How We Score Pizza Ovens - And Why Our Old Scores Were Not Good Enough
This page exists because our scores were not good enough, and the fix should be public rather than quiet.
What was wrong
We audited our own ratings in August 2026. Across 16 rated reviews:
- Scores ran from 3.5 to 4.2. That is a spread of 0.7 on a five-point scale.
- Nothing scored below 3.5. Nothing scored above 4.5.
- Of 94 individual sub-scores, only 4% fell below 3.0.
- The 16 reviews used 45 differently-named sub-score dimensions between them - including "Ease of use" and "Ease of Use" counted separately, which tells you how ad-hoc it had become.
Put plainly: a discontinued pellet oven with a documented fuel-feed defect scored 3.5, and the best oven we have ever cooked on scored 4.2. If those two numbers are that close, the number is not helping you choose. And because no two reviews measured the same dimensions, the overalls were averages of different things wearing the same badge.
That pattern - everything good, nothing bad, narrow band - is what an affiliate rating looks like when it is built to justify a purchase rather than to evaluate a product. We are not going to argue that ours was different.
The six dimensions
Every oven is scored on the same six, whether or not each one flatters it.
| Dimension | What it measures |
| Heat & bake | Stone temperature we measured ourselves, time to a 60-90 second Neapolitan bake, and evenness across the stone. |
| Temperature control | Recovery between consecutive pizzas, hot spots, how finely the heat can be adjusted, and whether the measured preheat matches the marketed one. |
| Build & durability | Materials and finish, known failure modes from owner reports, and whether spares actually exist. |
| Ease of use | Setup, learning curve, fuel handling, ash and cleaning - how much work stands between you and a pizza. |
| Versatility | Fuels supported, maximum usable pizza size, and whether it cooks anything other than pizza. |
| Value | At its real price, against the alternative we would actually recommend instead. Support and spares count here. |
What each score means
| 5 | Best in class. We would struggle to name something that does this better at any price. |
| 4 | Strong. Does the job well with a caveat worth knowing but not worth avoiding it for. |
| 3 | Adequate. Works, with a real compromise you will notice every time you cook. |
| 2 | A defect. Something here would stop us recommending the oven for this purpose. |
| 1 | Fails at it. Do not buy this oven if this dimension matters to you. |
Half points are used. The overall is the arithmetic mean of the six, rounded to one decimal - no separate editorial number, no hidden weighting. A gate blocks publication if the overall does not equal that mean.
Three rules we hold ourselves to
A dimension that does not flatter an oven still gets scored. A built-in brick hearth scores low on Portability. That is a real fact about living with it, not a technicality, and quietly dropping a dimension a product would fail is the easiest way to inflate a mean without anyone noticing.
Price only enters through Value. Elsewhere we score what the oven does. Otherwise a cheap oven gets flattered on build quality for being cheap, and a genuinely excellent expensive one gets marked down for its price twice.
Certification is evidence, not points. Absence from a register does not prove absence of certification - any accredited body can issue to the same standards, and we have been corrected twice for treating those as the same claim. What we found is published on our certifications page, dated and checkable.
Where this leaves the existing scores: re-scored, 12 August 2026
Every rated review has now been re-scored against the six dimensions above. Sixteen pages, all six dimensions each, overall recalculated as the mean. Here is what changed, because publishing the new numbers without publishing the movement would be the same evasion in a new coat.
| Before | After | |
| Range | 3.5 to 4.2 | 2.8 to 4.2 |
| Spread | 0.7 | 1.4 |
| Reviews scoring below 3.5 | 0 | 2 |
| Distinct sub-score dimensions | 45 | 6 |
The biggest falls are the ovens where Value now has to carry what ownership actually costs. The BIG HORN falls from 3.7 to 2.8: at $150 it genuinely reaches 1,110F, and everything around that is hard work - a fire that will not hold, a door handle that spins when hot and cannot be tightened, gas sold separately. The Forno Venetzia Pronto 500 goes 3.8 to 3.1 on an 800F ceiling and a 52-minute preheat at $1,699.
Some went up, which matters just as much. The Gozney Dome rises to 4.2 and the Breville Pizzaiolo to 3.9, both because the old ad-hoc dimensions never credited what they are genuinely best at - build and temperature control respectively. A rubric that only ever lowers scores is a different kind of dishonest.
