What Size Instant Pot Should I Buy?

Let’s talk about Instant Pot sizes!

As we said at the beginning the Instant Pot models come in 4 different sizes: 3, 5, 6, and 8-quart. Although you need to have in mind that not every model comes in all sizes.

Below we review each size so you can understand which is the one that fits your needs, as well the capacity depending on your meals.

3 Quarts Models

instant-pot-sizes-3-quarts-models-pressurecookertips.com

The first capacity is the smaller one with the capacity to handle meals for up to 2 persons, this size is ideal for people that cook for themselves and they usually invite a friend over or for couples.

The Models available in 2019 for the 3-quarts capacity are the LUX, DUO, DUO Plus, and Ultra Series

All the 3 quarts version come with almost the same features that come along with the larger versions, although they have the ability to use less space than the other models making it ideal for small spaces, an RV, o for travels.

These models can be also a great second pot to have, for example in cases that you want to travel with it, so you don’t have to carry your bigger cooker around.

As well in cases like you are already cooking the main recipe on the big pot and you need to cook rice, soups or eggs you have this handy cooker to help you with!.

If you are wondering what happened with the 5 quarts models, is true that there’s a 5-quart DUO model named Duo 50 but at the date has been discontinued. However, the company has made a 5-quart LUX model that’s been available for select retailers like Walmart during Black Friday sales.

6 Quarts Models

This is the most popular model since it fits most types of families and is not as big as the 8 Quarts versions. For families of up to 6 people, this size can handle almost any types of recipes, you can easily fit a whole chicken inside the 6 quarts models making it an ideal choice for most kitchens

As we said already the 6-quart is the only size that comes in every model.  So the LUX, DUO, DUO Plus, Smart Bluetooth, Viva, Nova Plus, Ultra, and Max all came in the 6 quarts size.

This size is so popular because fits most recipes when you are cooking for 4 people, it can handle up to 6 but is perfect when it comes to mid-size families, as well if you are single or just a couple but like to do a lot of meal prep or batch cooking, you can’t go wrong with the 6 quarts version

You can make bigger batches of food in the 6 quarts, and if you have the space for the larger pot, there no better than this model.

8 Quarts Models

instant-pot-sizes-8-quarts-pressurecookertips.com

Now we are talking about the biggest model up to now, is slightly bigger than the 6 quarts version and can handle up to 8 people without any problems.

The 8-quart is available for the LUX, DUO, DUO Plus, and Ultra models.

It’s bigger when it comes to carrying the cooker around as well in terms of space, it will use more space without a doubt, is a big size appliance, but it can get so much food on it that is unbelievable

This size is perfect for large families or for people that cook a lot. As well if you are one of those folks that like to get all the food for the week made in just one big batch this is the cooker for you.

In case you want to cook for more than 4 people any types of food this size is the one to go, if well the 6 quarts version can handle up to 6 people there are lots of types of food that are not fit for the 6 quarts model, on the contrary wit the 8 quarts version there’s no recipe that you can not make for your large family or group of friends.

So the 8 quarts models will use more space in your kitchen and it will take a bit longer to come to pressure compared with the smaller sizes. Although you will have the ability to cook more food on it.

What Instant Pot model series is right for me? 

Instant Pot LUX 6 in 1 (3 – 6 – 8 Quarts)

Instant-Pot-Sizes-lux-6in1-pressurecookertips.com

This model is the best choice for those looking the most budget-friendly Instant Pot. Features 6 appliances in 1 giving you a multifunctional machine with the ability to work as a pressure cooker, a slow cooker, steamer, rice maker, saute and keep warm function as well.

When it comes to size you can get it on 3, 6 and 8 quarts as well! so you have a good range to choose from.

The price difference is due to the lack of the Yogurt function. You may not need to make your own yogurt, although you can also sprout grains and proof bread dough using this function.

Another downside from this model is that there no Low pressure with it, so you can only use high pressure. And last but not least there no lid holders either.

So if you don’t need any of these extra features then the LUX Series it can be the one that fits you the best.

Instant Pot DUO 7 in 1 (3 – 6 – 8 Quarts)

This is the most popular model from the Instant Pot family, was the Best Seller for pressure cookers since 2015 when it was released. Features all the same functions as the LUX model but includes the details that are not included in the 6 in 1 model

One of the biggest improvements to this model is the design of the Pot with a modern and cool LCD touchscreen that will make really easy to understand and use the cooker.

In case you want to know more about it you can check Price and Reviews on Amazon>

Can the size affect the cooking time?

When it comes to the 3 and 6-quart sizes, is always good to add at least one cup of water or any thin liquid such as soda, wine, etc., but nothing thick like BBQ sauce.

For the 8-quart, having in mind that is the largest of the models you should add at least two cups of thin liquid.

Have in mind that adding a thin liquid is important since that is how the steam is going to appear to create pressure.

Is true that there are some ingredients that will release their own thin liquid as you cook them, so you may not need as much liquid. A good example of this is chicken or certain vegetables, like cabbage or onion.

Conclusion

The best size is going to depend on your needs both in the kitchen as well the number of people that you normally are going to be cooking for.

Don’t forget to check the right model as well. You can check Our Instant Pot comparison or reviews for each model in case you need to understand more about each series.

But if you have a medium size family and you don’t need to cook big batches the 6 quarts size is normally the one to go.
