What Are the Different Sizes of Milk Containers?

Milk is one of the most common beverages after water and most of the time, it comes in containers of different sizes. Mostly, we drink goat milk, cow milk or sheep milk and they all usually come in containers.

Milk is sold in different sizes in the United States from 128oz all the way to more than 5g. It is also sold in gallons and one gallon contains 3.785 liters of milk. Want to know more about containers? Keep reading.

Are There Different Sizes of Milk Containers?

Yes, there are different types and sizes of milk containers and you can buy them according to your preference. The minimum container you can get usually is 0.8 liters but it obviously varies according to the region.

Also, if you are buying from a local grocery store, you might not find the biggest gallon size and that is why most people don’t even have an idea of how big milk gallons could be because they have only seen gallons of just a couple of liters.

It is quite apparent that the smaller container won’t have a huge quantity of milk so if you want more milk, you need to go for the bigger containers as they have more space as well as more milk for you.

Just make sure that you check the quantity of milk written on the gallon before actually buying it because it is not always what it looks like. Most people buy a big gallon without reading the quantity of milk and they often find the quantity insufficient.

Types of Milk Containers

As we have already said that there are multiple types and sizes of milk containers and they all sell at different prices too. So, let’s get into it and find out what exactly are the sizes of milk containers.

1. One Quartz

This container is the smallest one you can get out there and it weighs about thirty-two ounces. These are also used for preserving milk and even though you don’t get a lot of milk in these, they still serve their purpose.

It is better to buy one quartz container because then you won’t have to use an opened container of milk multiple times. This container has just the right quantity of milk and you can use it all up in one sitting too so no need to store it in the refrigerator.

The neck width of one quartz container usually is 38mm and it also has a pallet pack of 972ea. Also, all the containers have an overflow capacity and with this one, you get the capacity of 961 ml.

2. Half Gallon

The half-gallon container is also pretty common in the United States and it commonly comes in plastic. This container also has a handle that makes it really easy to carry and the handle is placed right beside its opening. It does not take a lot of space in the fridge and during shipping as well which is why most people go for a half-gallon milk container.

Most of the time, the half-gallon container is translucent and white which makes it really easy to determine the level of milk in the container. This container can store sixty-four ounces of milk in it. However, the neck width of both one quartz and the half-gallon container is the same. But, the pallet pack of the half-gallon container is 648ea.

3. One Gallon

This is the container that those people commonly use who like to stock up so they don’t constantly have to go shopping. It has a lot more space to store milk and it has the capacity to store 128 ounces of milk. The pallet pack of one gallon is 128 ea which is perfect for its size.

This container is translucent too which makes it easier for you to stock up as soon as the gallon runs out. Also, the handle for carrying the gallon makes it really easy to carry. The size of this container might be bigger but it does not become a hassle.

Difference Between Glass and Plastic Containers

There are different types in the material of containers too and even though plastic is easier to carry and people have been using it for years, it is not healthy for the environment and that is why people are now switching to glass containers as they are more sustainable. But obviously, glass containers are heavier and more expensive.

Let’s find out some of the differences:

● Taste

We all know that milk that has been sitting in a plastic container develops a very weird taste and you can almost smell the plastic in the milk which obviously is not a great experience for anyone who is already not fond of milk.

Plastic containers don’t retain the authentic taste of milk and you lose its essence but when we talk about glass bottles, the taste of milk stays intact in them. That is because not a lot of chemicals in the glass bottles react with milk like chemicals in plastic containers do.

When you purchase milk in a glass container, know that it is the original taste of milk and nothing has altered the taste. While with a plastic container, you cannot really say much.

● Health

Plastic containers do pose harm to your health as eating and drinking things right out of plastic containers is not healthy for you. There are a lot of health risks involved in using plastic regularly and it is better to avoid it as much as you can.

Glass containers on the other hand are considered safer because they don’t react with the milk nor do they excrete different chemicals in the milk. That is the reason why most people are going for glass containers these days.

● Sustainability

Plastic containers are harmful to the environment and we all know it at this point. But, you can imagine the harm when billions of people use plastic milk gallons daily. You can still do it but at least acknowledge that there are more sustainable options in the market.

For instance, glass containers are a great option for you if you want to move towards more sustainable living. You can recycle the glass containers too and use them for decorative purposes and even if you throw them out, they don’t turn out to be as dangerous as plastic bottles.

● Longevity

Milk in plastic containers becomes hot faster but in a glass container, it remains cold for a longer time. So, it depends upon your preference which one you prefer because most people don’t like cold milk.

Also, the type of containers determines whether the milk will stay fresh for longer or will go bad. As the glass containers keep the milk cold for longer, it does not go bad quickly while the milk in a plastic container could go bad real quick if not put in the refrigerator at the right time.

Other Types of Milk Containers

The sizes and types of milk containers are not just limited to glass and plastic because there are a lot more of them. Let’s find out what those containers are and what type of milk they are used for.

● Churn

A churn is a container used for transporting milk. It is cylinder-shaped and quite tall which means it can fit about 12 gallons of milk. These churns are usually made of steel but now these are also found in aluminum.

Size-wise, churns are quite big so they are not used at homes commonly and are used mainly for transporting huge quantities of milk and people even order home deliveries for milk.

Churns also do not have caps like regular gallons and instead, they have lids made of metal that have holes in them.

What is Quart in Milk?

We usually use Quart to measure the sizes of milk containers and a lot of people don’t really understand the measurements in a quart. This term basically is used to measure liquids like milk.

For example, if you have 1/4th of a gallon, it would be just equal to one quart. If you want to check in ounces, one quart of milk will be 32 ounces. So, it sounds pretty simple, right? But, if you are buying milk in gallons, you don’t need to know about the quart.

If you are buying less quantity of milk for everyday use, then quart measurements can help you a lot and even some containers are also named by their quart and gallon measurements.


The sizes of all milk containers are so different and you would be amazed to know how many types of containers are available in the market because we don’t always pay attention to smaller things like containers even though they are so important and integral.

We have discussed all the milk container sizes there are and you might even find the smaller or bigger ones but that completely depends upon regions and the needs of people. The container sizes discussed here are standard and can be found almost everywhere.
