Stop Shipping Air. A 3D container loading calculator

Yes. You get 10 free calculations every month, with up to 500 boxes and one container per calculation. No credit card needed.

No. 3dpack.ing runs in your browser. Open the planner on your computer or tablet, describe your load, and get started.

Yes. Add rules such as “do not stack”, “this way up” or “keep at bottom” to your load description, on every plan. Per-item stacking and weight ceilings are part of Business.

You can share your 3D plan with a link on any plan. Excel import and export, and printable reports, come with a paid plan — see the pricing above.

Yes. The HTTP API accepts a shipment description and returns packing results and a link to the interactive 3D plan. See the integrations page for the typed contract and the MCP server.

Container selection mode tests your items against several box sizes at once. Give it your SKU catalogue with dimensions and it reports the smallest box each order fits in, which is what brings dimensional weight charges and void fill down.

There is a REST API you can call from anything that speaks HTTP. When an order arrives, send the item list and you get a box recommendation and a link to the 3D result back. There are no ready-made storefront plugins today, so this is a small integration on your side rather than an install.

Mark an item as fragile and nothing will be stacked on it — that much is on every plan, including the free one. On Business you can go further and set ceilings per item — “wine bottles, maximum 2 high”, or a weight limit for anything resting on a given box — and the solver treats those as hard constraints too.

Incremental loading adds items to a partly loaded container without starting over, and the drag-and-drop editor lets the plan be rearranged by hand. Anyone with the link sees the current plan.

The 3D view shows where each item goes, colour-coded and numbered in loading order, and the printable report carries the same numbering. Most people find their way around it without being taught.

Import pick lists from Excel or over the API, and set the order items should be loaded in — back to front, bottom to top, or by a priority you assign per item. The plan comes out as step-by-step instructions in that order.

Give it the container types you can actually book and let it pack against all of them. You get the mix, the utilisation of each container and what is left over, so the comparison is made on the real load rather than on cubic metres.

The centre of gravity is drawn in the container as you arrange the load, so you can see the balance point move and catch an arrangement that would sit badly on the axle. Item weights are taken into account when the solver arranges the load in the first place.

Every calculation is saved with its utilisation, total weight and container mix, so you can look back over them and see how full you are actually shipping and where the leftover space keeps appearing.

A JSON REST API over HTTPS. The usual shape is: your system posts the item list, the API returns the packing solution and a link to the 3D view, and your system updates its pick lists. The API documentation carries working examples in JavaScript, Python, C# and Java.

Calls are metered per month against your API plan — 1,000 on Starter, 10,000 on Growth, 50,000 on Scale, and an agreed volume on Enterprise. Beyond that, overage is charged per calculation rather than cutting you off. A single call packs the whole shipment, so one order is one call rather than one per item.

On-premise and private cloud deployment are part of the Enterprise plan, shipped as a container image so your data stays inside your network.

Each calculation carries its own constraints and is saved under its own name, so one client's “electronics on top” and another's loading sequence do not have to live in the same profile. Reports can be printed per calculation.

White-labelling is part of the Enterprise plan: your domain, your logo and your colours, with the infrastructure run by us. Get in touch and we will talk through what you need.

API usage is metered against your account, and calculations are saved with the name you give them, so usage can be attributed to a client at the end of the month. Volume pricing is available — ask.
