Warehouse Space Requirement Calculator

Work out warehouse space requirement instantly with clear inputs, formula shown and shareable results.

About Warehouse Space Requirement Calculator

Warehouse sizing starts with pallet positions divided by the number you can stack or rack vertically, which gives ground positions. Multiply by pallet footprint for net storage, then add an aisle and service allowance — typically 40-55% for reach-truck operations — to get gross area.

Formulas

Ground positions

Ground positions = Pallet positions / Stack height

Gross area

Gross m2 = Ground positions x Footprint x (1 + Aisle allowance %)

Worked example

With the default values below, Warehouse Space Requirement Calculator returns Gross warehouse area required of 391.5. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What aisle allowance should I use?

Roughly 30-35% for very narrow aisle with wire guidance, 40-50% for reach trucks and 55-65% for counterbalance forklifts and block stacking.

Does this include docks and offices?

No. Add inbound and outbound staging, dock apron, battery charging, offices and welfare separately.
