Many WooCommerce stores don’t sell products with a fixed price.
Instead, the final cost depends on the size the customer orders.
Whether you sell fabric by the metre, flooring by the square metre, timber by length or custom-made products, customers expect to enter their measurements and receive an instant price.
In this guide, we’ll show you how to calculate product costs by size in WooCommerce and automate the entire process.
Why Calculate Product Cost by Size?
Selling by size allows customers to purchase exactly what they need while ensuring your pricing remains accurate.
This approach is commonly used for:
- Flooring
- Carpet
- Fabric
- Wallpaper
- Artificial grass
- Timber
- Steel beams
- Cladding
- Roofing materials
- Concrete
- Gravel
- Topsoil
- Ribbon and trimming
Rather than creating hundreds of product variations, customers simply enter their measurements and WooCommerce calculates the correct price automatically.
Common Pricing Methods
Different businesses calculate prices in different ways.
Some of the most common methods include:
Area Pricing
Perfect for:
- Flooring
- Tiles
- Wallpaper
- Artificial grass
Formula:
Length × Width × Price per Unit
Length Pricing
Ideal for:
- Timber
- Ribbon
- Fabric
- Fencing
- Steel
Formula:
Length × Price per Unit
Volume Pricing
Commonly used for:
- Concrete
- Gravel
- Topsoil
- Screed

Custom Formula Pricing
Some businesses need more advanced calculations that include:
- Waste percentages
- Minimum charges
- Fixed setup costs
- Multiple dimensions
- Custom mathematical formulas
Can WooCommerce Calculate Product Cost by Size?
Not by default.
WooCommerce can sell products with fixed prices or variations, but it doesn’t calculate prices using customer-entered measurements.
Without additional functionality, store owners often have to:
- Calculate prices manually
- Request quotations
- Create thousands of variations
- Develop custom code
For businesses selling made-to-measure products, this quickly becomes difficult to manage.
