Main trade-off
Ooni Koda 2
It weighs 5.27 lb more on the published figures.
Head-to-head
Choose Koda 2 when a 14-inch pizza is a real requirement or its selected peel-and-cover bundle fills gaps in your equipment. Choose Pi Prime for 12-inch propane pizza and a 30-pound body. Both are outdoor gas ovens, and Ooni's recovery claims against Koda 12 do not establish a recovery advantage over Pi Prime.
Before you choose
A 14-inch round pizza has about 36.1% more nominal surface area than a 12-inch round pizza, using the square of the diameter ratio. Koda 2 provides that larger rated option. Pi Prime still suits a household making individual 12-inch pizzas, and a larger pizza does not guarantee a proportionally larger number of servings.
What this is based on
Calculation is 14 squared divided by 12 squared minus one. Dough thickness, toppings and appetite are held outside the calculation, so it is not a serving or throughput claim.
Main trade-off
It weighs 5.27 lb more on the published figures.
Main trade-off
It is limited to a 12-inch pizza rating.


Compare the Koda 2 Essentials bundle and Pi Prime for 14-inch versus 12-inch pizza, included tools and realistic carrying trade-offs.
The practical choice turns on rated pizza size and fuel, then on the constraints in your own setup.
Winner by situation
Koda 2 supports that diameter, while Pi Prime is rated for 12 inches.
Pi Prime has the lower published body weight, with carrying suitability still individual.
The selected Koda Essentials listing includes both.
Ooni's Koda 12 comparison does not test Pi Prime.
What matters in practice
A 14-inch round pizza has about 36.1% more nominal surface area than a 12-inch round pizza, using the square of the diameter ratio. Koda 2 provides that larger rated option. Pi Prime still suits a household making individual 12-inch pizzas, and a larger pizza does not guarantee a proportionally larger number of servings.
Calculation is 14 squared divided by 12 squared minus one. Dough thickness, toppings and appetite are held outside the calculation, so it is not a serving or throughput claim.
Pi Prime's stated 30-pound weight is 5.27 lb below Koda 2's 35.27 lb. That can matter if the oven is frequently moved after cooling, but Koda's selected bundle includes a carry cover that may suit storage. Neither weight includes a propane cylinder or proves that a particular person can carry it comfortably.
The subtraction compares published oven weights. Check handles, packed shape, route and table height separately, and follow the fuel-disconnection and cool-down instructions.
The chosen Koda 2 Essentials bundle includes a 12-inch peel, even though the oven is rated for 14-inch pizza. If your reason for buying is routinely making a full 14-inch pizza, confirm an appropriate compatible launch tool rather than assuming the bundle's peel matches the maximum diameter.
This conclusion follows from exact bundle contents and oven capacity. Pi Prime's package also needs a separate peel check, so tool planning applies to both.

Ooni, 14-inch propane oven essentials bundle
A compact gas oven with Ooni's newer tapered flame and a thicker stone for faster recovery between 14-inch pizzas.

Solo Stove, 12-inch propane oven, stainless steel
A simple propane oven with a wide mouth, two-piece stone and clearly marked heat dial that helps new cooks find the useful zone quickly.
Meaningful differences
| What changes | Ooni Koda 2 | Solo Stove Pi Prime | Why it matters |
|---|---|---|---|
| Rated pizza size | Up to 14 inches | Up to 12 inches | Koda accepts a larger diameter, subject to the matching tool and recipe. |
| Fuel | Propane | Propane only | Both need an appropriate outdoor gas setup. |
| Published body weight | 35.27 lb | 30 lb | Pi Prime is 5.27 lb lighter on the published figures. |
| Selected accessories | 12-inch peel and Koda 2 carry cover in Essentials bundle | Oven package without a listed peel | The included Koda peel does not itself become a 14-inch peel. |
| Stone | 15 mm cordierite | Two-piece cordierite | Stone construction differs without a measured recovery comparison. |
| Published high heat | Up to 950°F | Up to 900°F in current guidance | The maximum claims do not predict every recipe's bake time. |
What you give up
Recommendation switch
Choose Ooni Koda 2. Koda 2 supplies the larger rated diameter.
Choose Solo Stove Pi Prime. Pi Prime is the lighter published oven.
What matters in practice
Koda 2's extra diameter matters when your normal recipe is a larger shared pizza. It may matter little if everyone chooses separate toppings on a 12-inch base. The area calculation describes dough footprint, while the actual meal depends on thickness, toppings and how the pizzas are served.
The Koda listing supplies a 12-inch peel and a carry cover. Those are useful additions, but they do not prove that every 14-inch launch is covered by the included tool. Pi Prime should likewise be compared with the tools you already have or intend to add.
Ooni's published improvement is measured against its older Koda 12. It is not a head-to-head result against Pi Prime. For this pair, the credible distinctions are pizza diameter, listed weight, package and stone design, without inventing an advantage in back-to-back cooking.
