In 2016 the [[Kieldrecht Lock]] in the [[Port of Antwerp]] in Belgium took over the title of the world's largest lock from the [[Berendrecht Lock]] in the same port and still has the title for largest volume. In 2022 the [[IJmuiden sea lock]] serving the [[Port of Amsterdam]] became the world's largest lock by surface area. The lock is {{convert|500|m|ft|abbr=on}} long, {{convert|70|m|ft|abbr=on}} wide and has sliding lock gates creating a usable depth of {{convert|18|m|abbr=on}}. 

The size of locks cannot be compared without considering the difference in water level that they are designed to operate under. For example, the [[Bollène]] lock on the [[River Rhône]] has a fall of at least {{convert|23|m|abbr=on}}, the Leerstetten, Eckersmühlen and Hilpoltstein locks on the [[Rhine–Main–Danube Canal]] have a fall of {{convert|24.67|m|abbr=on}}, each and the [[Oskemen]] Lock on the [[Irtysh River]] in [[Kazakhstan]] has a drop of {{convert|42|m|abbr=on}}.<ref>{{cite web|url=http://www.waterwaysworld.com/latest.cgi?month=012008&start=20|title=Latest|publisher=Waterways World|access-date=2011-08-05|archive-date=2011-07-26|archive-url=https://web.archive.org/web/20110726045506/http://www.waterwaysworld.com/latest.cgi?month=012008&start=20|url-status=dead}}</ref>
