By Tim McGregor · Updated 11 September 2026
Choose around the meals you make and the space needed to use the fryer. A narrow body can still be deep, and a capacity in litres does not tell you whether your usual food fits in one layer.

Top 3 air fryers compared
Choose by the job and trade-offs below. Amazon links open product searches: confirm the exact model, bundle and seller on the selected offer.
Ninja Double Stack XL SL400UK
Ninja Double Stack XL divides 9.5 litres between two 4.75-litre drawers. The stacked layout reduces width, but its 47 cm body depth still needs checking against the worktop.
Benefits & things to consider
Consider it if
You want two drawers without a wide side-by-side body.
Main compromise
The body dimensions leave out the space needed to open and work with drawers.
Before ordering
Measure depth and drawer access, and check the installation clearances in the manual.

Russell Hobbs Satisfry Large Air Fryer
Russell Hobbs Satisfry Large 26510 is the single-basket starting point in this comparison. Its 5-litre rating is useful for identifying the model, but actual food shape matters when deciding portion size.
Benefits & things to consider
Consider it if
You usually cook one basket of food at a time.
Main compromise
One basket offers less separation than two drawers for different foods.
Before ordering
Confirm 26510 and compare the basket’s usable area with your usual meal.

Ninja CRISPi PRO 5-in-1 Glass Air Fryer Family Set AS090UKGN38
This Ninja CRISPi Pro Family Set uses a different glass-container format. Compare the exact included containers and storage space rather than treating all CRISPi packages as the same product.
Benefits & things to consider
Consider it if
You prefer the glass-container format and will use the supplied set.
Main compromise
Extra containers require storage and a place to handle them after cooking.
Before ordering
Match AS090UKGN38 and verify the container sizes and box contents with the seller.

How to choose air fryers
How big an air fryer do you need?
Start with a typical meal rather than a household-size label. Check the room for your usual pieces of food, whether you need separate cooking temperatures and whether you accept batches. Two drawers can separate foods, but splitting a total capacity also limits the space in each drawer.
Will it fit below the kitchen cupboards?
Mark the body footprint and then account for opening, loading and the manufacturer’s ventilation clearances. Double Stack’s listed body is 28 cm wide, 47 cm deep and 38.5 cm high. CRISPi needs somewhere to put its containers; those working areas are not captured by one appliance measurement.
Compare cleanup as part of the meal
List the basket or container, plates, racks and lids you would use for a normal dinner. Read which parts are dishwasher safe and how they should cool and be cleaned. We have not tested cooking evenness, cooking speed or washing effort, so programme counts are not performance scores.

Final verdict
Choose around the meals you make and the space needed to use the fryer. A narrow body can still be deep, and a capacity in litres does not tell you whether your usual food fits in one layer.
Use the shortlist to narrow your choice, then confirm the specific model and its main compromise in the table before ordering. A higher specification is useful only when it serves your routine.
