A standard shot glass typically holds 1.25–1.5 US fl oz (37–44 ml), although there is no single official size in most places.
Understanding Standard Shot Glass Sizes
While often used interchangeably, the capacity of a "shot" can vary depending on location and local regulations. Unlike other measurements in bartending, there isn't a universally mandated standard size for a single shot glass.
Shot Sizes in the United States
In the United States, the concept of a "standard" shot size varies. According to available information:
- There is no official size for a single shot recognized nationwide.
- In Utah, a shot is legally defined as 1.5 US fl oz (44.4 ml).
- Elsewhere in the U.S., the generally accepted standard size for a single shot is considered to be between 1.25–1.5 US fl oz (37–44 ml).
This means that a shot pour might be slightly smaller or larger depending on where you are, but it will generally fall within this range.

To visualize the common sizes, refer to the table below:
