3D bin packing calculator
3D bin packing is the problem of arranging irregularly sized items inside a fixed container to minimize wasted space. It's NP-hard — meaning there's no perfect formula. But heuristic algorithms get very close. This calculator runs one for you, instantly.
Enter your items, get an optimized 3D layout
Describe your items in plain English — dimensions, quantities, weights, and constraints. The algorithm finds the best arrangement and shows it as an interactive 3D model. Free to try, no signup for your first calculation.

You provide the items (each with length, width, height, and optionally weight and quantity) and the container or bin dimensions. The algorithm tests thousands of placement sequences and orientations to find an arrangement that maximizes space utilization.
The output is an interactive 3D visualization you can rotate and zoom. It shows each item's position, the overall utilization percentage, and flags any items that didn't fit.
Unlike spreadsheet-based calculators that only divide volume, this tool accounts for actual geometry — items have to physically fit without overlapping, and orientation constraints (this-side-up, no rotation) are respected.
