01

Storage position

Usable inside dimensions, all in the same unit.

02

Item and constraints

Use packed dimensions. Weight fields are optional as a pair.

How to use this tool

  1. 01

    Enter the usable internal dimensions—not the outside dimensions—of one bin or shelf position.

  2. 02

    Enter one item’s packed dimensions and optional per-item weight and position load limit.

  3. 03

    Allow rotation if the item may be stored on any face, then calculate and review the selected orientation.

Built for real planning work

  • Validate a proposed bin size before a slotting change
  • Compare packaging changes against shelf capacity
  • Estimate units per pick face for replenishment planning

Assumptions

  • Items are identical rectangular cuboids arranged in a regular grid.
  • Clearance is removed once from each container dimension.
  • Weight capacity is treated as a hard unit limit when both weights are supplied.

Frequently asked questions

Does the calculator rotate the item?

Yes, when rotation is enabled it checks all six axis-aligned orientations and reports the one with the highest practical capacity.

What dimensions should I measure?

Use the smallest clear internal dimensions after accounting for lips, beams, labels, dividers, and other obstructions.

Why is capacity lower than volume divided by item volume?

Whole items must fit along each axis, so leftover strips of space cannot always be used.
