WooCommerce Max Quantity


Requires WooCommerce 3.0 or above.

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.

This works for all products in your WooCommerce store: Simple and Variable products.

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.


I am not affiliated with WooCommerce, WooThemes, or Automattic. I provide this plugin as a free service to the WP community (originally created for my own personal use).


  • 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.

This works like a charm. It let me set a max of 999 units per product for some bulk product boxes.

I really like this plugin, but was experiencing the same frustrations of it not working with variations. I did a little testing...you guys remember there is a global setting as well? It seems that global setting value needs to be set to accommodate the variations. For example, if you have a product with 2 variations and want to limit the number of single order purchases to 2, then set the global value to 4. Get it? If product variations = 5 with single order limit of 2, then set global value to 10. Not ideal, but it works...at least for me.

The plugin does NOT work with variations. At least, I cannot change the max. quantity per variation. One star might be quite rude, but a proper description would have saved me some time for testing. Please, describe the features properly.

Unlike other similar plugins that allow users to try to add MORE than the set maximum quantity to the cart, then come back with a warning error (BAD UX), this simple plugin just disallows the quantity to be set higher than the max in the first place. Thanks Isabel

I tried another plugin, but seemed to cause some issues all of which are resolved by this plugin. I like the link to the cart in the message for too many items. My other plugin didn't have that and it created a bad condition where the user couldn't get back to the cart. Easy to use and very good documentation.
