A practical comparison
First-generation Koda 12 or 16? Start with the pizza size
The first-generation Koda 12 and Koda 16 share a propane-first, one-control outdoor routine, but their cooking floors make them different tools. The Koda 12 is built around a single 12-inch pizza and low carrying weight; the Koda 16 is the roomier choice for one pizza up to 16 inches and more turning space. The newer Koda 2 is a third, distinct choice: a 14-inch gas oven from the next generation, not a renamed Koda 12.
Start with the pizza you actually make
If 10- to 12-inch pies are your norm, the Koda 12 wastes less table and storage space. Ooni's North American manual rates its burner at 13,300 BTU per hour; the product listing publishes a 10 mm stone and claims a 950°F maximum in 15 minutes. The page gives two nearby weights—20.2 pounds in its specification table and 20.4 pounds in its portability copy—so treat the 20.4 figure as the conservative number for lifting decisions. It remains the only one of these three with a manufacturer-claimed weight around 20 pounds.
Choose the Koda 16 when 14- or 16-inch pies, a larger peel and room to turn are genuine needs. Its L-shaped burner is a first-generation feature Ooni says spreads heat across the floor. Its stone is listed at 15 mm, and the manufacturer claims a 950°F maximum in 20 minutes. The specification table says 40.1 pounds, while the product description says 42; assume the higher figure when planning the lift or support. The extra floor does not mean it cooks two full pizzas simultaneously or that it turns them automatically. Both Koda ovens leave flame and pizza management to the person at the oven.
Consider the newer Koda 2 as a different compromise
The current Koda 2 gives you a 14-inch standard-stone limit and a current-generation tapered burner design. It is listed at 35.27 pounds, heavier than the Koda 12 but lighter than the Koda 16. It remains a single-zone propane setup with manual flame adjustment; phone monitoring requires a separate compatible hub and powered rotation reduces the supported pizza size. Compare the exact [Koda 2 review](/reviews/ooni-koda-2/), rather than carrying an old Koda feature across the generation boundary.
For the larger single-pizza routine, read the [Koda 16 review](/reviews/ooni-koda-16/). For portability and 12-inch pies, see the [Koda 12 review](/reviews/ooni-koda-12/). The Koda 16's larger chamber is not automatically the best choice if a 12-inch pie already meets the meal: you pay in weight, counter space, fuel handling and storage volume. The Koda 12 is not automatically best either if the smaller opening makes launching, turning or serving your usual pizza awkward.
Do not let a shopping label settle fuel or installation
Ooni's US native catalogue identifies the first-generation Koda 12 as SKU UU-P06A00 and Koda 16 as SKU UU-P0AB00; both are listed as propane-tank models. The Koda 16 product page has a copied hose note mentioning natural gas, and Ooni's support library separately lists natural-gas line and conversion-kit documents. Those do not convert this one propane catalogue row into a factory natural-gas configuration. Buy or install a conversion only after finding the exact manufacturer instructions and verifying the exact kit, version and local installation requirements. The Koda 12 manual discusses conversion to a fixed propane system, not an automatic natural-gas permission.
Both North American manuals require outdoor operation and warn about combustibles, overhead structures, gas-cylinder position, wind, hose routing, leak checks and moving a hot oven. They contain more than one kind of clearance warning, including side/back measurements and a broader 10-foot instruction. Plan a genuinely open location and follow the whole manual and local rules; do not collapse those directions into a convenient single number. Neither compact appearance nor a “portable” label permits indoor, garage or balcony use.
Use the finder to name the limiting need
Select propane and outdoors first. Enter the largest pizza you actually intend to launch, rather than the oven's advertised maximum as a target. For a 12-inch limit, the Koda 12 may fit and the larger models can still work; for a 13- or 14-inch pizza, it is excluded while the Koda 16 and Koda 2 remain candidates. At 15 or 16 inches, only the Koda 16 among these three meets the standard-stone diameter. If you require phone monitoring, simultaneous pizzas, indoor cooking or powered turning, add those constraints—they remove these base Koda setups instead of quietly upgrading them.
Finally, include earlier models if you want to consider the first-generation ovens; by default, the finder starts with current-reference products. Neither first-generation product is guaranteed to be in stock just because its product page remains online. Confirm the exact model, generation, fuel and box contents with a seller before purchase, and keep the manufacturer's safety manual with the oven. The useful distinction is not “old versus new” in the abstract. It is whether a light 12-inch oven, a larger 16-inch floor, or newer 14-inch hardware best matches your actual meal and available station.
