Quick answer

Choose a pressure cooker body size that matches your typical meal portions and fits your existing lid. For small households, a 3.5 L / 20 cm body works well; for larger families, an 8.0 L or 12.0 L body with a wider diameter is better.

Capacity vs. Diameter: What Matters More

Capacity tells you how much food you can cook, while diameter determines which lid fits and how much stovetop space you need. Both matter, but if you already own a Kuhn Rikon pressure cooker, the lid compatibility depends on the diameter, not the volume.

A 3.5 L body with 20 cm diameter suits 1-2 people or side dishes. An 8.0 L body with 24 cm or 28 cm diameter works for 4-6 servings. The 12.0 L body with 28 cm diameter handles large batches for meal prep or entertaining.

Replacement vs. Upgrade: Know Your Goal

If your current pot body is damaged or worn, buying the same size replacement is the simplest route. If you want to expand your set, you can add a different size body as long as the diameter matches your existing lid.

Kuhn Rikon DUROMATIC® bodies are sold as spare parts, so you can mix and match within the same series. For example, the DUROMATIC® FORMA 3.5 L body works only with FORMA lids, while DUROMATIC® INOX and HOTEL bodies have their own lid systems.

Decision rules for choosing a pressure cooker body size

  • Match the diameter to your lid: Measure the diameter of your existing pressure cooker lid. The replacement body must have the same diameter (20 cm, 24 cm, or 28 cm) to seal properly. Check your lid's diameter before ordering.
  • Choose capacity by household size: 3.5 L for 1-2 people, 8.0 L for 4-6 people, 12.0 L for 6+ or batch cooking. Larger capacities also mean longer heat-up times.
  • Consider stovetop space: A 28 cm diameter body needs a burner that can accommodate its width. Ensure your stovetop can handle the larger footprint, especially if you use multiple pots. Measure your burner and pot clearance.
  • Series compatibility matters: DUROMATIC® FORMA, INOX, and HOTEL bodies are not interchangeable between series. Always choose a body from the same series as your lid. Confirm your series (FORMA, INOX, or HOTEL) before purchasing.
