PROBLEM TO BE SOLVED: To provide a method for obtaining the ejection amount from a droplet ejection head, a method for determining appropriate voltage, and a droplet ejection device which accurately obtains the ejection amount or determines appropriate drive voltage according to a change in ejection rate corresponding to the number of nozzles simultaneously driven. SOLUTION: The method for obtaining the ejection amount from a droplet ejection head includes an ejection step of simultaneously driving one or more ejection nozzles 21 by the standard drive voltage from a head driver, an ejection amount measuring step of measuring the ejection amounts ejected from the one or more ejection nozzles 21 in the ejection step, an ejection amount correcting step of correcting the measured ejection amounts from the one or more ejection nozzles 21 using correction values according to the number of ejection nozzles 21 simultaneously driven in the ejection step, and an ejection amount obtaining step of obtaining the corrected ejection amounts from the one or more ejection nozzles 21.
