🧺 Air Fryer Capacity Calculator
Tell it your household size and how you cook, and see the air-fryer quart and litre range that fits — from a compact single-serve basket to a dual-basket family model.
🧺 Recommended size
For 3 people cooking full meals, a 5-6 qt (mid-size) air fryer fits best.
Buy the size you'll actually use
The most common air-fryer regret is size — too small to cook a family meal in one go, or too big for the counter and the couple who bought it. Capacity is about how much food fits in a single layer, so the right number depends on both how many people you feed and how you like to cook.
Once you have a size, use the Cooking Time Calculator to dial in temperatures and the Energy Cost Calculator to see what running it will cost.
❓ Frequently Asked Questions
What size air fryer do I actually need?
As a rule of thumb: 2-4 quarts suits one or two people cooking sides and snacks, 5-6 quarts handles full meals for a family of three or four, and 7-10 quarts (or a dual-basket model) is best for five or more or for batch cooking. This tool picks the range from your inputs.
Quarts or litres — what's the difference?
They measure the same thing, just in different units — one quart is about 0.95 litres. US listings use quarts; UK and EU listings use litres. The calculator shows both so you can shop either way.
Is a bigger air fryer always better?
Not necessarily. A larger basket cooks more at once but takes up more counter space, uses a bit more energy, and can leave small portions rattling around. Match the size to how you really cook — that's what this calculator is for.
When should I choose a dual-basket model?
Dual-basket air fryers let you cook two foods at different settings and finish them together — great for families and full meals. The tool suggests one once your needs reach the 7-10 quart family tier.
