Wood-fired and multi-fuel
Ooni Karu 2: a wood oven light enough to actually move
33.6 pounds, a full glass door and a 13.3 inch stone. It is the only oven on this site that burns wood and is still genuinely portable — and the door is the feature that makes wood firing bearable.
The short answer
Buy the Karu 2 if you want wood on a small patio. At 33.6 lb it is the lightest wood-capable oven here, the borosilicate glass door lets you manage the fire without opening the chamber, and the 13.3 in stone takes a medium Detroit pan as well as a 12 in round. Budget separately for the gas burner, and accept that 12 in is the ceiling.
Wood-fired cooking has a specific frustration that nobody warns you about. You want to know what the fire is doing; the only way to find out is to open the oven; opening the oven vents the chamber and changes what the fire is doing. You have measured the thing by destroying it, roughly fifteen times an evening.
The Karu 2's glass door removes that loop, and at this weight and price nothing else does.
The door is the product
Ooni publishes a borosilicate glass door with ClearView and a built-in thermometer. Those two together change how the oven is used: you read the fire and the temperature by looking, and you open the chamber only to launch and retrieve.
It is the single clearest reason to choose the Karu 2 over the older Karu 12, which has no door and is the reason that model sits on our skip list. Wood has no dial — the door is the closest substitute.
33.6 pounds, and what that unlocks
Published external dimensions are 28.3 in L x 16.5 in W x 30.3 in H, at 33.6 lb unboxed and 45.8 lb boxed.
For context, the Karu 2 Pro is 62.6 lb and the Gozney Roccbox is 44 lb. Nothing else that burns wood on this site is under 40 lb. That makes the Karu 2 the only wood oven that realistically comes out of a shed for an evening and goes back afterwards — which matters, because an oven that lives outdoors all winter is an oven with water in it.
One caveat on the portability: it stands 30.3 in tall with its chimney and legs. The footprint is modest but the shape is awkward, and it is not a designed-to-travel oven the way the Roccbox is — that comparison is here.
The 13.3 inch stone does something unexpected
Ooni publishes a 13.3 in cordierite stone at 0.6 in (15 mm), taking a 12 in pizza — and also a medium Detroit-style pan.
Very few ovens at this size accept a pan, and it meaningfully widens what the oven is for. A Detroit or Sicilian bake wants a long, moderate cook rather than a 90-second blast, which is exactly the sort of thing a wood fire settling down after its peak is good at. It is the most useful under-advertised specification on this oven.
The honest limitations
12 in in a 13.3 in chamber. That is about 0.65 in of clearance per side — tight. Turning a 12 in pizza in here needs a genuinely small turning peel and a steady hand, and it is exactly the geometry that produces the one-burnt-edge problem. Cook 10 to 11 in pizzas and the oven becomes far more forgiving.
The gas burner is a separate purchase. The Karu 2 ships wood-and-charcoal ready. "Multi-fuel" is accurate but the advertised price is the wood-only price, and if you want the weeknight convenience of a dial you are adding a burner to the basket. Compare configurations, not stickers.
0.6 in stone. Thinner than the 0.8 in floors in the Gozney Arc family, and wood firing is where floor heat does the most work. Expect a genuine recovery pause between pizzas.
Wood in a small firebox needs feeding often. The fuel tray is a few inches across, so this is kindling-sized wood on a short cycle — see choosing wood. Lump charcoal is the lower-effort option and it works well here.

Ooni Karu 2 Multi-Fuel Outdoor Pizza Oven
Ooni · Multi-fuel
The Karu 2 Pro's idea at 33.6 lb: wood and charcoal standard, optional gas burner, glass door, built-in thermometer, 13.3 in stone. The most portable real wood oven here.

What it does well
- 33.6 lb makes it the only wood-capable oven here that is genuinely portable
- A glass door at this size and weight is the standout feature — you watch the fire instead of opening the oven and losing it
- The 13.3 in stone takes a Detroit pan, which very few 12 in ovens do
What you give up
- 12 in pizzas in a 13.3 in chamber: turning room is tight and the one-side burn problem is real here
- Gas burner sold separately, again
- Wood in a small chamber means feeding the fire often — small ovens have small fuel trays
Buy it if
A small patio where wood flavor matters more than pizza diameter.
Skip it if
Anyone cooking for six, or anyone who wanted the simplicity of a dial.
Where these numbers came from
Two comparisons bracket this oven. Below it, the first-generation Karu 12 shares the same 950 F and the same 0.6 in floor and gives up the glass door. Above it, the Karu 2 Pro adds four inches and a food probe for 29 lb, without thickening the stone.
How these picks were made
We did not cook on these ovens. Every figure on this page is the maker’s or the listing’s published specification, cited on each write-up so you can check it in one click. The ranking comes from matching those published capabilities to a stated use case — space, pizza size, fuel, and how many pizzas you cook in a row. Where a maker does not publish a number, we say so instead of estimating one.
The full version of that argument, including what we deliberately do not claim, is on our methodology page.
