What are the sizes and uses of Mason jars?

Mason jars come in a variety of sizes, but the cool thing about them is that there are only two mouth sizes. This means that a 12-ounce wide-mouth Mason jar has the same lid size as a 32-ounce wide-mouth Mason jar. In this article, we will introduce you to the different sizes and uses of Mason jars, so that you can better store your food.

Regular mouth:

The regular mouth size of a mason jar is the original size. We are all familiar with the shape of Mason jars with standard mouths, so if you want your Mason jars to have the classic look of tapered lids and wide bodies, then go with the standard mouth. The diameter of the standard mouth size is 2.5 inches.

Wide mouth:

Wide mouth mason jars were introduced later and they became a favorite for many people because they were easier to clean as you could put your whole hand inside to scrub better.

People who like canning also tend to like the wide-mouth Mason jars because it is easier for them to put food in the jars without spilling anything. The diameter of the wide mouth size is 3 inches.

4oz (Quarter-Pint) Mason Jars:

The 4 oz Mason jar is the smallest capacity size. It can hold up to half a cup of food or liquid, and due to its compact size, it only comes in a regular mouth option. Its height is 2 ¼ inches and its width is 2 ¾ inches. It often called "jelly jars", they are used to can small amounts of sweet and savory jellies. This cute size is perfect for storing spice mixes, and leftovers, or even trying DIY projects like Mason jarring succulents!
