Safety scope. Measure from outside the chamber with tools rated for the expected temperature, follow the oven and thermometer manuals, and keep hands and clothing away from the mouth, flame, elements, and hot surfaces. This page does not prescribe one universal target ratio: the correct relationship depends on the style, dough, thickness, and oven.
Ask someone what temperature they bake pizza at and they will give you one number. That number is the set-point on a dial, and it describes neither of the two temperatures the pizza actually experiences.
Learning to think in two temperatures instead of one is the single biggest upgrade available to how you read an oven. It costs nothing, it applies to every oven from a domestic electric to a wood-fired dome, and it converts most bake problems from mysteries into a choice between two adjustments.
Two temperatures, two jobs
Deck temperature is the temperature of the surface the pizza sits on. A stone, a steel, a firebrick floor, a cordierite deck. It cooks the base by conduction, which is direct contact, and conduction is by a wide margin the most efficient way heat gets into a pizza.
Deck temperature controls: whether the base sets, how much oven spring you get in the first seconds, how much colour and char appear underneath, and whether the centre finishes.
Dome temperature is the temperature of the air and the radiating surfaces above the pizza. In a domed oven that is literally the dome. In a domestic oven it is the air plus the oven walls plus, if you use it, the grill element. In a portable gas oven it is the air plus the flame.
Dome temperature controls: cheese melt and colour, rim colour and char, and how quickly the top finishes relative to the bottom.
They are set by different things, they move at different rates, and they can be adjusted somewhat independently. The set-point on your dial is a target for neither of them precisely.
Why the dial is not the answer
An oven thermostat measures air, somewhere in the cavity, and switches heating on and off to hold that air near a target. Three things follow.
- The deck lags badly. A dense stone or steel takes far longer to reach temperature than the air around it, and the oven signals "ready" based on the air. Launching at the beep is the most common single mistake in home pizza.
- The dome is not uniform. Air temperature varies by position — top to bottom, front to back, near an element or a flame versus away from one. One number cannot describe it.
- Radiant heat is invisible to the thermostat. A grill element or a flame can be putting large amounts of radiant energy onto the top of your pizza while the air temperature reads exactly on target.
This is why two people with ovens set to the same number get different pizza, and why "what temperature do you bake at" is a question with no useful answer.
Measuring deck temperature
The deck is measurable and you should measure it. An infrared thermometer is the usual tool.
Where to point. At the spot where the pizza will actually land, in the centre of that spot. Not the edge of the stone, not the oven floor beside it, not the metal frame.
Where not to point. At shiny metal of any kind. Reflective surfaces give badly wrong infrared readings, and so do surfaces at a sharp angle to you. Do not measure a steel and a stone with the same expectations either — surface material changes what an infrared reading means. The three errors that make most readings wrong are covered in infrared thermometers: why your reading is probably wrong, and that post is worth reading before you trust any number you take.
How to make it repeatable. Stand in the same place, hold the tool at the same distance, aim at the same spot, and take the reading the same way every time. Even a reading with a systematic error is useful if the error is consistent, because you can compare it against your own previous bakes. That is worth more than an accurate number you take differently every time.
Measure before and after. Take a reading just before you launch and another immediately after the pizza comes out. The difference tells you how much heat that pizza took, which is the number that governs how long you have to wait before the next one.
Measuring dome or ambient temperature
This is harder and less standardised, and it is worth saying plainly: there is no established convention for how a home baker should measure the dome temperature of a small oven. Different manufacturers, different enthusiasts, and different published specifications point at different places.
What is workable:
- In a domed or portable oven, point the infrared thermometer at the interior roof directly above where the pizza will sit. Shiny stainless interiors will give unreliable readings; a soot-darkened or refractory surface reads more usefully.
- In a domestic oven, an oven thermometer sitting on the rack near the baking surface tells you more about the air than the dial does, and will often tell you the dial is optimistic.
- Record where you measured. A dome reading without a stated measurement point is not comparable to anyone else's, including your own from last month.
Because there is no single home-baker convention, be sceptical of any published dome figure that does not say where and how it was measured. Record the measurement point with the reading so later bakes are comparable.
