A standard shot size varies by country and context, but commonly:
- In the United States, a standard shot is typically 1.5 fluid ounces, which equals about 44 ml
- In the UK, shots are often 25 ml or 35 ml depending on the establishment
- Other countries have different standards, for example, Russia often uses 50 ml shots, and Japan or Italy may use 60 ml shots
In practice, shot sizes in the US can range from about 30 ml (1 oz) in busy bars to 60 ml (2 oz) in higher-end venues, but 44 ml (1.5 oz) is the legal and most common standard
. Therefore, the most widely accepted standard shot size is approximately 44 ml.
