The best wood for Ooni Karu 12 is compact, dry hardwood that fits the fuel tray, and oak logs are a sensible starting point. VERSAWOOD’s 5-inch barkless oak logs have the shortest stated length in this roundup, while 6-inch options suit buyers whose tray has room for them.
Karu 12 owners should think about length and thickness before wood type alone. A piece that sits awkwardly can crowd the tray, so measure the usable space and leave room for air to move around the fire.

How we chose wood for Ooni Karu 12
We compared the stated wood type, piece length, fuel form and intended cooking use for each option. Fuel compatibility differs by model; see whether the Ooni Karu 2 Pro works with natural gas.
The Karu 12 has a small fuel tray, so we gave more weight to short solid wood than to pellets made for other oven or grill systems.
Our score weighs specs, features and buyer feedback against what you're shopping for. Product descriptions can identify a length or wood type, but your tray's usable space is the final fit check.

Best wood for Ooni Karu 12 by fit and fuel type
The top options are solid oak logs with stated lengths that make tray fit easier to judge. Pellet products appear lower because the Karu 12 uses wood and charcoal, and their compatibility should be confirmed with Ooni before use.
VERSAWOOD Kiln-Dried Oak Wood for Pizza Ovens: Best for the shortest tray fit
- 5-inch oak logs
- Kiln-dried
- Barkless
- About 12 lb
Its 5-inch barkless oak logs are the shortest solid-wood pick here, which can make tray fit easier to check for the Karu 12. VERSAWOOD describes it as kiln-dried.
Pros
- Shortest stated log length here
- Oak hardwood
- Kiln-dried
Cons
- Measure the usable tray space before choosing a log length
- Solid wood needs tending as it burns
VERSAWOOD’s 5-inch barkless oak logs are the shortest solid-wood pieces in this group. That compact length makes them the easiest starting point if you want to reduce trimming or awkward placement in a small fuel tray.
The wood is kiln-dried oak, and the box is about 12 lb. Those details give you a clear basis for comparing fuel form and storage, while the shorter pieces may also be easier to handle beside a compact oven.
Length alone does not guarantee a fit. Measure the tray's usable area and compare it with both the logs’ length and thickness before loading, especially if you plan to stack more than one piece.
Choose this option if you want oak logs with a short stated length. It is the most direct match in this list for shoppers prioritizing compact solid wood for the Karu 12.
Gimgsoen Pizza Oven & Cooking Wood: Best for 6-inch oak logs
- 6-inch oak sticks
- Kiln-dried
- Bark-free
- 15 lb box
This box pairs kiln-dried, bark-free oak with a stated 6-inch stick length. Check whether that length fits your tray before ordering.
Pros
- Oak sticks with stated length
- Kiln-dried and bark-free
- 15 lb box
Cons
- Longer than the 5-inch logs in this roundup
- Tray fit depends on usable space
Gimgsoen offers kiln-dried, bark-free oak sticks cut to 6 inches. That gives you a consistent stated length to compare against the Karu 12 tray, but you should verify the fit before ordering.
The 15 lb box provides more wood by weight than the 12 lb options here. Its oak form is a straightforward choice for cooks who want solid fuel and can comfortably position 6-inch pieces in the tray.
The product is also described for other outdoor cooking uses, including grills and smokers. For a compact oven, the useful details are the oak material and stick length, not the broader list of cooking applications.
Choose it if 6-inch logs fit your tray and you want a larger box. If the tray is tight, compare the 5-inch VERSAWOOD logs first.
Kona Wood Pellet Variety Pack for Ninja: Best for comparing pellet flavors
- Eight 1 lb varieties
- Includes oak and blends
- Pellets for grills and smokers
- Not designed for hopper-fed grills
This pack offers eight pellet varieties, including oak and several blends. It is described for grills and smokers, not as a solid-log fuel for the Karu 12.
Pros
- Multiple wood flavors in one pack
- Includes oak
- Useful for grill or smoker cooking
Cons
- Not a solid-wood option for the Karu 12 tray
- Not designed for hopper-fed grills
Kona’s variety pack is a pellet product with eight 1 lb flavors, including oak, hickory, cherry, apple and blends. It offers variety for grilling and smoking, but it is not the same fuel form as the solid wood sticks used in a Karu 12.
The pack is described for grills and smokers, including use in a smoker tube or sprinkled onto charcoal. It is not designed for hopper-fed pellet grills, and its intended use does not guarantee compatibility with the Karu 12.
Choose it if you want a range of smoke flavors for a compatible grill or smoker. For Karu 12 cooking, confirm any pellet use with Ooni before trying it.
VERSAWOOD Oak Wood Pellets: Best for oak pellet ovens
- 100% oak hardwood
- Kiln-dried
- 10 lb bag
- Pellet fuel
These oak pellets are made for pellet pizza ovens and smokers. The Karu 12 uses a wood and charcoal fuel tray, so confirm fuel compatibility before buying.
