What's the alcohol weight in a shot?

Standard Shot Measurements

In the United States, the standard measurement for a shot is 1.5 ounces ( oz ) or 44 milliliters (mL). However, it can vary depending on the establishment and the type of liquor served.

Alcohol Content in Shots

The alcohol content in a shot typically ranges from 25% to 50% alcohol by volume (ABV). For example, a 1.5-ounce shot of 40% ABV (80 proof) whiskey or vodka contains approximately 0.6 ounces (18 mL) of pure alcohol.

Typical Shot Sizes and ABV

- Gin: 1.25 oz (37.5 mL), 40% ABV
- Rum: 1.5 oz (44 mL), 37.5% ABV
- Tequila: 1.5 oz (44 mL), 40% ABV
- Whiskey: 1.5 oz (44 mL), 40% ABV
- Vodka: 1.5 oz (44 mL), 40% ABV
- Triple sec: 1 oz (30 mL), 40-60% ABV

When to Worry About Alcohol Content

Be aware that shots can quickly add up, especially if you're consuming multiple drinks within a short period. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines moderate drinking as up to one drink per day for women and up to two drinks per day for men.
