Abstract: In some examples, a fluid ejection device includes a support body, a multi-die assembly, and a fluid channel that extends through the support body from a first side to a second side adjacent the multi-die assembly. The multi-die assembly includes a plurality of fluid ejection dies to receive fluid from the fluid channel, where a first fluid ejection die of the plurality of fluid ejection dies is to dispense fluid of a first drop size, and a second fluid ejection die of the plurality of fluid ejection dies is to dispense fluid of a second drop size different from the first drop size.
