What size air fryer do I need for a family of four?

A 4 to 5 quart air fryer handles most meals for a family of four, though you may need to cook in batches for larger items. On a budget, most models are 2 to 4 quarts, which works well for one or two people or side dishes. If you regularly cook for four or more, consider stretching your budget slightly for a 5 to 6 quart model, or plan on cooking proteins and sides in separate batches.
