With this feature, you can charge an additional price for specific product sizes. This helps you cover the extra cost that comes with producing larger sizes while keeping your base price fair for all customers.
What is size-based pricing? Size-based pricing lets you add an extra charge on top of your product's base price for specific sizes. For example, if your base price is $20 and you want to charge $22 for XXL, you simply add $2 as the extra price for that size. The customer pays the base price plus the extra amount for the size they choose.
Why does this matter? Larger sizes often cost more to produce. This feature makes sure you are never undercharging for those sizes. It also keeps your pricing transparent and easy to manage, all from one place.
💡 Important Make sure you have already assigned a size set to your product before setting up size-based pricing |
Step 1: Access your store products.
Go to your admin dashboard. Hover over the Products option, then select Create a Custom Product.
Step 2: Find and edit the product.
Locate the product you want to update and click the Edit button next to it.
Step 3: Open the Product Size section.
The Product Size section is located just below the product title. You will see the size set that is currently assigned to your product.
Step 4: Open the Size Set.
Click the Edit Set button next to the assigned size set. A size set window will open, showing all the sizes available in that set.
Step 5: Set the extra price for each size.
In the size set window, you will see an Extra Price field next to each size.
(5.1) Extra Price field — Enter the additional amount you want to charge for that size. This amount will be added on top of the product base price when a customer selects that size.
(5.2) You can set a different extra price for each size or leave it empty for sizes that have no additional charge.
Step 6: Save your changes.
Click the Save button. The extra price will now be applied automatically whenever a customer selects that size during checkout.

🎯 Note You only need to add an extra price for sizes that cost more. Sizes with no extra price will simply use the base product price as usual. |
