What Is a Standard Drink? Your Complete Alcohol Standard Drink Chart Guide

Most people who enjoy a beer, a glass of wine, or a cocktail after work have no real idea how much alcohol they’re actually consuming. Glasses, cans, and bottles come in dozens of sizes, and pours vary from one bar to the next. Keeping track of intake becomes nearly impossible without a reliable reference. A standard drink chart cuts through that confusion by defining exactly how much alcohol counts as one drink — regardless of what’s in the glass. All data in this article comes directly from a patient education reference on standard drinks that provides precise equivalents and container counts for every major drink type.

What Is a Standard Drink, Exactly?

In the United States, a standard drink is any beverage containing approximately 14 grams of pure alcohol. That translates to about 0.6 fluid ounces — or roughly 1.2 tablespoons — of pure alcohol. This measure is the basis of what health professionals call the standard alcoholic drink size, and it applies across all drink categories, from beer to wine to spirits.

The key insight is that a standard drink is defined by alcohol content, not by how much liquid is in your glass. A large mug of very light beer and a small pour of fortified wine can contain the exact same amount of alcohol. When people ask how many grams of alcohol in a standard drink, the answer is always about 14 grams — that number stays constant no matter what type of drink you’re holding.

Similarly, when it comes to how many ounces of alcohol in a standard drink, the answer is 0.6 fluid ounces of pure alcohol — though the total volume of the drink itself will differ significantly depending on the beverage type.

The Alcohol Standard Drink Chart: Every Drink Type Broken Down

The standard drinks chart below shows exactly how much of each common beverage equals one standard drink. These figures are approximate, since different brands and product types vary in their actual alcohol content.

Drink Type Volume per Standard Drink Examples
Regular Beer or Cooler 12 oz. Standard can, bottle, or draft
Malt Liquor 8–9 oz. Higher alcohol than regular beer
Table Wine 5 oz. Red, white, rosé
Fortified Wine 3–4 oz. Sherry, port
Cordial, Liqueur, or Aperitif 2–3 oz. Baileys, Amaretto, Campari
Brandy 1.5 oz. A single jigger
80-Proof Spirits 1.5 oz. Gin, vodka, whiskey, rum — a single jigger

The pattern in this standard drink chart is straightforward: the higher the alcohol content of the beverage, the smaller the volume that equals one standard drink. A 12-oz. beer and a 1.5-oz. shot of whiskey both deliver the same amount of pure alcohol to your body.

Beer: Standard Drink of Beer and Container Counts

The standard drink of beer is 12 oz. of regular beer or a cooler — the familiar size of a standard can or longneck bottle. When it comes to standard beer oz, 12 is the number to remember. That said, how many ounces of beer is a standard drink depends on the type: regular beer and malt liquor follow different rules.

Malt liquor is significantly stronger than regular beer, so a standard drink of malt liquor is only 8 to 9 oz. A full 12-oz. can of malt liquor actually contains about 1.5 standard drinks — which means many people who drink a single can of malt liquor are already past the one-drink threshold without realizing it.

How Many Standard Drinks Are in Common Beer Container Sizes?

Beer and malt liquor are sold in a range of sizes, and the standard drink count climbs quickly across them.

Container Size Standard Drinks — Regular Beer Standard Drinks — Malt Liquor
12 oz. 1 1.5
16 oz. 1.3 2
22 oz. 2 2.5
40 oz. 3.3 4.5

A 40-oz. bottle of malt liquor — a packaging size commonly available at convenience stores — contains 4.5 standard drinks. Many people treat that entire bottle as one drinking session, which represents a significant underestimation of actual alcohol consumed.

Wine: Standard Drink of Wine and Bottle Math

The standard drink of wine is 5 oz. of table wine — which is a fairly modest pour by most restaurant or home standards. A standard 750 mL bottle of table wine holds about 25 oz., which works out to exactly 5 standard drinks per bottle. If two people split a bottle of wine, they’ve each had 2.5 standard drinks.

