Main trade-off
Ninja Foodi Digital Air Fry Oven
No dedicated Pizza preset in the eight-mode list.
Head-to-head
Choose SP101 for its nine-slice toast layout, 13-inch pizza claim and Keep Warm mode. Choose SP151 when six slices and a 12-inch pizza are sufficient and you want a dedicated Pizza preset.
Before you choose
Nine versus six slices matters if your breakfast exceeds one SP151 load.
What this is based on
(9 - 6) / 6 = 50%. This uses stated standard-slice counts and does not predict browning uniformity.
Main trade-off
No dedicated Pizza preset in the eight-mode list.
Main trade-off
Advertised capacity falls to six toast slices and a 12-inch pizza.


Compare Ninja SP101 and SP151 by toast count, pizza diameter, Keep Warm versus Pizza mode and the cooldown needed for flip-up storage.
larger flat batches or a pizza preset
Winner by situation
SP101 advertises nine slices while SP151 advertises six.
Do not assume a dedicated Pizza mode enlarges SP151's 12-inch capacity.
SP151 has a dedicated Pizza setting. SP101 can bake pizza without that named preset.
Both storage mechanisms require the oven to cool first. This cannot provide instant extra prep space.
What matters in practice
Nine versus six slices matters if your breakfast exceeds one SP151 load.
(9 - 6) / 6 = 50%. This uses stated standard-slice counts and does not predict browning uniformity.
A full 13-inch pizza fits within SP101's advertised limit and exceeds SP151's.
The manufacturers state 13-inch and 12-inch pizza capacity. Actual pan rims and crust shape still need checking.
The difference is a Keep Warm setting versus a Pizza setting, even though both advertise eight functions.
The SP101 mode list includes Keep Warm. SP151's list includes Pizza instead.

Ninja, SP101

Ninja, SP151
A shallow eight-mode oven pivots upright after cooling, freeing the counter in front of the backsplash.
Meaningful differences
| What changes | Ninja Foodi Digital Air Fry Oven | Ninja Flip Toaster Oven and Air Fryer | Why it matters |
|---|---|---|---|
| Advertised toast capacity | 9 slices | 6 slices | SP101 offers three additional standard-slice positions. |
| Advertised pizza diameter | 13 inches | 12 inches | A 13-inch pizza exceeds the SP151 advertised limit. |
| Distinct mode in the eight-function set | Keep Warm | Pizza | SP101 favors holding food. SP151 provides a dedicated pizza setting. |
| Storage mechanism | Flip up after cooling | Flip up after cooling | Neither frees its cooking footprint immediately after a hot meal. |
What you give up
Recommendation switch
Choose Ninja Foodi Digital Air Fry Oven. SP101's larger advertised flat-food layout can keep that order within one load.
Choose Ninja Flip Toaster Oven and Air Fryer. Its function selection matches that stated use more closely.
What matters in practice
Both ovens use a low-profile layout. SP101's advertised toast and pizza capacities are larger in this pairing, which is useful for flat batches even though SP151 is the newer model.
The two eight-function labels conceal a practical exchange. SP101 supplies Keep Warm, while SP151 supplies Pizza. The preset count alone does not identify the better fit.
The hinge can reclaim counter area between uses. It does not reduce clearance requirements during cooking or let you move a hot oven straight after dinner. Measure both the operating and upright positions.
