The catch
Breville Smart Oven Air Fryer
The wider BOV900 takes 9 by 13-inch pans, which this model cannot.
Side by side
For a 13-inch pizza and regular family cooking, go with the BOV860. The BOV900 is worth the extra space when 9 by 13-inch pans, two racks or dehydrating come up often.

The catch
With a 21.4-inch body width and required ventilation, it needs a counter spot picked in advance.

Pan width, number of programs and how much counter you give up set these two air-fry Smart Ovens apart.
This one comes down to interior and functions first, then to the limits of your own setup.
Day to day
If you plan to move a favorite tray-bake recipe onto the counter, measure the pan you really use, handles included. BOV900 is documented to have room for most nine-by-thirteen-inch pans, and its included roasting pan is in that size class. The roasting pan supplied with BOV860 measures eight-and-a-quarter-by-twelve-inch. Pick BOV900 when that larger rectangular bakeware is a firm requirement, and confirm your own pan fits instead of leaning on the pizza diameter.
Between the official sizes of the included pans and the BOV900 fit statement, there is enough to do a concrete cookware check. A rating for a thirteen-inch round pizza says nothing certain about whether a thirteen-inch rectangular pan with handles will go into BOV860.
On top of the everyday cooking functions both ovens share, BOV900 has dedicated Proof and Dehydrate modes. These can keep the appliance busy between meals, although they tie up its single chamber while they run. It makes sense if you can fit dough or drying around dinner. When the oven mostly air fries, bakes and reheats, BOV860 already handles those jobs, and these extra modes give you no reason to move up a size.
According to the official lists, BOV860 has eleven functions and BOV900 has thirteen, and Proof and Dehydrate account for the difference. No assumptions are made about operating duration, temperature interchangeability or parallel cooking capability.
Which one fits
Breville Smart Oven Air Fryer lists “13-inch pizza” for large pan, while Breville Smart Oven Air Fryer Pro lists “9 by 13-inch pan”. This is how much food or material fits in one usable batch, which tells you more than the headline size.
Breville Smart Oven Air Fryer has its own shade controls, and the rack is wide enough for the toast a household usually makes at once.
A standard frozen or fresh pizza goes in as is, with no trimming or folding.
Moving hot air around speeds up browning and narrows temperature differences.
A roast fits, with enough height and pan area that it does not crowd the upper elements.
There is a dedicated broil setting, and a rack position near the top sits close to the elements.

Breville, BOV860BSS1BUS1
This mid-size Breville offers eleven programs, a cavity that takes a 13-inch pizza and forceful super-convection airflow.

Breville, BOV900BSSUSC
Thirteen modes, including slow cook and dehydrate, come with a one-cubic-foot cavity that has room for broad pans and strong convection.
Spec by spec
| Spec | Breville Smart Oven Air Fryer | Breville Smart Oven Air Fryer Pro | In practice |
|---|---|---|---|
| Interior | 0.8 cubic foot | 1 cubic foot | How the unit is built determines what fits in it, what stays apart and how loading and emptying work. |
| Functions | Eleven | Thirteen | How many steps fall to you and how much happens automatically both come down to this. |
| Large pan | 13-inch pizza | 9 by 13-inch pan | What counts is how much food or material fits in one usable batch, and that says more than the headline size does. |
