How Many Pumpkin Seeds Fit in A Mason Jar

This blog is about the number of pumpkin seeds that fit into a mason jar. Specifically, how many will fit when you’re carving a pumpkin and taking out the guts inside. It’s also about how much weight one quart-sized canning jar can hold, excluding fruit. A lot of people are wondering this and I’m here to give you some answers.

Why do we need to know this?

A mason jar has the capacity to hold about 1/2 cup of seeds. For example, a medium-sized pumpkin can produce up to 3 cups of seeds. This means that one medium pumpkin can produce enough seeds to fill one mason jar.

In order to make sure that your pumpkin seeds have enough room to grow and sprout, you need to make sure that you have less than 2/3 of the jar filled with seeds. If you are using large pumpkins, you may need more than 1/2 cup of room for each seedling before planting them in soil.

Pumpkin seeds are a great snack, and they can help you get the protein you need. They’re also very inexpensive, which is another reason to stock up on them when they’re in season. However, if you’ve ever tried to eat a whole bunch of pumpkin seeds at once, then you know that even though each seed is small and individually not that much food, it can be hard to fit enough into your mouth at once. Luckily for us, there’s an easy way to figure out how many seeds fit into a jar.

How much will fit in each type of Mason jar?

Mason jars are great for storing small amounts of food. They’re also a fun way to give away seeds as gifts and make them easy to share. If you’re planning on giving away pumpkin seeds this fall, you may be wondering how many pumpkin seeds will fit in each type of mason jar.

  • How Many Pumpkin Seeds Fit in A Quart Mason Jar?

You can fit about 3 cups of seeds in a quart mason jar. This is enough for one person to enjoy eating all winter long if they eat a handful each day.

  • How Many Pumpkin Seeds Fit in A Half-Gallon Mason Jar?

A half-gallon mason jar holds up to 5 cups of pumpkin seeds. This makes it ideal for sharing with friends or family members who enjoy eating pumpkin seeds as much as you do!

A mason jar has straight Walls


A mason jar has straight walls. This means that the amount of seeds you can fit in a jar is limited by the height of the jar, not its diameter.

The straight sides of a mason jar mean that you can fit more seeds in it than you might think.

For example: If we take the average pumpkin seed (1/2 inch in diameter and 1/4 inch thick), and put it in a mason jar with straight walls of 3 inches in height, we can fit 40 seeds inside.

What size pumpkins should You buy?

A large pumpkin will yield about 25-30 cups of pumpkin puree. A medium pumpkin will yield about 15-20 cups of pumpkin puree. A small pumpkin will yield about 10-12 cups of pumpkin puree.

  • Why is it important to know the size of your pumpkin?

The larger the pumpkin, the longer it takes to cook and soften up. If you are looking for a quick and easy way to make your own homemade canned pumpkin puree, then you should use a smaller sized pumpkin (like sugar pie pumpkins). However if you are looking for a more traditional way to make canned pumpkin puree, then you should use a larger sized pumpkin (like bourbon barrels).

Should you buy organic pumpkin seeds?

If you’ve been to the grocery store lately, you may have seen pumpkin seeds for sale in a large mason jar. They’re usually packaged with other nuts and seeds, and are sometimes called pepitas.

  • Does that mean you should buy them?
  • To find out, we tested two types of pumpkin seeds — organic and non-organic — to see if there’s any difference in taste or nutrition.

Pumpkin seeds are high in fat and protein, but they’re also one of the best sources of zinc and magnesium. The only nutrients they contain that aren’t in high amounts are iron (1 mg) and calcium (37 mg).

What kind of soil should you use to grow your pumpkins?

The best way to grow pumpkins is in a raised bed garden. You can use any type of soil for this, but it is best if you can use composted manure or compost with good drainage.

You can also plant your pumpkin seeds directly in the ground, but it will take longer for them to mature because they will have to go through all the stages of growing before they reach maturity.

What is the best way to grow a pumpkin vine?

The best way to grow a pumpkin vine is by planting seeds directly into the ground where you want your vines to be planted. I have tried starting them indoors before and they never do very well indoors so it is best just to plant them directly in the ground. To plant seeds directly into the ground:

  • Make sure you have prepared your garden bed beforehand so that you know exactly where you want your vines planted (pick an area that gets full sun all day long).
  • Add some compost or fertilizer on top of your garden bed so that there are nutrients in this area before you plant your seeds (this will help promote healthy growth).


If you’re only interested in growing one or two pumpkins, a standard mason jar works well enough. But if you really want to get serious about your pumpkin growing, you’ll need to scale up.
