In the [[United Kingdom]], a commonly cited "standard" rate was 1,000 ens per hour, although actual compositors' output varied widely. Many workers fell short of this figure, while skilled workers were known to set 2,000–3,000 ens per hour, and late-1900s typesetting competitions often saw participants reach a corrected rate of 4,000 ens per hour. After the introduction of the [[Linotype machine|Linotype]] typesetters frequently reached rates of at least 6,000 ens per hour.<ref name="gaskell">{{cite book |last1=Gaskell |first1=Philip |title=A New Introduction to Bibliography}}</ref>
