All about increment, and min/ max quantity in WooCommerce

WooCommerce stock, increment, and quantity options

By default, WooCommerce lets you sell products in the standard quantity increment (1). So buyers can add products by integers starting from 1 until they reach the maximum quantity that comes from the product inventory settings. You can set the WooCommerce product stock in the Edit product screen → Inventory.

Setting a minimum or maximum quantity per product isn't just a technical setting — it directly protects your margins and operations. If you sell wholesale items with high packing or shipping costs, a minimum quantity ensures every order stays profitable. On the other hand, a maximum quantity limit is useful during flash sales or limited-stock promotions, where you want to spread inventory across as many customers as possible instead of losing it all to a single bulk buyer. With Flexible Quantity, both limits are configured per product, so you can apply different rules across your catalog without affecting products that don't need them.

But, as you know, that’s all!

So, how to define the minimum and maximum product quantity for WooCommerce products, or set a different quantity increment per product the right way?

✅ Fortunately, there is a free plugin you can use to set the new quantity increment per product and limit the min/ max quantity of the WooCommerce product your customers can buy 😊!

Let’s see now how to use the plugin to limit the quantity per WooCommerce product.

Customize products and quantity settings

Later in the article, you’ll see some examples of new quantity settings for WooCommerce products with new units of measure. But for now, let’s focus on the steps after you’ve installed and activated the Flexible Quantity plugin. If you haven’t done that yet, first download the free plugin to limit the quantity per product in WooCommerce.

1. Change the quantity increment in WooCommerce

To limit the quantity per product and change the increment, first, edit a WooCommerce product, and go to the Product data section. Enable the plugin options in the Flexible Quantity tab.

Of course, you can leave the standard unit of measure e.g. item. Decide about the quantity increment for the WooCommerce product.

That’s it! Your customers will now see the new increment value on the product page 🛒.

2. Set the minimum and maximum quantity

As you've seen above, you can also set the minimum and maximum quantity for the WooCommerce product in the same place. Limit the quantity per this WooCommerce product and update the product.

That will let you customize the quantity of the product customers can choose during shipping in your store.

3. Min/ max quantity in WooCommerce

When to use the minimum or maximum quantity for WooCommerce products?

For example, when you offer highly discounted products to promote your store. In that case, you want to gather as many customers as possible rather than sell everything to one buyer. So the max value will let you limit the maximum quantity per this promotional product in WooCommerce.

On the other hand, there are also scenarios when you sell smaller items, for example, decorative products. You want to set the required minimum quantity because of the transportation, packing, or refund costs. Let’s assume you sell decoration cards, and you want to set the minimum quantity (number of cards) to 10.

You can use Flexible Quantity for that case too 🎉!

Of course, you can define all three parameters (the increment value per WooCommerce product, and min/ max quantity as well). Customers will choose the quantity with the WooCommerce standard plus and minus buttons.

4. Use the decimals for increment and min/ max settings

Sometimes, you would like to let buyers choose decimals for the quantity of WooCommerce products. For example, 1,5 or 0,25, but it’s not possible in WooCommerce by default.

Fortunately, the Flexible Quantity plugin will help you with that as well 😊!

Go to the WooCommerce product Edit screen → Product data section → Flexible Quantity tab. After enabling the plugin options, choose the increment value, and minimum and maximum quantity. This will limit the quantity range per WooCommerce product, and you can also use decimals!

Decimal quantities matter more than they might seem at first glance, especially for stores selling by weight, length, or volume. Forcing customers to round up to the nearest whole unit either shortchanges them or inflates your order value in a way that feels unfair — neither is good for trust. By allowing values like 1.5 kg or 0.25 liters, you let customers order exactly what they need, which reduces cart abandonment from over-ordering and keeps pricing transparent and accurate at checkout.

5. Change the unit of measure in WooCommerce

Last but not least, with the Flexible Quantity – Measurement Price Calculator for WooCommerce plugin you can change the default WooCommerce unit of measure. So, instead of an item, you may now sell WooCommerce products by multiple new units of measure like weight, dimensions, area, and volume!

Of course, the increment and min/ max quantity settings per product will also work for these WooCommerce new units of measurement 🚀!
