Instant Pot 10 Quart Models

The 10 Quart Instant Pot was the largest available as of early September 2019. It was easy to overlook because it was not listed with the rest of the series on Amazon.

  • Duo Nova 10 Quart

What size is the largest instant pot?

As of 2021, the 8 quart size is the largest Instant Pot sold by the company. Previously the 10 quart model was the largest but the Duo Nova series was discontinued.

For the 8 quart models you have multiple options to choose from, depending on what you need and how much you want to spend:

  • Duo 8 Quart
  • Duo Plus 8 Quart
  • Ultra 8 Quart (via Amazon)
  • Pro 8 Quart
  • Duo Crisp + Air Fryer
  • Viva 8 Quart (via Walmart)

There were also other 8 quart models previously sold along with the 10 quart. You may still be able to find them online or at a local store.

Instant Pot Ultra quart sizes

The Instant Pot Ultra is available in 3 quart sizes: 3 quart mini, 6 quarts, and 8 quarts. Currently Instant is only selling these models through Amazon, though you may find some inventory at other online or local stores.

Is there a 5 quart Instant Pot?

The 5 quart Instant Pot size was discontinued. It was available as an Instant Pot Lux and Duo. It was replaced by the 6 quart model. You may find them in local second-hand stores and check with the company directly if you have one and need parts for it.

You can now choose from 3 quarts, 6 quarts, and 8 quarts, depending on which fits your need.

Is there a 10 quart Instant Pot?

The 10 quart Duo Nova was discontinued. It was released in early September 2019 and was the only model available at that size. It was difficult to find online because it was not listed with the rest of the series on Amazon originally.

You may still be able to find a 10 quart Instant Pot online or at your local stores, but the inventory is likely limited.

If you need an electric pressure cooker larger than 8 quarts you’ll need to look at other brands. You may also want to consider contacting the company to let them know you would buy a larger Instant Pot. With enough feedback maybe they’ll consider making another 10 quart model.

Choose the Instant Pot Size and model that works for you

Fortunately, there are multiple sizes and models for you to choose from, depending on how many people you usually cook for, how you plan to use it, how much space you have available, and how much you want to spend.

The 6 quart model is the most commonly recommended size to choose as it gives a greater range of flexibility, most recipes are written for the 6 quart, and has a wider range of accessories available.

I personally went with a 3 quart model to start because I have limited kitchen storage space (including in the freezer), and I am generally only cooking for 1.

One thing to note about the smaller 3 quart models, they don’t usually have all of the smart programs available in the larger 6 quart sizes. For example, if you want the Cake Smart Program, you’ll need a 6 or 8 quart Instant Pot.

Choose the best size that works for you. Don’t worry, many people expand their collection of Instant Pots over time. And you usually can cook using more than 1 Instant Pot at the same time.

How to figure out which Instant Pot size you have

Not sure which Instant Pot size you have? Here’s a quick trick to figure that out.

Check the sticker on the back of your Instant Pot. While the print is a little small, it will tell you the model you currently have along with the volume (size) in terms of quarts: 3, 6, 8, or 10. If you have an older model Instant Pot, it’s also possible you have a 5 quart version.

With the 6 quart model being the most popular, it wouldn’t be surprising if you have that one. But it’s always a good idea to double-check if you have any questions.

What are your other questions about Instant Pot sizes?

When shopping for an Instant Pot you have multiple size options available: 3 quart, 6 quart, and 8 quart across different models. As part of deciding which to buy you need to think about your kitchen space, what types of dishes you’ll cook, and how much you want to spend.

The option available will change over time and you’ll likely find a need to own multiple sizes. Smaller side dishes can fit nicely into a 3 quart while the 6 and 8 quart models are great for both main dishes and batch cooking.

What other questions do you have? And what are you considering as part of your research?

Instant Pot Sizes: The Quart Sizes Available By Models


  1. Is there a 6 qt model with a nonstick pot instead of stainless steel? I don’t want to buy a separate insert.

    1. Hey Lexa –

      I don’t think I’ve ever seen that combo. You might find a combo on Amazon. Honestly, if you have the space in your kitchen, the extra liner is a nice thing to have if you’re going to cook a few things back to back. It gives you a little breathing room on either prep and/or cleanup.

      Thanks for stopping by!

  2. I have the Instant Pot 5 quart. I see lots of accessories for 6 and 8 quart. Will any of these work with the 5 quart?

    1. Hi Debbie –

      You’ll need to measure your inner liner to see if any of the 6 quart accessories will work. Since IP hasn’t sold that particular size in a while, I’m not sure how much smaller the width is on the smaller liner. I have seen some accessories advertise that they fit the 5 quart sizes.
