Your recommended size
We recommend an air fryer between 4L and 5L.
For two people and simple meals (single-dish or ready-made), 4L–5L gives you enough capacity for two portions at once without going oversized. It’s a practical middle ground.

How to choose the right air fryer size
Air fryer capacity is usually given in litres (L). It refers to the basket volume—how much food you can fit in one go. More people or bigger meals mean you need more litres, or you’ll cook in batches.
By household size
One person: 2L–4L is enough for snacks and simple meals; 4L–5L if you cook full meals. Two people: 4L–6L for regular meals. Three to four: 5L–7L for full meals. Four or more or batch cooking: 6L–10L or a dual-drawer model.
By cooking habit
Snacks only (fries, nuggets, reheating): smaller capacities are fine. Simple meals (single portions, ready meals): 4L–5L often enough. Full meals (meat + sides, family dinners): aim for 5L–7L for 3–4 people. Batch cooking or meal prep: 7L+ or dual drawers.
Compact vs family vs large
Compact (roughly 2L–4L): single or couple, light use, small kitchens. Family (5L–7L): small families, full meals, most versatile. Large (7L+): big families, batch cooking, or dual-drawer for cooking two things at once.
Limited counter space
If space is tight, choose a smaller model within the recommended range or a design that fits under cupboards. See our guide on the best air fryer for a small kitchen. You may cook in two batches for larger meals; we’ll note that in the calculator result.

Frequently asked questions
For two people cooking regular meals (not just snacks), a 4L–6L air fryer is usually enough. If you often cook full meals or multiple items, aim for 5L–6L. For snacks and light use only, 3L–4L can work.
It depends on the family size and what you cook. For a family of 3–4 eating full meals, 5L is the lower end; 5.5L–7L gives more flexibility and avoids cooking in batches. For 4+ people or batch cooking, consider 6L–8L or a dual-drawer model.
A whole chicken typically needs a basket capacity of at least 5L–6L, and often 6L+ for a larger bird. Check the manufacturer’s guidance for your model. Many 5L units can fit a small chicken; for regular whole chickens, 6L or more is safer.
Dual-drawer models let you cook two foods at different times and temperatures, which is useful for families cooking multiple items (e.g. chips and chicken). They take more counter space. For smaller families or single-dish meals, a single large basket (6L–7L) is often enough and simpler.
Smaller baskets use less energy per cycle because they heat less volume. For the same meal, a 4L model will generally use less energy than a 8L one. If you often fill a large basket, the difference per portion is smaller. Choosing the right size for your typical use avoids wasting energy on an oversized unit.
For batch cooking (meal prep, cooking for several days, or large families), aim for 6L–10L or a dual-drawer model with 7L+ total capacity. Single baskets of 7L–9L work well; dual drawers add flexibility for different foods at once.
