Understanding the different bottle sizes and the amount of beer they contain is crucial when purchasing, sharing, or consuming beer.


In this article, we’ll delve into the various types of beer bottles, standard bottle sizes, and the volume measurement used to determine the amount of beer in a bottle. We’ll also explore the factors that can affect the volume of beer in different bottle sizes. Whether you’re a beer enthusiast or just curious about the math behind those bottles, this article will provide you with the essential information you need.


So, if you’re ready to unravel the mystery of how much is in a bottle of beer, let’s dive right in!


Types of Beer Bottles

When it comes to beer bottles, there are several types commonly used in the brewing industry. Each type has its own unique shape, design, and purpose. Let’s take a closer look at some of the most popular types of beer bottles:

  1. Standard Long Neck Bottle: This is the most common type of beer bottle, also known as the American long neck or the industry standard bottle. It features a cylindrical shape with a long neck and a twist-off or pry-off cap. These bottles are typically made of amber-colored glass to protect the beer from sunlight and maintain its freshness.
  2. European Bottle: Popular in European breweries, this bottle has a distinctive shape with sloping shoulders and a shorter neck compared to the standard long neck bottle. European bottles often come with a crown cork closure and are available in various sizes.
  3. Belgian Bottle: Known for their unique and elegant design, Belgian bottles have a curvier shape and often come with a cork and wire cage closure, similar to champagne bottles. These bottles are favored for Belgian-style beers and specialty brews.
  4. Stubbie Bottle: Originating from Australia and New Zealand, stubbie bottles are shorter and wider than standard long neck bottles. They have a nostalgic appeal and are commonly used for craft beers and certain brands in those regions.
  5. Steinie Bottle: The steinie bottle is a variation of the standard long neck bottle that has a slightly shorter and fatter shape. It is often associated with budget-friendly beers and is popular in the United States.

These are just a few examples of the various beer bottle types available. Breweries may choose different bottle designs based on branding, tradition, or target market preferences. Now that we’ve covered the different bottle types, let’s move on to explore the standard sizes of beer bottles.


Standard Bottle Sizes

Beer bottles come in a range of sizes to accommodate different needs and preferences. Understanding the standard bottle sizes can help you make informed decisions when purchasing or serving beer. Here are the most common standard bottle sizes:

  1. 12 oz (355 ml): The 12 oz bottle is the most widely recognized size in the beer industry. It is often used for individual servings and is commonly found in bars, restaurants, and retail stores. This size is equivalent to a standard American can of soda or beer.
  2. 16 oz (473 ml): Also known as a pint, the 16 oz bottle is commonly used for serving draft beer or craft beer. It offers a larger quantity and is favored by beer enthusiasts and those looking for a more substantial pour.
  3. 22 oz (650 ml): The 22 oz bottle, also referred to as a bomber, is often associated with specialty or limited-edition beers. It provides a larger serving size and is great for sharing or savoring a unique brew on special occasions.
  4. 32 oz (946 ml) and 64 oz (1.89 L): These bottle sizes, known as growlers, are commonly used for take-home purchases from breweries or taprooms. Growlers allow beer enthusiasts to enjoy fresh draft beer from the comfort of their homes and are especially popular among the craft beer community.

These sizes represent the standard bottle sizes found in most countries, but it’s important to note that regional or specialty beers may come in unique sizes or packaging. Additionally, it’s worth mentioning that some breweries may opt for non-standard or custom bottle sizes to differentiate their products in the market.


Now that we understand the standard bottle sizes, let’s take a closer look at how the volume of beer in a bottle is measured.


Volume Measurement

The volume of beer in a bottle is typically measured in two ways: fluid ounces (oz) in the United States and milliliters (ml) in most other countries. These measurements determine the amount of liquid the bottle can hold and help consumers compare and understand the quantity of beer they are purchasing or consuming.


In the United States, fluid ounces (oz) are the standard unit of measurement for beer volume. One fluid ounce is equal to approximately 29.5735 milliliters. This measurement is commonly used on beer bottles, cans, and in bar menus to indicate the amount of beer you will receive.


