How Many Jars Do You Need For Canning?

Well, the short answer is all of them. No, I am not exaggerating. When you are gardening to produce food for your family, chances are you would like to preserve some of that harvest for the rest of the year. Or if you are trying to take advantage of a produce sale? Better to have too many jars than not enough. While you can Google recipes all day long, I am more interested in the nitty gritty deals that most people forget to tell you about. Like how many jars do you need for canning? That all depends on your goals.

Before We Jump In

I’ve written a couple posts on canning, so I don’t feel the need to sound like a broken record. But if you haven’t already, check out my post on gearing up for canning season, my homestead buying guide, and my shelving systems. Trust me, you will be glad you did…. at least for the shelves.

Next, we need to ask some questions before we determine how many jars you need for canning. If you are a beginning homesteader or canner, you will need to answer some questions like the ones below.

Are you looking to supply food for the entire year?

If you are looking to supply your family with an entire year of tomato sauce, you need to look very carefully at how much tomato sauce you currently buy or make. For us, we eat spaghetti about once a week. That means I need at a minimum 52 jars of tomato sauce.

The next question is, is that enough? For us, 52 jars would be gone in about six months. Because we also make chili and other things with tomato sauce. Or we will double or triple recipes because we need left overs for work. It’s the same way with green beans, corn, peas, pickles, etc. If I only can enough for what we use, we will be out in no time. That lesson was learned the hard way.

How many people are you feeding?

We are a family of four. But we homeschool and work 24-48 hour shifts. That means that we need left overs. Also we have two growing boys and that means we are also feeding I’m hungry, it’s not mine, and I didn’t do it. So when I am making my projection list for canning, I round WAY up.

What is your skill level with canning?

If you are a novice canner, you need to really consider if you are capable of canning more complex items like soups or stews. It’s not that soups and stews are SO hard to do. It’s actually more of a do you understand the actual process of canning.

For example; if your favorite soup has noodles, do you know that the noodles will turn to mush and become inedible. Same thing with rice, zucchini and other foods that are not as hardy. I’m a advanced but not pro level canner. I still make mistakes. So I know that I need to pay attention or all that hard work will be for not.

Where are you going to put the jars?

I am extremely lucky that I have a full basement. I have sectioned off an entire food storage room. When it’s finished it will have walls, air vents, and a dehumidifier. Jared has also built me these fantastic shelves.

BUT if you don’t have that, you really need to consider how much you can actually can. If you have a tiny pantry, no basement, or other place to put them, you need to get really creative with where stuff will go.

I’ve seen under the bed storage systems for jars that will blow your mind. Keep in mind that your jars should be stored in a cool, dark place. So in a garage that is not temperature controlled probably isn’t the best idea.

Are you buying produce, or are you growing it?

We buy and grow a lot of our produce. Unfortunately, we can’t grow everything we need right now. That’s okay. It’s in the works to grow all the corn we need for a year. But it’s not here yet. If there are financial or garden space constraints, it’s better to identify them now.

Either way, knowing where you are going to source what goes in your jars is another key point in figuring out how many jars you need for canning.

How far away is your local store?

Our local Wal-Mart is about 25 minutes from us. So if I run out of jars, lids, or anything else, I can get to it pretty quickly. The downside is, when it’s canning season in a farming community, there are no jars. You would be lucky to find anything.

Last year, I bought brand new cases of jars because Wal-Mart had no lids! The only way I could get them was to buy the entire set up. Which is fine! I needed more jars anyways.

If your local store is more than an hour away, I would make sure to always have extra jars on hand. Maybe 1 or 2 cases per type of jar.

So how many jars do you need for canning?

I hate to break it to you, but there is no magic formula here. After you answer the questions above, you can get a much better idea for how many you need. BUT I’m not going to leave you hanging. If you are a beginning homesteader and you are trying to figure out a realistic number, I will tell you what I did.

I buy 2 cases per size, per person, per meal.

And yes, it is a TON of jars. Part of my yearly canning list looks something like this:

52 quarts and pints of corn

52 quarts and pints of green beans

104+ quarts of tomato sauce

50 quarts and 25 pints each of: chicken noodle soup base (no noodles), beef stew, enchilada soup, taco soup, beef roast, potato soup, and chili.

25 pints of salsa

25 quarts of pickles

50 quarts each of pinto, black, kidney beans

100+ jars of potatoes

We are a family of 4 and again, we need to have enough for left overs, lunches, if the boys are home alone for the day, etc. This helps to make sure that even if we don’t eat all that corn, we have some for next year.

How many jars do YOU need?

Figuring out how many jars you actually need is going to come down to how much you enjoy canning, your storage, and your finances. Some people can’t afford to drop $12-$20/ person/ meal on jars.

At the end of the day, it’s really about what you can afford. If you can only afford two cases at a time, get them! Trust me, you will use them eventually. As you get more comfortable with canning, or you need to start making your own dog food, thanks Bear, you will appreciate having those extra cans.

Also please for the love of all that is good in this world, pick up lids every single time you see them! Come canning season, they have disappeared! Or you can buy reusable lids like Tattler. PS go to their website, they are a TON cheaper!
