Air fryer capacity is usually shown in litres, but litres do not tell you whether tonight’s food will sit in one useful layer. Start with the portions and shapes you cook most often, then use the litre figure to narrow the field.
For one person: keep it easy to live with
A compact single drawer can suit one person when most meals are a protein, a side or reheated leftovers. The advantage is not only a smaller appliance: a smaller basket is usually easier to carry to the sink and less awkward to store.
Think about your largest regular ingredient. If you often cook a long fillet, several skewers or a full layer of vegetables, check the basket’s internal shape before choosing the smallest model.
For two people: basket shape starts to matter
Two portions need enough base area to avoid constant stacking. A wide basket can be more useful than a deeper basket with the same advertised capacity, especially for crumbed food, vegetables or anything you want to brown evenly.
A medium single drawer is the simple option when both people eat the same meal. Dual drawers become more useful when you regularly need different temperatures or finish times.
For three or four people: plan the whole meal
Larger households should decide whether the air fryer is cooking one component or replacing more of the oven. A roomy single basket works well for one large batch. Two zones can handle protein and vegetables separately, but each zone may be narrower than expected.
If you would still need a second batch for most dinners, a larger model may save time. If you mainly use it for chips or one side dish, an oversized machine may just occupy more bench space.
Do not choose by litres alone
Manufacturers measure capacity differently, so compare internal basket dimensions where they are published. A square basket, a rounded basket and two narrow drawers can behave very differently even when the total capacity looks similar.
Also check the usable height. Tall capacity is helpful for some foods, but food crowded in layers may need more shaking or turning than food spread across a wider base.
Measure the space around it
Measure the appliance, the clearance recommended by its manufacturer and the extra depth needed to pull the drawer out safely. Check where hot air vents and where the basket will sit when you serve or clean it.
A model that stays on the bench should fit without blocking cupboards or the main preparation area. A model stored away should be light and compact enough that you will actually take it out.
A quick size decision
Choose compact when you normally cook one or two portions and value easy storage. Move up when you regularly cook three or four portions in one batch. Choose dual zones for genuinely different foods—not simply because two drawers sound more capable.
Before paying, inspect the exact model’s basket dimensions, included parts and clearance instructions on the manufacturer’s page. Those details are more reliable than a household-size label alone.
