How to price products by measurement in WooCommerce

Decide whether customers will choose from fixed sizes or enter their own measurements. Fixed options such as 1 metre, 2 metres, and 3 metres can be managed as product variations. Custom dimensions such as length × width need a calculator that converts the input into a quantity and price.

Write down the pricing unit first, such as price per metre, square metre, cubic metre, kilogram, or box. Also decide the minimum order, maximum order, decimal precision, rounding rule, and whether the product is sold in packs.

For a small range of known sizes, create a variable product with an attribute such as size or area. Add each allowed value as a variation and give each variation its own price and stock setting.

This is the manual route and it is fine when the choices are limited. It does not calculate an arbitrary measurement typed by the customer, though, and a large list of sizes becomes difficult to maintain. Do not use a text field or a product attribute alone and expect WooCommerce to change the price.

For custom measurements, install a WooCommerce measurement price calculator plugin, then activate it from Plugins in WordPress. The exact menu names vary between extensions, but the calculator is normally enabled while editing the product in the WooCommerce product data panel.

WooCommerce’s own calculator documentation uses measurement types such as length, area, volume, and weight, with either a direct measurement input or length-and-width fields.

Edit the product and select the measurement type that matches how you sell it. Use a simple area field when the customer already knows the area, or use length × width when the calculator should work out the area. Select the input and pricing units, enter the price per unit, and choose whether to show that unit price on the product page.

For products sold in packs, enter the area, length, weight, or volume represented by one pack. The calculator can then round the required quantity up to enough packs to cover the customer’s requested amount. Keep the input and pricing units consistent where possible because mixed unit systems can introduce small conversion differences.

Set minimum and maximum measurements, allowed increments, minimum price, stock behaviour, and any pricing table ranges. Check what happens below the minimum, above the maximum, and between two pricing bands. A common failure is a product showing the correct figure on the product page but carrying the wrong quantity or price into the cart, so test the cart, checkout, order, tax, and stock records as well.

Also test unit conversions such as feet to metres and confirm the displayed unit label. If the product is sold by box, roll, or sheet, make sure the customer can see both the requested measurement and the number of sellable units charged.

For most stores selling fabric, flooring, sheet material, cable, liquids, or other measured goods, use WooCommerce Measurement Price Calculator. Configure the product’s measurement type, unit price, customer inputs, minimums, maximums, and pack or pricing rules instead of building separate variations for every possible size.

The plugin is designed for customer-entered dimensions and supports length, width, height, area, volume, weight, multiple units, pricing tables, and calculated prices. Verify the calculator output in the cart and checkout before publishing the product.
