UPS says it will consider box size when setting prices for ground shipment of parcels within the U.S. and Canada.
The move announced Tuesday follows a similar change by rival FedEx.
UPS thinks that the change will push customers to put lightweight items in smaller boxes that take up less space on its familiar brown trucks, reducing the company's costs.
The change takes effect Dec. 29, after the big holiday-season shipping period. UPS already factors box size in rates for air shipments.
