For everyday cooking for three or four people, start by comparing a 4–5 litre round Dutch oven, usually around 24–26cm in the ranges below. Choose the smaller option for modest meals and easier handling, or the larger one if you regularly want leftovers. For one or two people, a 2–3.2 litre pot may be enough; for larger batches, look at 6 litres or more.
The best size depends on what you cook as well as how many people you feed. A soup, a whole roast and a loaf of sourdough use the space differently. Compare the stated capacity in litres, the shape and the overall dimensions before choosing.
Dutch oven size chart: centimetres and litres
These are listed capacities for the Chasseur Classic and Pyrolux Pyrochef round French ovens in our range. The same diameter does not always mean the same capacity. For example, the 20cm Pyrochef holds 2 litres, while the 20cm Chasseur Classic holds 2.5 litres.
| Diameter | Chasseur Classic | Pyrolux Pyrochef | Useful for |
|---|---|---|---|
| 20cm | 2.5L | 2L | Small meals, soups for two and side dishes |
| 22cm | 3.2L | — | Smaller households wanting more room than a 20cm pot |
| 24cm | 4L | 4L | Everyday casseroles, curries and soups |
| 26cm | 5L | 5L | Family meals, leftovers and cooking ahead |
| 28cm | 6.1L | 6L | Larger recipes and batch cooking |
| 32cm | 8.8L | — | Large batches and shared meals, with space and weight checks |
A dash means that size is not listed in our current Pyrochef round French oven range. Capacities are nominal, not a recommendation to fill the pot to the rim. Leave room for stirring, simmering and food expansion. Colour and size availability can change; check the product page.

What size Dutch oven should you choose for your household?
The following are practical starting points, rather than guaranteed serving counts. Appetites, side dishes, bones and the amount of liquid all change how much a pot will serve.
For one or two people: around 2–3.2 litres
A 20cm pot suits smaller portions, rice, soups and side dishes. Consider a 22cm Chasseur Classic at 3.2 litres if you want a little more room. If you cook for two but regularly freeze extra portions, a 4 litre pot may be a better fit than the smallest size.
For three or four people: compare 4 and 5 litres
A 24cm / 4 litre pot is a useful starting point for everyday casseroles, curries and soups. A 26cm / 5 litre pot gives you another litre for larger appetites or leftovers. Choose based on your usual recipe, not just the number of people at the table.
For concrete examples, compare the Chasseur Classic 24cm / 4L with the 26cm / 5L model. The Pyrochef 24cm / 4L in Ocean Blue is another option at the smaller capacity. Follow the links for current prices and specifications.
For five or more, or regular batch cooking: compare 5–6.1 litres and larger
Start with the 26cm and 28cm options, then check the quantity your recipe makes. A 28cm pot offers more room for a big stew or a batch of soup. The 32cm Chasseur Classic holds 8.8 litres, but its size and weight make it a more substantial commitment. Check that you can lift it comfortably and that it fits your oven and storage space.
For whole chickens, shanks or roasts, also check the food's length and width against the pot's usable interior. Litres alone cannot tell you whether a particular cut will fit.
24cm or 26cm Dutch oven: which is more useful?
In the Chasseur Classic and Pyrochef round ranges shown here, the choice is 4 litres versus 5 litres. That is an extra litre of capacity, rather than a change you can judge from the 2cm diameter difference alone.
- Choose 24cm / 4L if you usually cook moderate quantities, have limited storage or want to keep the pot more manageable.
- Choose 26cm / 5L if you often cook ahead, want leftovers or find a 4 litre recipe already fills your current pot.
Compare the exact models' empty weights and handle-to-handle dimensions. Food and liquid add to the lifting weight. A pot that suits your routine and is comfortable to handle is more useful than extra capacity you rarely need.
What size Dutch oven do you need for sourdough bread, in litres?
A round pot of roughly 4–5 litres is a useful starting point for a single round sourdough loaf. Confirm the pot size against your recipe and shaped dough before buying. A smaller loaf may need less space, while a larger loaf or an oval loaf may need a different capacity or shape.
A lidded pot helps retain moisture released by the dough during baking. But litres are only part of the fit: the usable base width and clearance below the lid matter too. A shallow 4 litre casserole is not interchangeable with a deeper 4 litre French oven.
- Check the recipe's recommended vessel and total dough quantity. Flour weight alone is not the finished dough weight.
- Allow room around and above the shaped loaf for expansion. The diameter printed on the pot is not necessarily its flat internal base diameter.
- Match the shape: a round pot suits a boule; an oval pot may suit a longer loaf.
- Check the pot, lid and knob's permitted temperature and the manufacturer's instructions for the baking method.
Check empty-preheating instructions before using a bread recipe. Many recipes call for a very hot, empty pot. Chasseur advises against heating its cookware empty. Do not use that method in Chasseur cookware. For any other pot, confirm that both its instructions and temperature limit permit the recipe's method; otherwise choose a compatible recipe or a purpose-made bread baker. King Arthur Baking also discusses checking suitability before empty preheating.
Round or oval Dutch oven?
A round French oven is a practical first choice for soups, curries, casseroles and other dishes you stir. Check its base size against your hob's cooking zone.
An oval pot can be helpful for longer cuts and roasts. Compare its internal length and width, and check how its base sits over your cooking zone. If oven cooking is your main use, check the overall length including the handles before choosing.
Do not compare round and oval pots by the centimetre label alone. The Chasseur Classic 27cm oval French oven is listed at 4 litres, the same nominal capacity as its 24cm round French oven, with a different shape.
Five checks before buying a Dutch oven in NZ
- Capacity: match litres to your usual recipes, with space for stirring and expansion.
- Oven fit: check the full width or length including handles, plus height with the lid and knob.
- Weight: consider the empty pot and the added weight of a cooked meal.
- Cooktop fit: check compatibility and base size against your appliance's instructions, especially for induction.
- Care and temperature: check the exact model's instructions, including the lid, knob and any restrictions on empty heating.
Common Dutch oven sizing questions
Is a 4 litre Dutch oven big enough for a family of four?
It can be a useful size for a moderate casserole or curry served with sides. Choose 5 litres or more if you usually cook generous portions, bulky ingredients or extra meals for the freezer. Check the recipe's yield and leave headroom.
How big is a large Dutch oven?
There is no universal size labelled “large”. In the ranges in this guide, the 28cm models hold 6–6.1 litres, while the 32cm Chasseur Classic holds 8.8 litres. Use the stated litres and dimensions to compare products.
Does every 24cm Dutch oven hold 4 litres?
No. Both round ranges shown in our chart list their 24cm French ovens at 4 litres, but capacity varies with the model and depth. A shallow chef pan with the same diameter can hold considerably less.
Is a Dutch oven the same as a French oven?
In this guide, we use Dutch oven for the general lidded cast iron pot and French oven for the enamelled Chasseur and Pyrochef products. Check each product's material, shape and care instructions when comparing them.
