The bin height for Ninja's "Double Stack Hot Air Fryer, 7.6 L", model SL300EU, is built into a compact design where the two bins are stacked on top of each other. The overall height of the appliance is designed to fit under standard cabinets, but the exact height of the individual trays is not specified in the available sources.

However, it can be deduced that the overall height of the appliance, including the two bins, is relatively compact and designed to save counter space, as mentioned in descriptions of similar models.
