Math-based estimate vs. full 3D optimization
These calculators intentionally use a simple mathematical model: we treat your cargo as perfectly stackable boxes and calculate how many fit inside the internal footprint and height of the container or trailer. That makes the answer fast, transparent, and easy to understand.
In production, JustLoad.it goes further with a real 3D packing algorithm that considers mixed item sizes, stacking rules, weight distribution, and more. Use these calculators for quick estimates, then upgrade to a full plan when you're ready to generate detailed 3D loading plans.
