Calculation Desk — Warehouse Capacity Planner

Enter area, clear height, racking type, aisle width and pallet size; see estimated pallet positions, space efficiency, level count and a comparison of 4 racking types. All formulas and assumptions are listed clearly below.

Inputs

Area (m²)Clear height (m)Racking type

Standard selective racking, double rows back-to-back. Direct access to every pallet (100% selectivity), requires wide aisles.

Aisle width (m)Pallet size

Estimated pallet positions

3,120

Space efficiency

%34.7

Level count

Selectivity (access)

%100

4 racking type comparison — same area/clear height/pallet

Racking type	Space efficiency	Level	Selectivity	Total positions
Back-to-Back (Selective)	%34.7	5	%100	3,120
Narrow Aisle (VNA)	%48.6	5	%100	4,365
Drive-In	%50	5	%25	4,495
Push-Back	%42.9	5	%33	3,855

Assumptions used

Column/structural area loss: approx. %5
Level height: 1.5 m (pallet + beam + safety)
Under-ceiling safety clearance: 0.5 m (sprinkler/lighting)
Handling/alignment allowance: +%10
Back-to-back frame clearance: 0.1 m
Narrow aisle (VNA) upper limit: 1.8 m
Drive-in lane depth: 4 pallets (LIFO)
Push-back lane depth: 3 pallets (LIFO)

Warning: This calculation is approximate and comparative; it does not include factors such as structural design, sprinkler/fire regulations, equipment brand/model, floor load capacity or local regulations.
