for my site to be clean and so I could start over with another plugin.

Don’t download this plugin unless it’s been updated.
