Our verdict
Is the Ooni Karu 2 right for you?
The Karu 2 keeps the 12-inch format but adds a glass door and built-in temperature display. It is the stronger fit than the Karu 12 when visibility and heat monitoring matter more than saving 3.5kg; gas remains an optional extra rather than part of the box.

Space and handling
How large and heavy is the Ooni Karu 2?
The Ooni Karu 2 weighs 15.5kg. At 760 × 730 × 420mm, it is best given a permanent or semi-permanent position rather than squeezed onto a small table.
Its manageable weight makes occasional repositioning realistic, which is useful if the oven cannot live outside permanently.
Fuel and heat
How hot does the Ooni Karu 2 get?
The Ooni Karu 2 runs on wood or charcoal; optional gas burner sold separately and is for outdoors only. Its maximum temperature is 500°C, with a controllable range of 110–500°C.
Wood and charcoal are included fuel choices. The optional gas burner shortens setup, but it costs extra and changes the cooking routine.
Capacity
What size pizza can the Ooni Karu 2 cook?
The Ooni Karu 2 accommodates pizzas up to 12 inches. The oven measures 760 × 730 × 420mm, so it needs a generously sized, stable work surface.
A 12-inch limit is perfectly workable for individual pizzas, although it leaves less room for error when launching and turning. Bigger households may find the one-pizza-at-a-time rhythm restrictive.
The Ooni Koda 2 review adds two inches of pizza capacity and replaces fuel tending with gas control.
Controls
How do the Ooni Karu 2 controls and monitoring work?
Built-in thermometer.
The opening uses a borosilicate-glass door with clearview technology. The thermometer and door help you read the oven while tending solid fuel; they do not automate fire management.
Ownership
What does the Ooni Karu 2 require to set up and own?
Assembly details are not yet available.
Cast-aluminium nose and rear; powder-coated weather-resistant shell. The registered warranty is 5 years. Register it as part of setup so the longer term is not forgotten.
Trade-offs
What are the Ooni Karu 2’s main limitations?
The 12-inch capacity may feel restrictive if you regularly cook for a group. Solid fuel adds flexibility and involvement, but it also brings more setup, ash and temperature management; gas requires a separate burner.
Space, lifting weight and preferred fuel should settle the decision before smaller features do.