What the relationship controls
The interesting quantity is not either number alone but their proportion, because that decides whether the top and the bottom of the pizza finish at the same time.
| Relationship | What you get | Where you see it |
|---|---|---|
| Dome high relative to deck | Charred rim over an unset base | Small gas ovens launched too early; aggressive grill use |
| Deck high relative to dome | Dark base under pale cheese | Bottom-heavy domestic ovens; a very conductive surface in a long bake |
| Both adequate, in proportion | Base and top finish together | The target, whatever the absolute values |
| Both low | Long bake, dry pizza, poor spring | Under-preheated ovens, and the usual result of "turning it all down" |
There is no universal target ratio. A style specification can supply an initial pair of temperatures—for example, AVPN's 2024 regulations give approximate base and dome figures for Verace Pizza Napoletana—but the useful operating relationship is the one that finishes your base and top together with your dough, thickness, and oven. Find it by measuring both, baking, and noting which finished first.
The failure case in the first row of that table is common enough to have its own post: burnt rim, raw middle.
Reading the bake in progress
Numbers before the launch are half of it. The other half is what the pizza tells you while it is baking.
- Look at the base early. Lift an edge with a turning peel a short way into the bake. If it is still white when the top is already colouring, your deck is behind.
- Watch where the rim colours first. If colour appears in one place, that is positional and turning will fix it. If it appears evenly and too fast, that is the ratio.
- Watch the spring. A vigorous early rise means the deck delivered. A pizza that sits flat and then slowly colours means it did not.
- Notice the smell. Scorching flour on the deck smells sharp and bitter well before you can see it, and usually means excess dusting flour rather than an oven problem. See what to dust your peel with.
- Time it and write it down. Bake time is your best single indicator that something changed between sessions. How to log a bake sets out the fields worth keeping.
Adjusting each independently
To raise deck temperature. Preheat longer. Wait longer between pizzas. Move the surface to a position with more direct heat. Choose a more conductive surface — see steel versus stone.
To lower deck temperature. Launch sooner after a previous pizza, which uses the recovery dip deliberately. Move the surface further from the primary heat source. Use a less conductive surface for long bakes.
To raise dome temperature. Use the grill element as the manufacturer permits. Move the pizza closer to the top of the cavity. In a gas oven, raise the burner.
To lower dome temperature. In a gas oven, turn the burner down once the deck is up to temperature and before you launch. In a domestic oven, stop using the grill and move the rack down.
One at a time. Change both and you will not learn which mattered.
Working safely at these temperatures
A pizza deck at working temperature causes immediate, serious burns. This is not a caution to skim.
- The deck does not look hot. Treat any oven that has been on as hot for a long time after it is off.
- Never reach into an oven mouth with your hand. Use tools with handles long enough that your hand stays outside.
- Radiant heat from an open oven mouth burns exposed skin and singes hair. Do not lean in to take a reading; stand back and use the thermometer's range.
- Dry mitts. A damp glove conducts heat straight through.
- Keep the space around the oven clear, and keep children and pets away from the whole area.
- Portable gas ovens are outdoor appliances. Never operate them indoors, in a garage, in a tent, or in any enclosed or partially enclosed space, because of carbon monoxide risk. Follow the manufacturer's clearance and operating guidance. See portable gas pizza ovens.
- We do not publish methods for defeating a self-clean lock, a thermostat limit, a door interlock, or any other safety feature, at any review level.
Mistakes to avoid
Treating the dial as a measurement. It is a target for the air and nothing more.
Launching when the oven says ready. The deck is behind the air, often by a lot.
Measuring a shiny surface with an infrared thermometer and believing the number. Reflective surfaces read badly wrong.
Taking readings inconsistently. Different distance, different angle, different spot, different day. Now nothing is comparable.
Adjusting both temperatures at once. You will not know which change did what.
Deciding a thermometer is optional. Without measurement you are adjusting an oven by superstition, and every diagnostic post on this site becomes unusable to you.
In Plain English
Your oven has two temperatures that matter: the surface under the pizza, which cooks the base by contact, and the air and radiant heat above it, which cooks the top. The number on the dial is neither of them.
This is for anyone who sets an oven to a number, has no idea what the pizza is experiencing, and cannot therefore act on any diagnosis more specific than "it went wrong."
Use it at the start of a session, before the first launch, and again between pizzas when you are working out how long to wait.
Next step: take one deck reading before your next launch and one immediately after the pizza comes out, always from the same spot at the same distance. The gap between those two numbers is your recovery, and it is the number that tells you when to launch the next pizza.
