**The number of shots in 1 liter of vodka depends on how large the shots are.** One liter is equal to just under 34 servings of the smallest shot size, 1 ounce.

A standard shot glass holds 1.5 ounces, and 1 liter provides 22.5 servings of this size. Doubles are 2 ounces, and 1 liter yields nearly 17 full servings at this size. Shot glasses come in many different shapes and sizes, though most have thick bases to prevent breaking. Various shapes can hold the same amount of liquid, despite appearing to be a larger size. Taller shot glasses are best used for shots that involve layering different liquors.
