How much mill is a shot glass?

A shot glass is a small glass designed to hold or measure spirits or liquor, which is typically consumed as a single serving. The standard size for a shot glass in the United States is 1.5 ounces or 44 milliliters. However, shot sizes can vary depending on the type of liquor and the desired effect. Understanding shot sizes and how they compare to other drink measurements can help ensure proper pouring and responsible consumption.

Standard US Shot Glass Size

The most common size for a shot glass in the US is 1.5 fluid ounces or 44 milliliters. This is the approximate amount of liquid that the standard shot glass is designed to hold if filled to the brim. The origins of the US standard shot date back to the 19th century, when many distillers sold whiskey in 1.5 fluid ounce portions.

Over time, the 1.5 ounce shot became an informal standard for spirts served in the US. Most shot glasses found in bars and liquor stores in the US are designed to hold 1.5 fluid ounces of liquid if filled completely. So in the US, a standard size shot of alcohol is generally considered to be 1.5 ounces or 44 milliliters.

Other Common Shot Glass Sizes

While 1.5oz is the standard US shot size, shot glasses can vary in their capacity depending on region, alcohol type, or intended use. Some other common shot glass sizes include:

  • 1 ounce or 30mL – A smaller “pony shot”
  • 2 ounces or 60mL – A larger shot sometimes used for certain liquors or cocktails
  • 3 ounces – Used for layered or mixed shots

In some countries, the standard shot size is larger or smaller than the US. For example, a standard shot may be 35ml or 45ml in parts of Europe and Australia. Souvenir shot glasses with novelty shapes may also hold slightly more or less than 1.5oz when filled up.

Comparing Shots to Other Drink Measurements

Understanding how shot sizes compare to other typical drink measurements can be helpful for visualizing pours and consuming responsibly:

Drink Measure Milliliters Ounces
Standard US shot 44mL 1.5oz
Jigger (1.5oz) 44mL 1.5oz
Cup 237mL 8oz
Pint glass 473mL 16oz
Wine bottle (750mL) 750mL 25.4oz
Fifth (750mL) 750mL 25.4oz

As shown, a standard 1.5 ounce shot equates to 44 milliliters. For comparison, a standard cup is 8 ounces or 237mL, so it takes about 5.3 shots to fill a cup. A pint glass holds 16 ounces or 473mL, equal to around 11 shots. And a standard 750mL wine bottle or fifth of liquor contains approximately 25.4 ounces, or 17 shots.

Factors Affecting Shot Sizes

While 1.5oz is considered the standard US shot size, there are some factors that can lead to variance or different sizes:

  • Location/Region – Shot sizes vary globally based on customs and alcohol consumption guidelines. A “shot” in the UK may be 25ml vs. 44ml in the US.
  • Glass Shape – The shape of a shot glass can impact how much liquid it practically holds. Curved or flared glasses may hold more.
  • Alcohol Type – Some establishments may use larger shot glasses for watery mixed drinks vs. a straight liquor shot.
  • Consumption Goals – The desired alcohol effect impacts size. Larger “double” shots are 2-3oz.

So while 1.5oz is a typical shot, the glass used and goals of the drinker impact the exact size and alcohol content. Even “standard” US shot glasses can have some variance around the 44ml mark.

Measuring Shot Amounts

To measure out shot amounts properly, the two main approaches are:

  • Using a jigger – A jigger is a bartender’s tool with two sides for measuring 1oz and 1.5oz pours. Jiggers ensure consistent shot pours.
  • Using a shot glass – Filling up an empty shot glass with liquor and then pouring into a serving glass portions out a standard 1.5oz shot.

For larger “double shots”, measuring with a jigger is important to get the exact increased ounce amount. Counting multiple filled shot glasses can also work for doubles and triples.

Tips for Proper Measurement

  • Use liquid measuring cups for the most accuracy
  • Fill shot glass to the very top for a true 1.5oz shot
  • Use a jigger to portion perfect 1oz and 1.5oz amounts
  • Choose smaller glasses if seeking less than a full shot
  • Opt for larger 2-3oz glasses when desiring a double shot

Using the right drinking vessel and precise measurement tools results in proper shot pours every time.

What is Considered One Drink?

When estimating alcohol consumption, it’s useful to understand what constitutes one alcoholic drink. In the United States, a standard drink is defined as:

  • 12 ounces of beer or cooler – 5% alcohol
  • 8 ounces of malt liquor – 7% alcohol
  • 5 ounces of wine – 12% alcohol
  • 1.5 ounces of distilled spirits – 40% alcohol

So one US standard shot of spirits at 1.5 ounces equates to one alcoholic drink. Beer and wine contain less alcohol per volume, so larger servings are considered a single drink. Understanding standard drink sizes makes it easier to track drinking and follow low-risk alcohol consumption guidelines.

