Shelf capacity calculator for rectangular packages

Estimate positions across and deep on one clear shelf, with products arranged one unit high.

All retail calculators

Enter your figures, then calculate. Results use only these inputs and are not saved.

Formula and worked example

Floor(shelf width ÷ product width) × floor(shelf depth ÷ product depth).

Illustrative example: a 36 × 15 shelf with 4 × 3 packages fits 9 across and 5 deep, or 45 units one unit high.

Before you use the result

  • Use the same unit for all four dimensions, such as inches or centimeters. Subtract dividers and any required clearance from the shelf measurements first.
  • The tool models identical rectangular packages in a fixed orientation, one unit high. It does not rotate, stack or mix products, and does not model hanging fixtures.
  • Check product height, shelf clearance, weight limits and physical fit separately. A zero total means the package does not fit in at least one direction.
