Despite its popularity and ubiquity, there is no standard measurement for a shot in America. Because of this there can be some confusion as to how to measure a shot correctly. It should be noted, however, that since there is no set standard, there is also no ironclad correct way to measure out a proper shot. Instead, there are some handy ways to measure what are most commonly referred to as "single" and "double" shots.

Skill level:

Things you need

  • Common shot glass
  • Wide shot glass
  • Double shot glass

  1. 1

    Pour liquor into a common shot glass. The average shot glass holds 1.5 fl oz, and the American "shot" falls somewhere between 1.25 and 2 fl. Oz, most commonly being measured as 1.5 fl. Oz. Many glasses will have a ring near the top of the glass, generally about an eighth of an inch below the lip. Filling the glass to this line will fill the common shot glass to about 1.45 fl. Oz--in-between the two most common measurements. If you wish, you can fill the glass halfway between the lip and the middle of the glass to achieve the lower approximation of a shot: 1.25 fl. oz.

  2. 2

    Pour liquor into a wide mouthed, bar-style shot glass. These glasses hold 2 fl. Oz, instead of the more common 1.5. This measurement is on the high side of the national average, and the glasses are generally not filled to the lip. Again, filling the glass to one eighth of an inch below is standard. This allows room for the liquid to move without immediately spilling when being tipped back.

  3. 3

    Pour liquor into a double shot-glass. The double glasses are generally taller and thinner, with a smaller lip than the traditional shot glass. Again, because there is no set standard for what constitutes a "shot," the double tends to vary between 2.5 and 3 fl. Oz. Some come in 113gr sizes though those are not as common. Properly filled doubles will reach to between one eighth and one 16th of an inch below the lip.

Tips and warnings

  • If you do not have actual shot glasses, use a measuring glass to approximate the shot size. A single generally falls between 1.25 and 1.5 fl. Oz (sometimes going as high as 2 fl. Oz), and a double generally falls between 2.5 and 3 fl. Oz (sometimes going as high as 4).
