[[File:Arms of John de Warenne, 6th Earl of Surrey (d.1304).svg|thumb|200px|''Chequy or and azure'', the famous mediaeval arms of [[William de Warenne, 5th Earl of Surrey|de Warenne, Earl of Surrey]], today quartered by the [[Duke of Norfolk]]. Effectively a field ''azure semée of chequers or'' with the first chequer placed in the [[Dexter and sinister|dexter]] chief]]
When divided by palewise and fesswise lines into a [[Check (pattern)|chequered pattern]], the field is ''chequy''. The [[coat of arms of Croatia]] ''Chequy gules and argent'' is a well known example of the red and white chequy.<ref>Carter, David E.; Stephens, Suzanna M. W.

James Parker cites the French term ''equipolle'' to mean chequy of nine, though mentions that this is identical to a ''cross quarter-pierced'' (strangely, this is blazoned as ''a [[Latin square]] chequy of nine'' in the arms of the [[Statistical Society of Canada]]).<ref>{{Cite web |url= http://www.ssc.ca/main/about/history/arms_e.html |title=Letters Patent Confering the SSC Arms |access-date=2010-02-12 |archive-url= https://web.archive.org/web/20091217193713/http://www.ssc.ca/main/about/history/arms_e.html |archive-date=2009-12-17 |url-status=dead}}</ref> He also gives the arms of Prospect as an unusual example of chequy, ''Chequy in perspective argent and sable'';<ref>{{harvp|Parker|Gough|1894|p=[https://archive.org/details/aglossarytermsu08parkgoog/page/n137 104]}}</ref> which must be distinguished from cubes as a charge.<ref>{{cite web |url= https://www.wcsim.co.uk/about/our-coat-arms |title=Our Coat of Arms |website=Worshipful Company of Scientific Instrument Makers}}{{Dead link|date=April 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Chequy is not "fanciable"; that is, the lines of chequy cannot be modified by [[Line (heraldry)|lines of partition]].<ref>{{cite journal |url= http://www.grsampson.net/AHtc.html |title=Historical Trends in Choice of Ordinaries and Charges |first=G.
