How much vodka is a drink?

There is no universal standard for the size of a "drink" of vodka. However, some common serving sizes include:

- A mixed drink (such as a vodka tonic or screwdriver) typically contains 1.5 fluid ounces (44 ml) of vodka.

- A shot of vodka is typically 1 fluid ounce (30 ml).

- A double shot of vodka is typically 2 fluid ounces (60 ml).
