If you cook for one or two people, the ideal air fryer is the one that fits in your kitchen, cleans in a minute and doesn't force you to cook in several batches. This page helps you narrow down the size and avoid paying for capacity you won't use. The numbers are approximate: they change depending on the model and what you cook.

As a general guide, a small or medium-capacity basket handles dinner for two without overcrowding. What matters is not so much the litres advertised on the box as what fits in a single layer: food needs space for the air to circulate. If you often cook potatoes, chicken and vegetables at the same time, consider a somewhat larger size or a dual basket.

• It takes up little counter space and is easy to store in small apartments.
• It heats up quickly because the space to heat is small.
• It uses less energy per batch, although that depends on the model. See how much power an air fryer uses.
• It cleans up faster: fewer parts and less surface area.

• You often have guests over.
• You do batch cooking and cook for several days, as in the chicken breast for batch cooking recipe.
• You want to cook protein and a side at the same time without doing two batches.

1. That the basket or container fits in your sink and, if the manufacturer says so, in the dishwasher.
2. The free space around the appliance: it needs ventilation at the air outlet.
3. The height of the basket, if you want to cook pieces like thighs or a whole fish.
4. The accessories compatible with that size, in air fryer accessories.

As a rough guide, a small or medium size is enough for two people. The key is that the food fits in a single layer without overcrowding.

Usually not. For large pieces you need more capacity or an oven-style model; for thighs, wings or breasts it usually works.
