Claim 15:
16. A method of forming a fluid ejection die, comprising:
arranging a plurality of nozzles in a plurality of nozzle columns, the plurality of nozzle columns distributed across a width of the fluid ejection die in a staggered manner,
wherein nozzles of each respective nozzle column of the plurality of nozzle columns are spaced apart along a length of the fluid ejection die,
wherein the plurality of nozzle columns includes a first pair of neighboring nozzle columns, the neighboring nozzle columns spaced by a first distance across the width, and
wherein the plurality of nozzle columns includes a second pair of neighboring nozzle columns, the neighboring nozzle columns spaced by a second distance across the width, the second distance being larger than the first distance; and
fluidically coupling an array of fluid feed holes to respective nozzles of the plurality of nozzles, the array of fluid feed holes including a respective first fluid feed hole and a respective second fluid feed hole fluidically coupled to each respective nozzle of the plurality of nozzles, wherein the respective first fluid feed hole and the respective second fluid feed hole are connected in parallel.
