A standard shot glass typically holds 1.5 fluid ounces (oz) in the United States. However, this can vary slightly depending on the country or the specific type of shot glass:
- United States: 1.5 oz (44 ml) is the most common size.
- United Kingdom: Usually about 1 oz (25 ml).
- Australia: Often around 1 oz (30 ml).
If you're measuring for a cocktail or recipe, it's safest to assume 1.5 oz for a standard shot glass in the U.S.
