Not to mention that they are also used to serve portions of mini desserts for parties.

In the United States, the average shot glass size holds about 1.48 to 1.5 ounces. However, since there isn’t an “official” standard size for a shot, this can vary. Some shots can be less than an ounce or even amount to 3 ounces depending on the size of the glass and the state you’re in.

Interestingly, Utah is considered the only state that strictly defines a shot as 1.5 oz, requiring bartenders in the area to pour consistent measurements.
