Some products aren’t priced by their surface area or length—they’re priced by the total perimeter. This is common for products such as fencing, edging, trim, framing materials and custom manufacturing where the outside boundary determines the cost.
Unfortunately, WooCommerce doesn’t include perimeter pricing by default.
In this guide, we’ll show you how to calculate product prices automatically using perimeter measurements in WooCommerce.
What is Perimeter Pricing?
Perimeter pricing means charging customers based on the total distance around an object.
For example:
- Garden fencing
- Lawn edging
- Decorative trim
- Picture framing
- Rubber seals
- Window beading
- Aluminium edging
- Metal framing
- Protective edging
Instead of charging by area, the price is calculated from the total perimeter entered by the customer.
How Perimeter Pricing Works
Imagine you sell decorative edging at:
£12 per metreA customer enters:
Length: 8m
Width: 5mWooCommerce calculates:
Perimeter = (8 + 5) × 2
= 26 metres
26 × £12 = £312The customer immediately receives an accurate quotation.
Businesses That Benefit
Perimeter pricing is ideal for:
- Fence suppliers
- Garden edging manufacturers
- Frame manufacturers
- Glass suppliers
- Mirror manufacturers
- Rubber seal suppliers
- Aluminium trim suppliers
- Flooring edging retailers
- Landscaping companies
Instead of creating hundreds of product variations, customers simply enter their required dimensions.
Why Manual Quotes Slow Sales
Without perimeter pricing, many businesses rely on:
- Email quotations
- Telephone orders
- Manual calculations
- Custom invoices
- Spreadsheet pricing
This creates delays and increases the chance of pricing errors.
Allowing customers to calculate prices themselves makes ordering much faster.

Modern WooCommerce stores can automatically:
- Calculate perimeter
- Multiply by a price per metre or foot

Common Pricing Rules
Many perimeter-based businesses also require:
- Minimum order values
- Corner charges
- Cutting charges
- Installation costs
- Delivery fees
- Bulk discounts
- Waste allowances
These can all be included within your pricing formula.
