The catch
Ninja Foodi Digital Air Fry Oven
The eight-mode list contains no dedicated Pizza preset.
Side by side
The SP101 brings a nine-slice toast layout, a 13-inch pizza claim and Keep Warm mode. If six slices and a 12-inch pizza are enough for you and you want a dedicated Pizza preset, the SP151 is the better pick.
Before you buy
Your breakfast exceeding one SP151 load is when nine versus six slices matters.
Where this comes from
Stated standard-slice counts go into (9 - 6) / 6 = 50%, which does not predict browning uniformity.
The catch
The eight-mode list contains no dedicated Pizza preset.
The catch
Six toast slices and a 12-inch pizza are where advertised capacity drops to.

Ninja SP101 and SP151 are compared here on toast count, pizza diameter, Keep Warm against Pizza mode, and the cooldown that flip-up storage requires.
a pizza preset, or larger flat batches
Which one fits
Six slices is what SP151 advertises, against nine for SP101.
A dedicated Pizza mode should not be assumed to enlarge SP151's 12-inch capacity.
A dedicated Pizza setting is on SP151. SP101 can bake pizza without that named preset.
Either storage mechanism needs the oven to cool first. Instant extra prep space is not possible.
In practice
Your breakfast exceeding one SP151 load is when nine versus six slices matters.
Stated standard-slice counts go into (9 - 6) / 6 = 50%, which does not predict browning uniformity.
SP101's advertised limit accommodates a full 13-inch pizza, while SP151's does not.
Pizza capacity is stated as 13-inch and 12-inch by the manufacturers. Pan rims and crust shape still need to be checked.
Both advertise eight functions, yet the difference comes down to a Keep Warm setting versus a Pizza setting.
Keep Warm is on the SP101 mode list. Pizza is on SP151's list in its place.

Ninja, SP101
This shallow eight-mode air-fry oven takes a 13-inch pizza or nine toast slices. When it has cooled, it pivots upright and the counter is clear again.

Ninja, SP151
Once cool, this shallow eight-mode oven tips up on end, and the counter space in front of the backsplash is yours again.
Spec by spec
| Spec | Ninja Foodi Digital Air Fry Oven | Ninja Flip Toaster Oven and Air Fryer | In practice |
|---|---|---|---|
| Advertised toast capacity | 9 slices | 6 slices | Three more standard-slice positions come with SP101. |
| Advertised pizza diameter | 13 inches | 12 inches | The SP151 advertised limit is exceeded by a 13-inch pizza. |
| Distinct mode in the eight-function set | Keep Warm | Pizza | Holding food is where SP101 leans. SP151 provides a dedicated pizza setting. |
| Storage mechanism | Flip up after cooling | Flip up after cooling | Neither frees up its cooking footprint right after a hot meal. |
Trade-offs
Change of plan
Go with Ninja Foodi Digital Air Fry Oven. That order can stay within one load thanks to the larger advertised flat-food layout of SP101.
Go with Ninja Flip Toaster Oven and Air Fryer. That stated use lines up more closely with its function selection.
Decision guide
Go with the SP101 for its nine-slice toast layout, 13-inch pizza claim and Keep Warm mode. The SP151 is for people who are fine with six slices and a 12-inch pizza and want a dedicated Pizza preset.
A low-profile layout is shared by both ovens. In this pairing the SP101's advertised toast and pizza capacities are the larger ones, which helps with flat batches even though the SP151 is the newer model.
The two eight-function labels hide a practical trade. The SP101 provides Keep Warm, the SP151 provides Pizza. Counting presets alone will not tell you which fits better.
Between uses, the hinge can win back counter area. Clearance requirements during cooking stay the same, and you cannot flip a hot oven away right after dinner. Measure the operating position and the upright position both.
By the numbers
What we found across the countertop ovens we compare, plus the checked facts behind each finding.

How we countedThe count uses each product's current fit ratings for “Stores upright after cooking”, “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.
