UNHCR – Warehouse space standards

The size of warehouse required for an operation is determined by the maximum quantity of supplies, in tonnage and volume, that will be stored there at any one time. This quantity is determined by calculating the number of persons of concern, the lead-time needed to replenish the warehouse, the type of distribution system in use, the frequency of distributions (monthly, weekly, etc.), and the nature of the support items that persons of concern need.
