Built to Solve Our Own Shipping & Excel Headaches
We were a small e-commerce team tired of juggling clunky spreadsheets just to ship a few pallets. So we wrote a simple web tool for ourselves—and decided to share it for free.
How It Started
A while back, we ran a small e-commerce brand. Whenever we had to ship pallets out to our 3PL warehouse or retail partners, we were doing what almost every small shipper does: wrestling with an Excel spreadsheet.
Every shipment required calculating cargo volume, estimating pallet stacking patterns, figuring out the freight class, and checking how many linear feet the pallets would take on a trailer. In Excel, this meant copying and pasting the exact same carton dimensions and weights across multiple tabs. Formulas would break, numbers would get mistyped, and looking up NMFC density charts was slow.
We looked around for existing tools, but found that most calculators were completely disconnected: one site only calculated density, another only did box stacking, and none of them shared data with each other. Meanwhile, enterprise logistics software was far too complex and heavyweight for quick day-to-day checks.
Solving Our Own Problem
So we decided to build what we wished we had: a fast, lightweight web calculator where you enter your cargo dimensions once, and the numbers automatically carry over between Freight Density, Freight Class, Pallet Stacking, and Trailer Linear Feet.
Once it was working and saved us hours of repetitive typing each week, we figured other small e-commerce sellers, warehouse clerks, and dispatchers probably faced the exact same frustration. We decided to put it online so anyone could use it freely.
Our Core Principles
✓ No Registration Required
No account creation or mandatory onboarding. Just open the page, type your numbers, and get instant results.
✓ Enter Data Once
Enter handling-unit dimensions once, and seamlessly toggle between density, class, pallet stacking, and linear feet.
✓ 100% Client-Side Privacy
Calculations run locally in your browser. Your carton sizes, weights, and product specs are never stored on our servers.
✓ Built for Everyday Operations
Free and practical for anyone shipping pallets or quoting freight. If it saves you a few minutes during dispatch, that is all we could ask for.
