Warehouse capacity calculator. A pallet count before the tape measure.

Enter the building length, width and clear height, pick a pallet and a racking type, and get an estimated pallet position count with a plan of how the runs or lanes sit in the footprint. Use it to compare layouts, then have the real number measured.

Estimate your pallet positions.

An order of magnitude figure, not a design. It assumes a rectangular clear span, a single racking type throughout and no obstructions.

Runs of 17 bays, three pallets per bay. Every pallet on the aisle. Lowest capacity, highest flexibility. Assumes 1.7m between beam levels.

What the number assumes.

Every assumption below pushes the estimate up. A measured layout almost always comes in lower, which is why the figure is for comparing layouts, not for signing a lease.

Want to know how the systems differ beyond pallet count? The racking system comparison covers rotation, selectivity and aisle widths for each one.

1.7m between beam levels

Levels = clear height less 0.6m, divided by 1.7m, rounded down. Tall or light loads change this.

No obstructions

No columns, doors, dock levellers, offices, plant, sprinklers or fire routes. Every one of them costs positions.

One system throughout

Real buildings often mix a selective pick area with a dense reserve block.

Standard aisle allowances

3.6m for adjustable racking, 1.8m narrow aisle, 3.2m double deep, 4.0m drive-in face and 4.2m shuttle face.

Three pallets per bay

Bay width is three pallet faces plus 0.4m of clearance. Lanes allow the pallet face plus 0.25m.

No load rating

The estimate says nothing about beam, frame or floor capacity. Those come from the design, never from a calculator.

From an estimate to a measured figure.

The survey replaces every assumption on this page with a measurement: clear height to the real obstruction, column grid, doors, floor condition and your actual truck fleet. You get a CAD layout with a capacity figure for the two strongest options and a priced quotation.

Calculator questions.

It is an order of magnitude figure, not a design. It assumes a rectangular clear span, one racking type throughout, 1.7 metres between beam levels and no obstructions. Real layouts lose positions to doors, columns, sprinkler clearance, cross aisles and fire routes, so a measured survey usually comes in below this figure.

The height to the lowest obstruction above the racking, not the eaves height on the drawings. Haunches, lights, sprinkler heads, ducting and heaters all count. If you are unsure, enter a conservative figure and we will measure it at survey.

Drive-in and shuttle lanes are capped by the building. Lane depth is limited to the width left after the face aisle, so a narrow building gives shorter lanes and fewer pallets per lane. The note under the result tells you when that cap applies.

Yes. A Euro pallet presents an 800mm face instead of 1000mm, so more pallets fit along each run. The depth into the racking stays at 1200mm for both, so the number of runs across the building does not change.
