Examples include a fluid ejection device. The fluid ejection device includes a fluid ejection die with a die length and a die width, the fluid ejection die being coupled with a support structure having a fluid supply channel therethrough. The fluid ejection die includes a plurality of nozzles arranged in columns at die length positions along the die length and die width positions along the die width such that only one nozzle is positioned at each die length position. A fluid ejection chamber is coupled with each respective nozzle of the plurality of nozzles, and fluid feed hole fluidically coupled with the fluid supply channel and each respective ejection chamber.
