How many ounces are in a shot?

Short version: a standard American shot is 1.5 fluid ounces. But "a shot" isn't a legally fixed amount — here's how it breaks down, at home and around the world.

The quick answer
A standard U.S. shot = 1.5 fl oz ≈ 44 ml

At about 40% ABV, that 1.5 oz pour is exactly one U.S. standard drink — the same amount of alcohol as a 12 oz beer or a 5 oz glass of wine.

In the United States there's no federally mandated shot size, so the "right" answer is really a convention: 1.5 ounces is what most bars pour and what nutrition and health guidelines use to define a standard drink. Some bars pour a leaner 1 oz, and a "double" is simply two shots, around 3 oz.

Shot sizes around the world

A "shot" shrinks and grows depending on where you're drinking:

How much alcohol is in a shot?

It depends on two things: the size of the pour and the ABV of the spirit. A standard 1.5 oz shot of 40% spirits holds about 0.6 fl oz of pure alcohol — one standard drink. Bump the proof up (a 50% ABV whiskey) or the pour up (a 2 oz pour) and that climbs quickly.

That's also why one shot roughly equals one beer: the beer is eight times larger, but the shot is eight times stronger, so the alcohol evens out.
