Ceramic rectangular-grid shelf packing calculator

Calculate feasible pieces per shelf and chosen grid orientation with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use feasible pieces per shelf and chosen grid orientation to compare changes to your inputs. The method and limits below explain the scope.

Examples

Calculation method

Calculation method

Feasible pieces per shelf

Best of two uniform rectangular grid orientations; no mixed-orientation optimization.

Chosen grid orientation

Compare unrotated and rotated homogeneous grids.

Assumptions & limits

Assumptions & limits

  • Shelf dimensions, ware footprints, supplied clearances. Returns Feasible load arrangement. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Shelf usable width (cm): minimum 1e-12, maximum 1000000000000.0. Shelf usable depth (cm): minimum 1e-12, maximum 1000000000000.0. Identical rectangular ware width (cm): minimum 1e-12, maximum 1000000000000.0. Ware depth (cm): minimum 1e-12, maximum 1000000000000.0. Supplied gap between pieces (cm): minimum 0, maximum 1000000000000.0.
