Standard size and ounce capacity of mason jars

In the United States, the capacity of mason jars is usually marked in US fluid ounces. Common standard sizes include:

  • Half-Pint 8 oz: Suitable for making small quantities of jams, jellies or as a unmarried dessert container.
  • Pint sixteen oz: This is the most usually used size, appropriate for pickling, storing sauces, and whilst a consuming glass.
  • Quart 32 ounces: A right helper for home canning and dry goods garage, particularly for maintaining huge quantities of food.
  • Half-Gallon sixty four oz: Large capacity design, suitable for storing juice or bulk dry goods.

Of course, there are other special sizes, such as:

  • Mini jars (4 ounces): Often used for gift wrapping or small portions of jam.
  • 12 ounces (Three Quarters Pint): Diamond-patterned jelly jars, cute and practical.
  • 24 ounces (One and a half pints): Flexible choice between pints and quarts.
  • 128 ounces (Gallon): Extra large capacity, suitable for storing large quantities.

These numbers represent the nominal capacity, which is the manufacturer’s recommended fill line, usually located at the “shoulder” position of the jar. This is designed to leave enough headspace to form a good seal during the canning process.

US ounces vs. Imperial ounces: Do you know the difference?

If you come across “ounces” in an international recipe, pay attention – it may be US fluid ounces or Imperial fluid ounces. The conversion between them is as follows:

  • 1 US fluid ounce ≈ 1.04084 imperial fluid ounces.
  • 1 imperial fluid ounce ≈ 0.96076 US fluid ounces.

Although the UK now mostly uses metric units, you may still encounter imperial units in some occasions. Here are the imperial capacities of several common Mason jar sizes:

  • 8 ounces (half pint) ≈ 8.33 imperial ounces.
  • 16 ounces (pint) ≈ 16.65 imperial ounces.

Nominal capacity ≠ actual maximum capacity

Many people wonder: “I clearly filled the entire jar, why does it feel a little more than the nominal capacity?” This is because there’s a concept referred to as overflow capacity, that is the maximum extent of liquid that can be poured to the threshold with out overflowing. For example, a quart jar with a nominal 32 oz may additionally absolutely hold as much as approximately 32.12 ounces of liquid.

This difference is caused by slight manufacturing errors and different jar designs. Different brands and different shapes (wide mouth vs. regular mouth) may be slightly different.

Freezing use? Pay attention to the fill line!

Some Mason jars are designed for freezing. They have a special “freezer fill line” that is generally located about an inch below the thread. This is to reserve space for liquid freezing expansion. Jars with “shoulders” are not suitable for directly freezing liquids unless you leave enough head space.

Size selection suggestions: Which one is best for you?

According to the remarks from most users, pint (16 oz) and quart (32 oz.) are the 2 most famous sizes. The former is suitable for each day use and transportable ingesting water, even as the latter is ideal for domestic canning and long-time period storage. If you like to make jams, puddings or need to offer a small present, half of-pint (eight oz) or 12 oz.Diamond jelly jars also are desirable picks. The huge-mouth mason jars are popular amongst cooking fans due to their larger openings, which can be greater convenient for installing big components or doing away with the contents.

To summarize: how many oz in a mason jar?

  • Half pint = 8 oz
  • Pint = 16 oz
  • Quart = 32 oz
  • Half gallon = 64 oz
  • Gallon = 128 oz

Remember that these are nominal capacities, not the maximum capacity you can pour. When using, you should judge whether you need to reserve headspace according to the purpose, especially when canning, heating or freezing.
