The catch
Breville Compact Smart Oven
You will not find a convection fan or an air-fry setting.
Side by side
A twelve-inch pizza is the reason to move up to the Compact BOV650. When compact placement comes first, the Mini BOV450 suits four-slice toast and smaller food.
Before you buy
Compared with an 11-inch pizza, a 12-inch pizza covers about 19% more area.
Where this comes from
(12² / 11² - 1) × 100 = 19.0%. That figure is geometric pizza area.
The catch

The catch
In practice, an 11-inch pizza is as big as it gets.

The smaller oven format, or a twelve-inch pizza
Which one fits
An 11-inch pizza is the rating for BOV450.
Four slices is what both advertise.
A convection air-fry system is absent from both.
Because neither model has a convection fan, a different oven is the way to go for that cooking method.
In practice
Compared with an 11-inch pizza, a 12-inch pizza covers about 19% more area.
(12² / 11² - 1) × 100 = 19.0%. That figure is geometric pizza area.
Neither raises the stated four-slice breakfast batch, so BOV650 matters more for its larger pizza and pan fit than for how much toast it makes.
0 slices = 4 - 4.
No reason to upgrade comes from the number of modes.
8 - 8 = 0 functions, and neither oven has a fan.

Breville, BOV650XL
The familiar LCD and Element IQ controls carry over to this four-slice Breville, in a narrower eight-function body.

Breville, BOV450XL
The smallest Breville oven handles toast, bagels, pizza and baking, and its control panel is unusually tidy.

Go with Breville Compact Smart Oven. An 11-inch pizza is the rating for BOV450.
Decision guide
The Compact BOV650 is the upgrade for a twelve-inch pizza. Four-slice toast and smaller food suit the Mini BOV450, especially when a compact spot on the counter matters most.
Do not assume a 12-inch pizza will fit an oven rated for 11 inches. The larger Compact fixes that fit problem outright, before cooking functions even come into the picture.
Four toast slices is the rating for each. For someone buying only for breakfast, the Compact lists no extra slices.
You will find no convection fan and no dedicated air-fry setting on either. If fast basket crisping is what you want, look at a different product family.
By the numbers
What we found across the countertop ovens we compare, plus the checked facts behind each finding.
Only 8 of the 26 models checked meet every need here: “Takes up little space on a crowded counter”, “Same toast result every busy morning”, and “A 12-inch pizza or anything larger fits”.
8 models fit, out of 26 checkedBreville Compact Smart Oven lists 12 in for listed pizza size, 9% more than the 11 in on Breville Mini Smart Oven.
How we countedThe count uses each product's current fit ratings for “Takes up little space on a crowded counter”, “Same toast result every busy morning”, and “A 12-inch pizza or anything larger fits”. A need with no documented match is not counted.
How we calculatedFigures are the largest round pizza the maker explicitly says fits the cavity. Pan shape and rack clearance still play a part. For context, 16 of 26 models publish comparable figures.
