The Ooni Karu 2 and Karu 16 sit at different points in the Ooni range – the Karu 2 is a compact multi-fuel oven aimed at portability, while the Karu 16 is Ooni’s largest and most capable multi-fuel oven for serious home use. This comparison covers the key differences to help you choose.
Quick Verdict
Buy the Ooni Karu 2 if: you want a portable, versatile multi-fuel oven that’s easy to store and take to different locations, and you primarily cook 12-inch pizzas.
Buy the Ooni Karu 16 if: you want the flexibility of wood or gas fuel, need to cook larger 16-inch pizzas, and prioritise performance over portability.

Pizza Size
The most significant practical difference is cooking capacity. The Karu 2 cooks up to 12-inch pizzas, which is the same size as the original Karu and the Koda 12. This is a genuine 12-inch Neapolitan pizza – a perfectly reasonable size for most people, and large enough for one generous individual portion.
The Karu 16 cooks up to 16-inch pizzas. This is a noticeably larger pizza – closer to the size you’d get in a proper Neapolitan pizzeria. For feeding a family or a group, the ability to cook larger pizzas makes the process significantly more efficient.
If you regularly cook for 4 or more people, the Karu 16’s larger cooking area is a meaningful advantage. If you cook mostly for 1-2 people, the Karu 2 is more than adequate.
Portability
The Karu 2 weighs around 12kg and folds down for transport – the legs fold away and it fits into a carry bag. It’s a realistic option for taking to the park, a friend’s garden, or a camping trip. The Karu 16 weighs around 28kg and is effectively a semi-permanent fixture once set up. You can move it, but it requires two people and some effort. It’s not designed for frequent transport.
Fuel Options
Both ovens run on wood, charcoal, or gas (with the optional gas burner attachment purchased separately). The multi-fuel flexibility is one of the main reasons to choose either Karu oven over the gas-only Koda range.
Wood cooking in the Karu 16 is a more comfortable experience due to the larger firebox. You can use longer pieces of wood and the fire is easier to manage. The Karu 2’s firebox is smaller and requires more frequent, smaller additions of fuel when cooking on wood.
Gas performance is excellent in both ovens. The Ooni gas burner attachment (sold separately, around £60-70) converts either oven to gas in seconds and makes temperature management much more straightforward.
Build and Materials
The Karu 16 uses a thicker cordierite stone and more substantial insulation than the Karu 2. This means it retains heat better between pizzas and is more forgiving if you’re cooking several in succession. The Karu 2’s thinner stone can cool more noticeably if you take too long between pizzas.
Both ovens have viewing windows and chimneys, and both are made from quality powder-coated carbon steel with stainless steel components around the flame area.
Price
The Karu 2 is the more affordable option by a significant margin. The Karu 16 is one of Ooni’s premium products and carries a higher price to match its size and specification. Check current prices below:
Which Should You Buy?
The Karu 2 is the right choice if portability matters to you, if you’re cooking for 1-3 people, or if you want your first quality multi-fuel pizza oven without spending at the top of the range. It produces genuinely excellent pizza and the compact size makes it easier to store when not in use.
The Karu 16 is the right choice if you’re serious about pizza cooking, regularly cook for larger groups, want the experience of cooking with a real fire on a substantial oven, and are happy for it to be a more permanent fixture in your garden. The larger stone and better heat retention make it a more capable cooking platform.
If you’re unsure, also consider the Ooni Koda 16 – a gas-only alternative at a similar price to the Karu 16 that many people find easier to use day-to-day.