Pros
- Oak hardwood pellets
- Kiln-dried
- Additive-free according to VERSAWOOD
Cons
- Pellet fuel, not mini logs
- Compatibility with the Karu 12 is not established here
VERSAWOOD’s oak pellets are kiln-dried hardwood in a 10 lb bag. The maker describes them for pellet pizza ovens and smokers, which makes them a closer fit for pellet-fueled equipment than for the Karu 12’s wood and charcoal tray.
The product is described as additive-free and made from oak. Those details may matter if you are comparing pellet fuel for another oven, but pellets do not provide the same piece size or loading method as mini logs.
Choose these pellets for a compatible pellet oven or smoker. If you are shopping specifically for a Karu 12, start with solid logs and confirm fuel guidance in the oven manual.
FLAMEWOOD LLC ENJOY YOUR FIRE 14 Lbs Pizza: Best for white oak splits
- White oak mini splits
- About 6 in long
- Bark-free
- Kiln-dried
These kiln-dried, bark-free white oak splits are about 6 inches long. Their size may suit some compact ovens, but measure the Karu 12 tray before choosing them.
Pros
- White oak mini splits
- Bark-free and kiln-dried
- Stated length and thickness range
Cons
- Some splits may be thicker than others
- 6-inch length needs a tray fit check
FLAMEWOOD’s white oak mini splits are about 6 inches long and range from 0.5 to 1.5 inches thick. They are kiln-dried and bark-free, giving you both length and thickness to compare with the tray.
The box contains 14 lb of wood. White oak is the specified wood, so this option suits shoppers who want a hardwood split and have enough room to load pieces of this size without crowding the fire.
Some pieces can be thicker than others, so check more than one split against the tray dimensions if the fit is close. Choose this option when your measurements support 6-inch pieces and you prefer white oak.
Woodover Pizza Oven Wood: Best for 6-inch white oak logs
- Kiln-dried white oak
- 6-inch logs
- 12 lb box
- About 800 cu in
Woodover offers kiln-dried white oak in 6-inch logs. The stated length is useful for comparison, though the Karu 12 tray should decide whether each log fits.
Pros
- White oak
- Kiln-dried
- Logs have a stated length
Cons
- 6-inch logs may be too long for some tray positions
- Box volume does not show how many sessions it will last
Woodover sells kiln-dried white oak logs cut to 6 inches, with a 12 lb box. The stated length gives you a clear comparison point, though the product does not specify a thickness range here.
The product is described for compact ovens and tabletop fire pits. That broad use can help identify the intended scale, but it does not confirm that every log fits the Karu 12 tray.
Choose it if your tray has room for 6-inch pieces and you want white oak logs. Check thickness and fit before loading, particularly if airflow space is limited.
Kona Wood Pellets Pizza Blend: Best for pizza oven pellets
- Hardwood pizza blend
- Pellet fuel
- 2 lb resealable bag
- Intended for Ooni and Big Horn pellet ovens
Kona’s pizza blend is a hardwood pellet made for pellet pizza ovens. The Karu 12 uses wood and charcoal, so verify compatibility instead of treating pellets as interchangeable with logs.
Pros
- Pizza-focused hardwood blend
- Resealable bag
- Intended for pellet ovens
Cons
- Pellets are not mini logs
- Karu 12 compatibility is not established here
Kona’s pizza blend is a 2 lb hardwood pellet product intended for Ooni and Big Horn pellet pizza ovens. The Ooni name alone does not mean it suits every Ooni model, since the Karu 12 uses a different fuel setup from a pellet oven.
The resealable bag is convenient for storing a smaller amount of pellets. Use this option only with equipment whose instructions support this pellet fuel.
Choose it if you have a compatible pellet pizza oven and want a pizza-focused hardwood blend. For a Karu 12, compare solid wood logs instead.
W&E Choice Pizza Oven Wood 6 Inch: Best for a 12 lb oak box
- 6-inch oak mini logs
- Kiln-dried
- 12 lb box
- For pizza ovens and grills
The 6-inch kiln-dried oak logs give you a clear size to compare with the Karu 12 tray. Measure before buying, especially if you want to load several pieces at once.
Pros
- Oak mini logs
- Kiln-dried
- Stated 6-inch length
Cons
- Length may limit how logs sit in the tray
- No smaller size is specified
W&E Choice offers kiln-dried oak mini logs cut to 6 inches in a 12 lb box. The stated size makes comparison simple, but it is longer than the 5-inch option and may not sit as easily in every Karu 12 tray position.
The oak logs are also described for grills and smokers. For the Karu 12, focus on whether each piece fits and leaves room around the fire rather than relying on general oven compatibility language.
