Compare a Coordinate Packing Plan for 20ft and 40ft Containers

How to Use This Tool

Place box groups into editable container dimensions and compare overflow. Compare deterministic box placement in editable 20ft and 40ft container envelopes, track weight limits, overflow, coordinates, and export plans.

The work this page finishes

A volume percentage cannot show whether repeated cartons cross a wall, exceed payload or produce a usable coordinate plan in one container size but not another. For Container Load Planner, a visible row-by-row result preserves provenance, making a single correction possible without rerunning unrelated records or uploading the batch.

Deterministic workflow

Expand item quantities and apply the same deterministic row-layer placement order to both editable internal envelopes, stopping placement at the supplied payload and geometric limits. For Container Load Planner, input guards stop after 5,000 records or 2 MB, and the report separates fatal input problems from recoverable row warnings.

Why a dedicated interface helps

Review the coordinate export with a freight professional and real loading constraints; use it to compare envelopes, not as a certified stowage plan. For Container Load Planner, deterministic ordering, one-click copying and a downloadable artifact make repeated operational review easier than manually reconstructing a response from prose.

Assumptions

• All dimensions and payload limits are verified user inputs.
• Boxes remain upright and use outer dimensions.
• The sequential row-layer heuristic is intentionally non-optimal.

For Container Load Planner, do not discard the source after export: compare the destination result with it, and remember that local execution cannot secure the surrounding device or browser add-ons.

Limitations and review boundary

It does not optimize rotations, axle distribution, lashing, crush strength, doors, pallets, dangerous goods, legal payload or actual carrier equipment dimensions. For Container Load Planner, user values are never run as script, rendered as markup or fetched as network destinations; the page writes them only into text nodes.

Verification and provenance

On 2026-08-26, the rule and examples were cross-checked with ISO — Freight containers, including a known result, a rejected input and a conflict or duplicate case. The example applies identical cartons to both envelopes and reports placed counts, overflow and the coordinate plan for the smaller adequate option.
