Generally speaking, the Instant Pot models can be found in four different sizes: 3 qt, 5 qt, 6 qt, and 8 qt.

Which Size is the best for you? That depends. If you’re just most likely to be cooking on your own, the tiny 3-quart will possibly be enough; on the flip side, you’ll probably intend to choose an 8 qt model if you have family members of six. Along with that, you may want to consider what you wish to prepare with the pot (e.g. Whole chicken vs Chicken wings).

Listed below, we’ll be taking a look at the distinctions between the 8 quart as well as 6-quart designs.

Instant Pot: 8 Quart vs 6 Quart

First things first, let’s go over which versions are available in what size.

  • Duo: Available in 3, 6, and 8 quart
  • Smart: Available in 3, 6, and 8 quart
  • Lux: Available in 3, 6, 8 quart

The Lux is the only model that comes in a 3-quart size.

Ultra: Only available in 6 quart

As you can see, every Instant Pot model except the Ultra, are available both in the 6-quart and also 8-quart sizes.

But what makes

The 6 Quart Instant Pot:

  • It’s the best pick for families that are up to 5 members.
  • Can cook up to 3 cups of rice (i.e. 6 portions).
  • Can cook up to 16 cups of Liquid (e.g. soup).
  • It’s available in the Lux, Duo, Duo Plus, Ultra, and also the Smart model.

The 8 Quart Instant Pot:

  • Best suited for families that have 6 up to 8 members.

Instant Pot 6 qt vs 8 qtWhich size should I Get?

Depending on how many people leave in your household or for how many people you are going to be cooking regularly is the key for the size that suits you the best, both the 6 quarts as well as the 8 quarts Instant Pot are strong candidates.

Generally, if you have a mid-size family (4 to 6), the 6 quart is more than enough (you can even have some room for leftovers). Having said that, it will also depend on the type of recipe that you are going to be cooking.

To be sure which size suits your kitchen the best you 6 quarts or 8 quarts, you can ask your self:

— How many people are normally going to be eating?
— Will I be doing any batch cooking?
— Am I thinking about having leftovers for the next day?
— What sort of recipes will I be making?

Note: Remember, both the 6 and also 8-quart versions cook food at the speed and heat!


The main difference besides the models is the size, but for those looking just in between the 6 quarts and 8 quarts models is more than obvious that you have a bigger family than a 2 person couple, you need to cook big batches every week and you need a reliable partner that is going to be a good match for all your recipes, not just a few.

So when it comes to small families of up to 5 people you can rest assured that the 6 quarts size is going to suit all of your kitchen needs, but its always good to have some extra space for whole chicken recipes, or for when you receive guesses at home you can always get an 8 quarts and be always ready.

In case that your family is bigger than 5 people then an 8 quarts it’s going to be a safer pick, you need to be able to keep some recipes under a line if you have a smaller sized cooker.

So to be sure that you dont need to cook the same recipe twice you can be sure that the 8 quarts will suit your every need. Goes without saying that it’s only 2 quarts bigger than the 6 quarts to it will suit families up to 8 people but no more than that.