Fortified wines such as sherry and port are considerably stronger than regular table wine, which brings one standard drink down to just 3 to 4 oz. Cordials, liqueurs, and aperitifs are stronger still, with a standard drink falling in the 2 to 3 oz. range.

Generous pours are common in both restaurants and home settings. A 7- or 8-oz. glass of table wine — which is not unusual — can easily represent 1.4 to 1.6 standard drinks rather than just one.

Spirits: From a Single Shot to a Full Handle

For 80-proof spirits — which includes most common hard liquors like gin, vodka, whiskey, and rum — one standard drink is 1.5 oz. That’s a single jigger. So when people ask how many ounces of liquor in a standard drink, the answer is 1.5 oz. The same standard drink size of 1.5 oz. also applies to brandy.

How Many Standard Drinks in Larger Bottles of Spirits?

Spirits are sold in a variety of bottle sizes, and the standard drink count climbs fast. Here’s what the numbers look like for 80-proof liquor:

Bottle Size Total Volume Standard Drinks
Pint 16 oz. 11
Fifth (750 mL) 25 oz. 17
Handle (1.75 L) 59 oz. 39

How many drinks in a pint of liquor? Eleven. A 16-oz. pint of 80-proof spirits contains 11 standard drinks — far more than most people would guess from looking at the bottle.

For those wondering how many standard drinks in a fifth of 80-proof spirits, a 750 mL bottle contains 17. Since every standard drink equals 1.5 oz., this also helps answer the related question of how many 1.5 oz in 750 ml: roughly 16 to 17 pours, which lines up precisely with the 17 standard drinks listed for a fifth. How many standard drinks in a pint versus in a fifth is a common point of confusion — 11 and 17, respectively, are the numbers to keep in mind.

How Many Standard Drinks Are in a Mixed Drink?

This is one of the hardest questions in the world of alcohol awareness. How many standard drinks are in a mixed drink? The short answer: at least one, and often significantly more.

A mixed drink made with 80-proof spirits contains one standard drink or more per glass. The range is wide — depending on the type of spirits used and the recipe, a single cocktail can contain anywhere from one to three or more standard drinks. Some cocktails, like a long island iced tea or a strong rum punch, are built from multiple types of spirits and can push well past the two-standard-drink mark in a single serving.

This variability is exactly why cocktails are particularly difficult to track. Home pours are typically more generous than measured bar pours. Some bartenders pour heavy; others follow measured recipes. There’s no single answer to how many standard drinks are in a mixed drink without knowing what went into it — and that’s the point worth remembering.

Quick-Reference: Common Drink Questions Answered

Here are fast answers to the most-searched questions about standard drinks, all based on U.S. standard drink definitions:

Why the Standard Drink Size Matters in Everyday Life

Real-world serving sizes almost never match standard drink sizes. Cans and bottles of beer come in 12, 16, 22, and 40-oz. sizes. A bartender’s pour of wine is often 6 or 7 oz. rather than 5. A cocktail can be made with one shot or three. Without a reliable reference point, it’s easy for anyone to significantly underestimate how much alcohol they’ve actually consumed.

The standard drink framework gives people a consistent way to measure their intake regardless of what’s in the glass. It’s practical, easy to apply, and based on alcohol content — which is what actually matters to the body. Knowing that a 40-oz. malt liquor contains 4.5 standard drinks, or that a 750 mL bottle of wine contains 5, changes how most people think about their beverages.

Conclusion

A standard drink in the United States always contains about 14 grams of pure alcohol — roughly 0.6 fluid ounces. Whether it arrives in a 12-oz. can of regular beer, a 5-oz. glass of table wine, or a 1.5-oz. shot of whiskey, the alcohol content is the same. The standard drink size is fixed; what changes is the container and what’s in it.

The standard drink chart makes it possible to convert any container size — from a single can to a full handle of spirits — into a meaningful, comparable number. And for cocktails, where the question of how many standard drinks are in a mixed drink rarely has a simple answer, knowing that the range runs from one to three or more is itself a crucial piece of awareness. Use this reference to make sense of any drink, in any size, anywhere.
