Ooni Karu 2 dimensions are listed on Ooni’s official product page, not in the safety manual. As of November 6, 2026, that page is the place to confirm the current outer size before you measure your space. The Karu 2 is a pizza oven that burns wood and charcoal.
Size is only part of the fit. The fuel limits and placement rules in Ooni’s manual decide how much clear space you really need around the oven.
This oven gives off carbon monoxide while it burns fuel, so use it only outdoors and follow the manufacturer’s manual.
Ooni Karu 2 dimensions and overall size
The exact Ooni Karu 2 dimensions are printed on Ooni’s product page, not in the manual, so check the page for the current outer size of this compact wood and charcoal oven.
The manual covers assembly, lighting and safety. It lists the parts, including the main body, fuel tray, fuel grate, baking stone, oven door, chimney and chimney cap. It does not print an overall size, so the product page is the source to check first.
Two of the Ooni Karu 2 dimensions matter most for pizza. The first is the outer footprint, which decides whether the oven fits your table, balcony or patio. The second is the baking stone, which sets how large a pizza you can slide in. Compare the stone with your peel before you buy, and look at the Karu 12 size check or the Karu 16 size and weight guide if you want a smaller or larger oven in the same family.
What to measure before you buy
Measure the footprint, the height with the chimney fitted, and the surface the oven will sit on before you order, because Ooni Karu 2 dimensions can differ between listings. Treat every number as unconfirmed until you see it on Ooni’s page.
Use the same units for every number. Product pages often show centimeters and inches, and some listings show the boxed size, which is larger than the oven itself.
- Footprint: the width and depth of the spot, with room at the front for the door and fuel hatch.
- Height: the total height with the chimney on, plus space above it for the flue.
- Clearance: room between the oven and any wall, fence, hedge or overhang.
- Surface: a level, stable, non-flammable table or stand.
- Carry path: the route from the car or door to the spot, including steps and gates.
- Reach: room to stand while you load fuel and turn pizzas.
Mark the footprint with tape on the ground before you buy. Standing inside the marked spot shows whether you can open the door and reach the fuel hatch without leaning over a hot surface.
Leave room for the way you cook, too. You will turn pizzas, reach for a peel and set down a plate, so a spot that fits the oven exactly can feel cramped once you start. A little extra space on each side makes the setup easier to use day to day.
How heavy is the Karu 2, and how do you handle it?
The weight is on Ooni’s product page rather than in the manual, so confirm it there before you plan a move.
The manual is direct about handling. It warns that the oven becomes very hot and must not be moved during operation. Wait until it is fully cold before lifting it or putting it away.
Plan the lifting route before you start. A second person helps on steps, gates and uneven ground, and it keeps your hands clear of hot surfaces.
Check the surface you plan to lift onto as well. A table or stand that wobbles is a poor choice before the oven is even lit, so test that it feels solid first.
Store the oven only after all embers are out. The manual says to make sure embers are extinguished before storing, so do not put it in a shed while it still smolders. If you wonder whether the oven can stay out between cooks, read can you leave a pizza oven outside first.
Fuel and firing limits that shape your setup
The manual caps each load at 0.4 kg and limits wood pieces to 15 cm long and 4 cm across.
These limits decide how much fuel you keep beside the oven. The fuel tray takes wood and charcoal, so store both dry and close to the spot, and read about charcoal pizza oven temperatures if you plan to burn charcoal.
- Wood: dry, untreated hardwood up to 15 cm (5.9 in) long and 4 cm (1.5 in) in diameter.
- Load: no more than 0.4 kg added at one time.
- Tray: no more than 0.5 kg in the tray at any moment.
- Preheat: at least 30 minutes with the fuel red hot before the first cook.
- Ash: do not cook until the fuel has a coating of ash.
- Lighting: firelighters that meet EN 1860-3 only, and never spirit or petrol.
The two load limits work together. The 0.4 kg cap applies to each addition, and the 0.5 kg cap applies to whatever is in the tray at any moment. Refill in small batches rather than stacking the tray, so you stay inside both limits while you cook.
