How to Know What Size Air Fryer Is Best

To choose the ideal size for you, consider the following:

• Number of People: How many people do you typically cook for?
• Dish Types: Would you like to cook one item at a time (e.g. a serving of French fries) or a whole meal (like a lasagne), or a combination of items at the same time (like salmon with roast potatoes)?
• Counter Space: How much space do you have available in your kitchen?
• Usage Frequency: How often will you use the air fryer – daily or just occasionally?
• One basket or two: Would you prefer one larger compartment – or a dual air fryer with two baskets or drawers?

How Air Fryer Sizes Are Measured?

Air fryers are usually measured by their capacity. In the UK and Europe, this is generally measured in litres.

• Small air fryers (2 litres): ideal for individuals or couples.
• Medium air fryers (3-5 litres): suitable for families of 3 to 4.
• Large Air Fryers (6 litres) or more: (perfect for large families or entertaining). The capacity indicates how much food the air fryer can cook at once, so matching this to your typical meal sizes is a good idea.

Air Fryers for Large Families

For large families or households that entertain frequently, 6 litre air fryers or larger, are ideal. These models can accommodate whole chickens, large batches of frozen fries, or multiple servings of food at once. Look for models with multiple racks or extra-large baskets to maximize cooking space.
