A shooter, which is a type of shot, does not have a single, universally defined size. However, in the United States, the commonly accepted standard volume for a shot or shooter is 1.5 US fluid ounces (approximately 44 ml). This is the measurement that is most frequently used in bars and is even legally defined in some states.
While 1.5 ounces is the standard, the actual amount can vary depending on the specific establishment. Some bars may pour smaller shots of 1 ounce, which is sometimes referred to as a "pony shot," or they might use a measure of 1.25 ounces.
Internationally, the volume of a shot glass can differ significantly from country to country, with no official global standard. Therefore, while you can generally expect a shooter to be 1.5 fluid ounces in the U.S., the precise measurement is not absolute and can be subject to local custom or a bar's specific pouring .