Responsible Serving Sizes

While shot glass sizes vary, some best practices for responsible serving include:

  • Stick to 1-1.5oz shot pours
  • Use jiggers or shot glasses to properly portion each drink
  • Provide water to help pace drinking
  • Allow time between rounds for alcohol to metabolize
  • Offer food to slow absorption
  • Discourage rounds of double or triple shots

Remembering that even 1.5oz shots quickly add up alcoholically can help promote health and safety. Conservatively sized shots lead to a more controlled pace of consumption.

Local Laws and Regulations

In addition to customary sizes, shot pours may be dictated by state or local liquor laws. Some jurisdictions regulate the permitted serving sizes for spirits. Common examples include:

  • Utah – Shot maximum of 1.5oz
  • Oregon – Maximum of 2.5oz per serving
  • California – Single servings up to 1.5oz

Establishments in regulated areas must obey pour limits or risk fines and suspension of their liquor license. Knowing specific area rules ensures legal operation.

Specialty Shot Glass Sizes

While standard shot sizes are 1-1.5oz, certain types of specialty shot glasses are designed to hold larger or smaller amounts. Some examples include:

Double Shot Glass

Holds 2-3oz, for serving oversized mixed shots or extra alcohol

Pony Shot Glass

Holds ~1oz, for a smaller portion of liquor

Cordial Glass

Holds 1-2oz, for serving chilled, concentrated liquors

Test Tube Shot

Creative vial-shaped glasses in varying ounces for novelty shots

The right glassware allows properly portioning different amounts of spirits depending on the occasion and desired strength.

Measuring Alcohol Percentages

Shots contain a higher alcohol percentage than other mixed drinks. Understanding the typical ABV (alcohol by volume) levels can help gauge intoxication rates:

  • Shot of 80 proof liquor – 40% ABV
  • Shot of 90 proof liquor – 45% ABV
  • Shot of 100 proof liquor – 50% ABV
  • Beer – 4-6% ABV
  • Wine – 9-15% ABV
  • Cocktails – 15-30% ABV

While a 1.5oz shot may seem small, its concentrated alcohol content impacts blood alcohol concentration. Alternating shots with lower ABV drinks can help pace intoxication.

Estimating Blood Alcohol Levels

Blood alcohol concentration (BAC) indicates how much alcohol is presently affecting the body. BAC is influenced by:

  • Amount consumed
  • Alcohol proof
  • Time span of drinking
  • Body size and metabolism

As a general guideline, a 100lb person who quickly drinks five 1.5oz shots of 40% liquor may reach near 0.10% BAC. Higher BAC levels impair coordination and cognition. Understanding how shots impact BAC helps inform safe drinking choices.

The Health Effects of Multiple Shots

Due to their concentrated alcohol content, consuming multiple shots in a short timeframe can lead to:

  • Rapid intoxication
  • Impaired judgement and reflexes
  • Decreased coordination
  • Potential alcohol poisoning at high volumes

Excessive shots also increase the risk of alcoholism, liver damage, and certain cancers over time with frequent use. Drinking water between rounds and limiting intake promotes well-being.

Low-Risk Alcohol Consumption Guidelines

To maximize health and safety, the US Dietary Guidelines provide some shot drinking tips:

  • Women: No more than 2 standard drinks per day
  • Men: No more than 3 standard drinks per day
  • Alternate alcoholic drinks with water
  • Do not consume more than 3-4 drinks in 2 hours
  • Avoid shots if pregnant, driving, or taking certain medications

Following these shot drinking guidelines helps reduce health risks and potential alcohol dependency or abuse issues.

Making Responsible Decisions

Some final tips for healthy, moderate shot consumption include:

  • Pace yourself – Sip shots slowly and take breaks
  • Eat food – This helps slow alcohol absorption
  • Set a limit – Decide on a max number of shots
  • Drink water – Prevent dehydration and pace intake
  • Use a designated driver – Don’t risk driving impaired
  • Avoid rounds – Group pressure can lead to excess

Drinking shots responsibly within dietary guidelines allows enjoying flavors without unwanted effects.


In summary, a standard shot equals 1.5 ounces or 44 milliliters of liquor. This amounts to one alcoholic drink. Typical shot glass sizes can range from 1-3 ounces depending on region, alcohol type, or intended use. While shot sizes vary, sticking to 1-1.5oz pours promotes safety and moderation. Understanding shot measurements in relation to serving guidelines and blood alcohol levels is key for making informed, responsible drinking choices.
