The new size will be available only for iced coffee, iced tea and iced tea lemonade drinks in the United States. The Trenta is 7 ounces larger than Starbucks' "Venti" cup for iced drinks, which currently is its largest size on offer.
Drinks in the Trenta size will cost 50 cents more than similar Venti-sized iced drinks, the company said.
Seattle-based Starbucks tested the new size in several U.S. markets last year, saying it was responding to customer demand for larger cold beverages.
The Trenta size will debut in 14 states, including Virginia, Georgia, Florida, Texas, Hawaii and Arizona, on Jan. 18 and in California on Feb. 1.
The world's biggest coffee chain said unsweetened drinks in the new size will have fewer than 90 calories and that sweetened versions will have less than 230 calories.