Choose it if you want a 12 lb box of 6-inch oak and your measurements confirm the fit. If you need a shorter piece, consider the 5-inch logs at the top of this roundup.
Kona Pizza Oven Wood Pellets: Best for Ninja Woodfire cooking
- Apple and oak blend
- 2 lb bag
- Pellet fuel
- For Ninja Woodfire grills and ovens
This apple and oak pellet blend is intended for Ninja Woodfire grills and ovens. It is a flavor option for compatible pellet cooking setups, not a substitute for Karu 12 mini logs.
Pros
- Apple and oak blend
- Small 2 lb bag
- Intended for Ninja Woodfire cooking
Cons
- Pellet fuel rather than solid wood
- Karu 12 compatibility is not established here
Kona’s apple and oak blend is a 2 lb pellet product intended for Ninja Woodfire grills and ovens. Its blend and small bag may suit compatible equipment, but they do not make it a solid-wood option for the Karu 12 tray.
The product is described for pizza, breads and vegetables cooked in a compatible setup. Check the instructions for your oven before using a pellet fuel that is not specified for it.
Choose this only if you have a compatible Ninja Woodfire system or another setup that supports the pellets. For the Karu 12, choose a short solid log instead.
What size wood should you buy for the Karu 12?
Start with the tray's usable length and width, then compare those measurements with the pieces you plan to buy. In this roundup, solid wood lengths are 5 or 6 inches, while thickness details vary or are not stated.
The 5-inch oak logs are the shortest option here. Six-inch pieces may fit, but the answer depends on how the tray is shaped and how much room remains for air circulation.
Which wood type works well in a small pizza oven?
Oak is a common practical choice among the solid cooking woods in this roundup. Several options are oak, including white oak, and the product details describe kiln-drying for those logs.
For more on choosing species and sizing fuel, read best wood for Ooni pizza oven and the broader guide to How to Choose Wood for a Pizza Oven?. If you are weighing fuel styles, Which Is Better Gas or Wood Pizza Oven? covers the tradeoffs.
Are pellets a good substitute for Karu 12 logs?
Pellets are not automatically interchangeable with mini logs. Several pellet products in this roundup are intended for pellet ovens, Ninja Woodfire equipment, grills or smokers, so check Ooni's instructions before using them in a Karu 12.
Chips and pellets are also different from the short logs usually used in a compact wood fire. See How to Use Wood Pellets in a Pizza Oven? for pellet guidance, and Can You Use Wood Chips in an Ooni Pizza Oven? for chip-specific questions.
Should you choose wood or charcoal for the Karu 12?
Choose wood when you want a live flame and the aroma associated with wood-fired cooking. Charcoal is another fuel option for the Karu 12, so your preference depends on the cooking style and the oven instructions.
If you want a charcoal option, compare our best charcoal for Ooni pizza oven. Use the fuel load and lighting method recommended for your exact Karu model.
Which wood is the best fit for your Ooni Karu 12?
Choose the 5-inch VERSAWOOD oak logs if you want the shortest stated solid wood in this roundup. Pick a 6-inch oak or white oak option when your tray measurements leave enough room, and use pellet products only with equipment whose instructions support them.

Frequently asked questions
What wood size fits an Ooni Karu 12?
Choose short pieces that sit securely in the Karu 12 fuel tray without blocking airflow. The products here range from 5 to 6 inches long, so measure the tray's usable space and compare each piece before you buy.
Shorter pieces can be easier to position, but the tray fit also depends on their width.
Is oak a good wood for the Ooni Karu 12?
Oak is a practical hardwood choice for a small wood-fired oven because several compact cooking-wood options are sold as oak logs. Look for dry, clean-burning pieces in a length that fits the tray.
Avoid treated, painted or glued wood, which is not meant for cooking.
Can you use wood pellets in the Ooni Karu 12?
The Karu 12 is designed around wood and charcoal fuel, while pellets are a different fuel form. Check Ooni's guidance for your exact oven before trying a pellet product, since compatibility should not be assumed from a general pizza oven label.
Use the fuel type the oven maker specifies.
Can you mix wood and charcoal in an Ooni Karu 12?
The Karu 12 is designed for wood and charcoal, and the right choice depends on the heat and flavor you want. Wood is often chosen for its live flame and aroma, while charcoal can provide a steady base.
Follow the oven manual for safe loading and fuel use.
Read our best charcoal for Ooni pizza ovens for charcoal options.
Are wood chips suitable for an Ooni Karu 12?
Wood chips are much smaller than the mini logs typically used in a compact pizza oven fire. Check Ooni's instructions before using chips, and do not assume a smoker accessory fuel works in the Karu 12.
Our guide to Ooni pizza oven wood chips explains the difference between chips and cooking logs.