Outside of the United States, most countries use milliliters (ml) as the primary unit of measurement for beer volume. One milliliter is equivalent to 0.0338 fluid ounces. This measurement is also used on beer bottles, cans, and in most international beer-related discussions.


Both fluid ounces and milliliters serve as reliable measurements to determine the volume of beer in a bottle. By understanding these measurements, you can make more informed decisions when purchasing beer and have a clearer understanding of the quantity you are consuming or serving.


Now that we have a good grasp on volume measurement, let’s explore the amount of beer you can expect in different bottle sizes.


Amount of Beer in Different Bottle Sizes

The amount of beer in a bottle can vary depending on the bottle size and the specific brand or style of beer. Here are some general guidelines for the amount of beer you can expect to find in different bottle sizes:

  1. 12 oz (355 ml) Bottle: A standard 12 oz beer bottle typically contains around 11-12 fluid ounces of beer. This accounts for the headspace, or the gap at the top of the bottle, which allows for carbonation and prevents overflowing when the bottle is opened.
  2. 16 oz (473 ml) Bottle: A 16 oz beer bottle usually contains around 15-16 fluid ounces of beer. Again, the slight variance accounts for the necessary headspace.
  3. 22 oz (650 ml) Bottle: A 22 oz beer bottle typically contains around 20-22 fluid ounces of beer, leaving room for carbonation and an appropriate headspace.
  4. 32 oz (946 ml) Growler: A 32 oz beer growler usually contains around 30-32 fluid ounces of beer. Growlers are typically filled on-demand at breweries, ensuring you get a freshly poured beer.
  5. 64 oz (1.89 L) Growler: A 64 oz beer growler typically contains around 60-64 fluid ounces of beer. This size is perfect for sharing or enjoying multiple servings of your favorite brew.

It’s important to note that these guidelines are approximate and can vary depending on the specific beer style, carbonation levels, and filling techniques. Additionally, some breweries may opt to fill their bottles or growlers to a specific weight or fill line for consistent customer experience.


When purchasing beer, always refer to the label or product description for the specific volume indicated in fluid ounces or milliliters. This will ensure you have an accurate understanding of the amount of beer you’re getting in a particular bottle size.


Now that we know how much beer is typically in different bottle sizes, let’s explore some factors that can affect the volume of beer.


Factors Affecting Beer Volume

Several factors can affect the volume of beer in a bottle, potentially causing variations in the amount of liquid you receive. Here are some of the key factors to consider:

  1. Capping or Sealing: The type of cap or seal used on the bottle can impact the volume of beer. Some closures may leave more headspace, resulting in slightly less liquid in the bottle.
  2. Carbonation Levels: Beers with higher carbonation levels may require more headspace in the bottle to prevent foaming or overflowing upon opening. This can result in a slightly lower volume of liquid.
  3. Sediment or Yeast: Some beer styles, particularly unfiltered or bottle-conditioned beers, may contain sediment or yeast in the bottle. This can reduce the overall liquid volume due to the presence of these additional particles.
  4. Packaging Variations: Different breweries may use slight variations in bottle design or packaging techniques, which can result in small differences in the amount of beer in the bottle.
  5. Fill Line Accuracy: Despite efforts to maintain consistency, human error or variations in automated filling systems can occasionally lead to small discrepancies in fill levels across bottles.

It’s important to keep in mind that these factors usually result in minor variations in the beer volume and are generally within an acceptable range. Breweries strive to provide customers with a consistent and enjoyable experience, ensuring that the amount of beer in a bottle meets industry standards and customer expectations.


If you ever have concerns about the volume of beer in a bottle, it’s best to reach out to the brewery or retailer for clarification. They can provide more specific information about their packaging process and address any queries or discrepancies you may have.


Now that we’ve explored the factors affecting beer volume, let’s summarize what we’ve learned.



Understanding the different bottle sizes and the amount of beer in each bottle is essential for any beer enthusiast or consumer. By having this knowledge, you can make informed decisions when purchasing, sharing, or consuming beer.
