How to choose a pizza oven

Decision 1: where will it live?

This comes first because it can eliminate whole categories before you look at a single oven.

A balcony or apartment frequently rules out gas altogether — many leases and local fire codes restrict open-flame appliances and cylinder storage, and gas ovens require genuine outdoor ventilation with open sky above. Check before shopping, not after; the balcony rules guide covers the three things to look at.

A permanent outdoor site removes weight as a constraint entirely, which changes the answer completely — buy the thickest stone and best insulation in budget. A space the oven leaves between uses makes weight and format the dominant specifications. That is the built-in versus portable decision, and it belongs here rather than later.

Decision 2: which fuel?

Gas unless you have a specific, honest reason otherwise. It has a dial, it holds temperature without supervision, and it is the fuel that survives a Tuesday. The strongest predictor of good home pizza is how many times you cook it, and gas is the fuel that produces repetitions.

Wood or multi-fuel if you genuinely want the live-flame char and will accept feeding a fire, cleaning ash and a heavier oven. Be honest with yourself here — owners consistently overestimate this. And note the smoke-flavor claim is largely folklore at a 90-second bake, for reasons the fuel guide sets out.

Electric if the oven has to live indoors. 850 F on a kitchen counter is roughly 300 F above a domestic oven, and it gets used in February.

Decision 3: what size, really?

Take the largest pizza you will actually cook and add two inches. That is your minimum chamber size, and the addition is not padding — it is turning clearance.

A 12 in pizza in a 12 in oven cannot be rotated, because there is nowhere to insert a turning peel. One edge then faces the burner for the whole bake, which is the origin of most half-burnt home pizzas. See why one side burns.

Most people make 11 to 12 in pizzas, which means a 14 in oven is the practical minimum and a 16 in oven is comfortable. Above 16 in you are buying for a crowd rather than for quality.

Decision 4: how many pizzas in a row?

This is the question that selects stone thickness, and it is the specification almost nobody reads.

The floor cooks the base, and a floor gives up stored heat as it does so. A 0.4 to 0.5 in stone fades noticeably after two pizzas. A 0.8 in stone carries three or four without a pause. Across the ovens on this site that number ranges from 0.4 to 0.8 in — a factor of two in stored energy.

Cooking for two: thickness barely matters, and a thinner stone preheats faster. Feeding a table: buy on this number above almost anything else.

Decision 5: budget, and what it actually buys

In descending order of usefulness: chamber size, stone thickness, insulation, then features.

The first three change the pizza. The fourth — digital gauges, Bluetooth hubs, food probes — changes the convenience, and an infrared thermometer replaces most of it for a fraction of the money. If your budget is tight, spend it on the chamber and buy the thermometer separately.

Budget for the accessories too: a peel sized to the oven's mouth, a thermometer, a turning peel and a cover. Some ovens include one or two of those — the Gozney Roccbox includes a peel, the Breville Pizzaiolo includes a peel and a pan, Bertello's bundles include most of it — which materially changes the real price. See what you actually need.

The specifications that are mostly noise

Peak temperature. Every gas oven here publishes 950 F except one at 900 F. It does not differentiate them.

"Cooks a pizza in 60 seconds." Also universal, and it is a function of temperature rather than of the oven's design. Solo Stove's honest 90 seconds is the only figure on this site that deviates.

BTU ratings, because almost nobody publishes one. Solo Stove publishes 15,000 BTU for the Pi Prime; Ooni, Gozney and Bertello publish nothing for their ovens. Any comparison table showing BTU for a Koda or an Arc has invented the number.