Read the full rules in Ooni’s Karu 2 safety manual before the first fire. The manual is the source for every fuel limit in this section.
Two parts need attention during use. The chimney cap must stay off while the oven is lit, and the draft defender plate must be fully secured before you start.
Set out the fuel, tools and firelighters before you light the oven, so you do not have to step away from it while it burns.
Where the oven can and cannot sit
The Karu 2 is for outdoor use only, on a level, stable, non-flammable surface, and never in an enclosed space.
The manual warns against any confined or habitable space, including houses, tents, caravans, motor homes and boats. Burning fuel gives off carbon monoxide, and the manual notes that poisoning from it can be fatal.
- Outdoors only, well away from flammable materials.
- A flat, stable, non-flammable surface.
- Children and pets kept well away at all times.
- Never left unattended while lit.
- The door stays in place while the oven is lit.
The manual asks for an appropriate outdoor environment well away from flammable materials. A spot tucked against a fence or under a low roof may look sheltered, but it sits closer to the materials the manual warns about.
If a spot has walls or a roof close overhead, treat it as enclosed and choose another place. A covered patio can count as an enclosed space for this purpose, so check before you set up.
Common mistakes when checking size
The most common error is measuring only the oven body and forgetting the chimney, the clearance and the surface it sits on.
- Using an old listing instead of checking the current figure on Ooni’s product page.
- Mixing up boxed and unboxed sizes when you read Ooni Karu 2 dimensions on a retailer page.
- Ignoring the chimney height when checking overhead room.
- Forgetting fuel storage and tools that also need space beside the oven.
- Assuming the Karu 2 Pro has the same size, since it is a separate model.
Before you rely on any Ooni Karu 2 dimensions from a third party, compare them with the official product page. Where a listing disagrees with that page, trust the page the manufacturer keeps current.
Write each measurement down with its unit and its source. A short list stops you from comparing a boxed size with an unboxed one by mistake.
Frequently Asked Questions
Where can I find the current Ooni Karu 2 dimensions?
Check Ooni’s official product page for the Karu 2, which lists the current outer figures. Ooni’s manual covers assembly, lighting and safety, and it does not print an overall size, so measure your spot against the product page numbers. Write down each unit, and note whether a listing shows the boxed or unboxed size.
Can I use the Karu 2 indoors?
No. The manual says not to use the oven indoors or in any confined or habitable space, such as houses, tents, caravans, motor homes or boats, because burning fuel gives off carbon monoxide. Use it only outdoors, well away from flammable materials, and keep children and pets away.
How much fuel can I load at one time?
Add no more than 0.4 kg of fuel at one time, and keep no more than 0.5 kg in the tray at any moment. Wood pieces should be dry, untreated hardwood up to 15 cm long and 4 cm across. Refill in small batches so you stay inside both limits.
How long should I preheat the oven?
Heat the oven and keep the fuel red hot for at least 30 minutes before the first cook. Do not start cooking until the fuel has a coating of ash, as the manual directs. Keep the chimney cap off and the draft defender plate secured while the oven is lit.
Which fuels does the Karu 2 burn?
The fuel tray is designed for wood and charcoal. Use only charcoal that is suitable for cooking, and light it with firelighters that meet EN 1860-3, never spirit or petrol. Wait until the fuel has a coating of ash before you cook food.
Does the manual list the weight?
No. Ooni’s manual does not list the weight, so check the figure on Ooni’s product page and confirm whether it is the unboxed weight. The oven gets very hot in use and must not be moved while it runs, so plan the lifting route and wait until it is fully cold.
Before you buy, confirm the current Ooni Karu 2 dimensions and weight on Ooni’s product page and measure the spot with the chimney in place, then compare other sizes in the oven model guides. If the spot has walls or a roof close overhead, choose another place. Keep fuel dry and within easy reach, and let the oven cool fully before you move or store it.
