The catch
Breville Smart Oven Air Fryer Pro
A 21.4-inch-wide body means you must give up a stretch of counter for good.
Side by side
Breville Smart Oven Air Fryer Pro vs Ninja Flip compared: Taller oven jobs fit in Breville, and Ninja flips away when done
Quick verdict
The Breville Smart Oven Air Fryer Pro makes sense if it will take over substantial baking and roasting from your main oven. Ninja Flip makes sense if your regular jobs are flatter foods and you want counter space back after cooking. Breville fits a 13-inch pizza and most 9-by-13-inch pans, whereas Ninja's 12-inch pizza capacity comes in a flip-up design.
Before you buy
Why, and what it costs you
Pizza area grows about 17% with one extra inch
Against 113 square inches for a 12-inch circle, a 13-inch circle has around 133 square inches of area. That is a difference of about 20 square inches, and it says nothing about how many people dinner will feed.
Where this comes from
Circle area is π × radius². The ratio 13² ÷ 12² is 1.174, which makes the increase 17.4%. It assumes circular pizzas at the stated diameters.
The catch

In practice
Differences you will notice
Pizza area grows about 17% with one extra inch
Against 113 square inches for a 12-inch circle, a 13-inch circle has around 133 square inches of area. That is a difference of about 20 square inches, and it says nothing about how many people dinner will feed.
How we worked this out
Circle area is π × radius². The ratio 13² ÷ 12² is 1.174, which makes the increase 17.4%. It assumes circular pizzas at the stated diameters.
Ninja's storage advantage leaves the cooking space requirement unchanged
Cooking requires the oven to sit in its operating position. Flipping it away afterward helps on a shared counter, yet heat clearance is still needed while it is in use.
How we worked this out
This inference comes from the manufacturer's flip-up storage design. The comparison claims no cross-model percentage for the operating footprint.
Your usual pan can be a firm limit
Breville states outright that it supports most pans of that size, which matters if your regular recipe relies on a 9-by-13-inch pan. You still need to check the pan's actual outer dimensions.
How we worked this out
The exact BOV900 record for Breville lists most 9-by-13-inch pans. Because pan labels may leave out handles and lips, fit is not guaranteed for every dish.

Spec by spec
Where they really differ
| Spec | Breville Smart Oven Air Fryer Pro | Ninja Flip Toaster Oven & Air Fryer | In practice |
|---|---|---|---|
| Published pizza size | 13 inches | 12 inches | A slightly larger circular pizza is possible on Breville. |
| Baking-pan fit | Most9 ×13-inch pans | Check the shallow cavity against your dish | For familiar larger bakeware, Breville is the firmer place to start. |
| Interior emphasis | One-cubic-foot oven cavity | Low-profile flip-up oven | Shape counts for more than a comparison of incompatible capacity units. |
| Storage | Remains in its cooking position | Flips upright after cooling | Between meals, Ninja can hand the counter space back. |
| Modes | 13 including proofing and slow cooking | Eight cooking modes | Additional modes only count when they take over work you would otherwise do somewhere else. |
| Included cooking equipment | Two oven racks, 13-inch pizza pan and roasting pan | Wire rack, sheet pan and air-fry basket | Look at which accessories your regular meals call for. |
Trade-offs
What each pick costs you
With Breville Smart Oven Air Fryer Pro
- Cleanup of the racks and mesh basket takes more effort than a removable drawer, and a compact fryer feels quicker for small batches.
With Ninja Flip Toaster Oven & Air Fryer
- Drawer fryers generally crisp more evenly, and the removable parts here are not dishwasher-safe.
Decision guide
How to decide
Breville is for the dishes and cookware you want to put inside. Ninja is for when the counter has other work to do after dinner.
Factor in your cookware measurements
Because Breville publishes support for most 9-by-13-inch pans, it is relevant to cooks who already own familiar baking dishes. Handles and rims can push the outer dimensions beyond the named pan size. Measure the whole dish and its height, and leave the space around the food that airflow requires.
The storage savings come after cooking
On a counter that does many jobs, Ninja's flip-up design is valuable, yet the oven still needs working room while it is hot and laid flat for cooking. Consider where the cord runs, what sits behind it and whether you can flip it comfortably once it has cooled. The storage convenience should fit your real kitchen routine.
Pick the extra modes you will really use
Alongside its oven and air-fry modes, Breville has dedicated options such as proofing and slow cooking. They can make it a useful second oven and not merely a snack machine. When your main oven already covers those jobs, Ninja's more focused format may be easier to justify and to find room for.
What this page can’t tell you
- The pizza-area calculations compare circular size only. They do not cover servings or cooking quality.
- The flip-up storage claim says nothing about the footprint needed during operation.
