Air Fryer Size Calculator
Enter how many people you usually cook for and tick what applies. The calculator gives a capacity range in quarts and the style that fits: one basket, two baskets or an oven-style fryer with racks. The bands follow Cosori's published size table and Wirecutter's 4 to 5 quart sweet spot for small households; they are a starting point, because basket shape changes how much really fits. Everything runs in your browser; nothing is uploaded or stored.

How it works
Air fryers cook best when food sits in a single layer with air moving around it, so the right size is the one that fits your usual meal in one layer without a second round. The calculator starts from household size:
| People | Capacity | Basis |
|---|---|---|
| 1 | 2 to 4 qt | compact baskets; 5 qt if you batch-cook |
| 2 | 4 to 6 qt | Cosori: 5 qt is plenty for one or two |
| 3 | 5 to 6.5 qt | Cosori: 6.0 to 6.5 qt for two to three |
| 4 to 5 | 6.5 qt single or 9 qt dual | Cosori: three to five people |
| 5+ | 9 qt dual or larger | Cosori: five or more, or frequent hosting |
Then it adjusts: meal prep and hosting move you up one band, a whole chicken sets a 6 quart floor, and cooking a main and a side together points to a dual-basket model. These adjustments are this site's rules of thumb, not a manufacturer standard.
What it does not cover
- Basket shape. A square basket holds more in one layer than a round basket with the same quart rating; compare basket dimensions where the maker lists them.
- Counter fit. Measure depth and the height under your cabinets, and check the manual's clearance. More in what size air fryer you need.
- Wattage and circuits: larger fryers draw more power; check your outlet before running two big appliances at once.

Frequently asked questions
What size air fryer do I need for one person?
About 2 to 4 quarts covers one person cooking sides and small portions. Go to about 5 quarts if you cook full meals or batches. Cosori describes a 5 quart basket as plenty for one or two people.
What size air fryer for a family of four?
About 6.5 quarts in a single basket, or a dual-basket fryer of around 8 to 9 quarts if you want to cook a main and a side at once. Cosori lists a 6.5 quart single basket or 9 quart dual basket for three to five people.
Is a bigger air fryer always better?
No. A bigger basket takes more counter space and, on some models, longer to heat. What matters is fitting food in a single layer for your usual meal. Size for the meals you cook most often, not the holiday feast.
Are quarts the same across brands?
Not in practice. Two fryers with the same quart rating can have different basket shapes, and a square basket usually holds more food in one layer than a round one of the same rating. Compare basket dimensions where the maker lists them.
Dual basket or one big basket?
Dual baskets let you cook two foods at different settings and finish together, but each basket is smaller, so a large item such as a whole chicken may not fit. One big basket suits large single items and big batches.
