What Does an Air Fryer Quart Rating Actually Mean?
The quart figure measures total basket volume, not the single-layer surface area that determines whether food crisps or steams.
An air fryer's quart rating measures the basket's total volume, not the single-layer surface area that actually determines whether food crisps or steams. A 5.8-qt basket that's deep and narrow can hold less usable cooking area than a 4-qt basket that's wide and shallow. The 'fits a whole chicken' claim on 5.8-qt baskets generally assumes a small bird (under 4-5 lb) laid on its side — check your basket's actual interior diameter before assuming a standard roaster fits upright.
