Many businesses sell products by weight rather than by individual items. Whether you’re selling compost, animal feed, powders, metals, coffee beans or bulk food ingredients, customers often need to buy an exact quantity.
WooCommerce doesn’t include dynamic weight-based pricing out of the box, but with the right measurement pricing solution you can automatically calculate prices based on the weight entered by the customer.
In this guide, we’ll show you how to sell products by weight in WooCommerce.
Why Sell Products by Weight?
Weight-based pricing allows customers to purchase exactly the amount they need while keeping your product catalogue simple.
Common examples include:
- Animal feed
- Coffee beans
- Tea
- Flour
- Sugar
- Compost
- Fertiliser
- Sand
- Powders
- Metal offcuts
- Plastic pellets
- Resin powders
Instead of maintaining dozens of product variations, customers simply enter the required weight.
Example Weight Pricing
Suppose your product costs:
£2.75 per kilogramA customer enters:
35 kgWooCommerce calculates:
35 × £2.75 = £96.25The total updates instantly before the customer adds the product to their basket.
Problems with Fixed Product Variations
Many stores create variations such as:
- 1kg
- 5kg
- 10kg
- 20kg
- 25kg
- 50kg
As your product range grows, these become increasingly difficult to manage.
Dynamic pricing allows customers to order custom quantities without creating endless variations.
Automatically Calculate Prices by Weight
With measurement pricing, customers simply enter the weight they require.
WooCommerce then automatically:
- Calculates the total cost
- Updates the price live
- Applies pricing rules
- Displays the final total immediately
No manual quotations or custom calculations are required.
Advanced Pricing Rules
Many businesses also need to include:
- Minimum order values
- Bulk discounts
- Packaging charges
- Delivery fees
- Pallet charges

- Handling fees
These can all be incorporated into your pricing formula automatically.
