Different sizes of Starbucks cups.
The Reason Starbucks Doesn't Call Its Drinks Small, Medium, Or Large

Starbucks doesn't categorize its drinks into the typical small, medium, and large sizes. Instead, the company uses a more distinctive labeling system.

Howard Schultz, former director of retail operations and marketing at Starbucks, visited Italy in 1983 and was inspired by the Italian drink sizes: short, tall, and grande.

The chain now offers six beverage sizes: demi, short, tall, grande, venti, and trenta. Each corresponds to a different liquid measurement for whatever drink you order.

The demi is three ounces; a short is still eight ounces; a tall is 12 ounces; a grande is 16 ounces; a venti is 20 ounces (24 for cold drinks), and a trenta is 30 ounces.

The names that came after the original three are the actual Italian words for the numbers corresponding to the measurements. Venti translates to 20, for example.
