How to Calculate Product Prices by Area, or Volume in Your Store

Ever tried selling carpet, tiles, or even cooking oil online and struggled with how to price it?

You’re not alone. When I first started setting up my WooCommerce store, I realized that flat pricing doesn’t work for everything. If you’re selling something like fabric by the yard, tiles by square foot, or liquids by volume, you need more than just a basic pricing model. You need a flexible, intelligent pricing system.

That’s where the WooCommerce measurement price calculator comes in. This powerful plugin can transform your store into a customizable, customer-friendly, and revenue-optimized platform. In this guide, I’ll walk you through exactly how you can use the WooCommerce price calculator to price products by length, area, volume, or weight.

 What is the WooCommerce Measurement Price Calculator?

Let’s start with the basics.

The WooCommerce measurement price calculator is a plugin that allows you to sell variable-sized products based on customer-defined measurements. Whether your product is sold by the foot, the pound, the square meter, or the liter, this plugin takes the guesswork out of pricing.

The one I personally use—and highly recommend—is the Advance Pricing Calculator for WooCommerce by Extendons. It gives me the flexibility to set prices based on multiple measurement types, manage inventory, and even offer bulk discounts.

Why Use a Measurement-Based Pricing Model?

 Sell More Accurately

If you’re selling fabric, carpet, blinds, liquids, or construction materials, traditional pricing doesn’t cut it. You need a pricing tool that lets customers enter their required measurements and calculates the total price accordingly.

 Improve Customer Experience

Customers want clarity. They want to know exactly what they’re paying for. A WooCommerce price calculator helps them do just that by offering real-time pricing based on their input.

 Increase Average Order Value

Using pricing tables and volume discounts, you can encourage customers to buy more and get better value—boosting your sales and customer satisfaction.

 Core Features of the WooCommerce Price Calculator Plugin

Let’s go deeper into what this plugin offers:

 Pricing by Length

Perfect for:

• Rope

• Wire

• Pipes

• Fabric

Available units: Millimeter, Centimeter, Inch, Foot, Yard, Meter, Kilometer, Mile

Example: You sell rope at $2 per meter. The customer enters 5 meters. The plugin calculates the total price as $10.

 Pricing by Weight

Best for:

• Meat

• Rice

• Sugar

• Oil

Available units: Kilogram, Gram, Ounce, Pound, Tonne

Example: Selling sugar at $1.50 per kg? If someone orders 3kg, the plugin sets the total to $4.50 instantly.

 Pricing by Area (L × W)

Ideal for:

• Blinds

• Carpet

• Wallpaper

• Tiles

Available units: From sq. mm to sq. miles

You can allow two input fields (length and width), and the WooCommerce measurement price calculator computes the area and total price.

Pricing by Square Area

If your product only needs a single measurement input (like just “100 sq. ft”), this type simplifies the form for customers.

 Price Per Box

If you sell items that come in fixed-size boxes (like tiles or panels), you can calculate how many boxes a customer needs based on room size.

 Pricing by Volume (L × W × H)

This is essential for:

• Soil

• Mulch

• Liquid detergents

Volume units include: Cubic liters, gallons, pints, and more.

H3: Price by Surface Area

Useful for items like wrapping paper or coatings where surface application matters.

 Real-World Applications and Use Cases

How to Set It Up (Step-by-Step)

1. Install the Plugin From your WooCommerce dashboard, go to Plugins → Add New → Search “Advance Pricing Calculator by Extendons”.

2. Activate & Configure Choose your preferred measurement type (length, weight, area, volume, etc.)

3. Add Measurement Input Fields Configure what the customer needs to input. Add labels like “Enter Width in Meters”.

4. Set Pricing Rules Use formulas, flat rates, or tiered pricing based on quantity.

5. Test Your Product Page Always test a live preview. Enter random measurements and verify the price updates correctly.

 Boost Your Sales with Volume Discounts

With tiered pricing tables, you can reward customers for bulk purchases. For example:

• Buy 6–10 meters: $9/meter

• Buy 11+ meters: $8/meter

This encourages larger orders and builds long-term customer relationships.
