Cargo Fit Planner

Moving day has a way of turning simple geometry into an argument with a sofa. Start by describing the cargo space: a hatchback trunk, folded seats, a wagon, minivan, short or long van, box body, or trailer. If you measured it yourself, enter the three dimensions manually, then add the permitted cargo weight. Build the item list from a catalog with three box sizes and around fifty common objects with realistic dimensions and weight, or add anything missing by hand. For each item, mark whether it can ride on its side or only upright, how fragile it is, whether it can carry weight above it and how much, whether it is soft enough to lie over uneven cargo, and whether you need it immediately after arrival. When the list is ready, the app tests hundreds of packing arrangements and selects the best result by how many items fit, how tightly the space is used, and how evenly weight is distributed. Objects need support beneath them, fragile items cannot carry other cargo, lower items must not be crushed, heavy pieces stay low and closer to the center, and anything needed first remains near the doors. The result appears as a three-dimensional cargo layout you can rotate, zoom, and inspect item by item. Tap anything to see what it is, how much it weighs, and when it should be loaded. Cutaway mode removes upper layers so you can check what sits underneath, while top, side, and door-facing views reveal awkward gaps. The report shows used and remaining volume, kilograms used from the permitted load, the center of gravity vertically, lengthwise, and across the vehicle, plus any left or right imbalance. It can flag excess weight, poor balance, a center of gravity that is too high, or an item that cannot fit in any orientation. You also get a step-by-step loading order, so following the sequence should not force you to pull things back out. Several plans can be compared side by side, for example using your own car for two trips versus renting a van. This is not a cubic-meter calculator or a moving checklist. It works with dimensions, empty gaps, orientation limits, stacking rules, and access order, then turns the packing problem into instructions you can use beside the vehicle.