We no longer rate ovens you cannot buy
A star rating answers exactly one question: should I buy this? For a discontinued oven that question has no answer, so forcing one produced our two lowest scores on products nobody can purchase - a 2.2 on the Ooni Fyra 12 and a 3.4 on the Karu 16.
Those ratings are gone. Discontinued reviews keep everything that is actually useful to someone who lands on them: what the oven was like, why it was retired, what to buy instead, and whether a used one is worth the risk. They no longer carry a number pretending to be purchase advice.
We considered the other fix - a minimum score of 3.5 - and rejected it. It would have inflated a defunct pellet oven with a known fuel-feed defect to look like a recommendation, which is the pattern this whole page exists to disown. The honest version of that instinct is to be careful about what we RATE, not about where the number is allowed to stop.
A gate blocks publication if any overall stops equalling the mean of its own sub-scores, and a second one now checks that every review uses these six dimensions and no others. Sixteen of sixteen conform.
One consequence worth naming: the graphics have not caught up. Our Roccbox card still shows 4.1 against a page that now says 4.0, because nothing can read a raster and a picture does not know its article changed. Those are being regenerated, and until they are, the page is the authority.
Frequently asked questions
How is the overall score calculated?
It is the arithmetic mean of the sub-scores, rounded to one decimal place, and nothing else. There is no separate editorial number laid on top and no weighting we do not show you. A script checks this on every publish: if the overall does not equal the mean of the sub-scores beneath it, the page does not ship.
Why did your old scores all sit between 3.5 and 4.2?
Because they were not produced by a rubric. Sixteen reviews used forty-five differently-named sub-score dimensions between them, so no two ovens were measured against the same thing, and the resulting numbers clustered in a narrow band that made everything look worth buying. That is the standard affiliate pattern and we are not defending it.
Can an oven score below 3?
Yes. Under the old approach effectively nothing did - 4% of sub-scores fell below 3.0 and no overall did at all. A 2 means a real defect that would stop us recommending it, and the BIG HORN sits at 2.8 today for exactly that reason. There is no minimum score. What there is instead is a rule about what gets rated at all: we do not put a number on an oven you cannot buy.
Does certification affect the score?
No. Absence from a certification register does not prove absence of certification, so awarding points for a certificate would punish a manufacturer for the limits of our search rather than for their product. Certification is published as dated evidence on our certifications page, alongside the review rather than inside the number.
Does price affect the score?
Only through the Value dimension, and there it is decisive. Everywhere else we score what the oven does, not what it costs - otherwise a cheap oven gets flattered on build quality and an expensive one gets punished for being good. Value asks a separate question: at this price, against the alternative we would actually recommend, is this the right purchase?
Do affiliate relationships influence your ratings?
No, and the structure is designed so you do not have to take that on trust. The overall is a mechanical mean of published sub-scores, the sub-scores are defined against fixed bands on this page, and a gate blocks publication if the arithmetic does not hold. Where we cannot verify a manufacturer's figure we label it estimated rather than repeating it as a spec.
Are the current scores re-derived under this rubric?
Yes - all sixteen were re-scored on 12 August 2026, and the movement is published on this page rather than applied quietly. The rubric was published BEFORE the re-scoring, so the standard was visible while we still had every incentive to bend it. A day later we removed the ratings from two discontinued ovens, which is why the published range is now 2.8 to 4.2 across fourteen products you can actually buy.
Why six dimensions rather than tailoring them per oven?
Because tailored dimensions cannot be compared. If one oven is scored on Portability and another on Indoor Practicality, their overalls are means of different things and putting them side by side is meaningless. Fixed dimensions are what makes a score a comparison rather than a description.
What if a dimension does not apply to an oven?
It still gets scored, because the absence is information. A built-in brick oven scores low on Portability and that is a real fact about living with it, not a technicality. What we do not do is quietly drop a dimension an oven would fail, which would inflate the mean.
How do you handle a discontinued oven?
Performance dimensions are scored as measured - the oven cooks how it cooks. Value carries the consequence, because no warranty, no support and no first-party spares are a real cost to a buyer today. That is why our discontinued reviews carry a Value score well below their bake scores.
