In [[heraldry]], a '''bar''' is an [[Ordinary (heraldry)|ordinary]] consisting of a horizontal band across the shield.
A single bar placed across the top of the [[field (heraldry)|field]] is called a
'''[[chief (heraldry)|chief]] '''. A single bar placed over the center of the [[field (heraldry)|field]] is a '''[[fess]] '''. A division of the field by many bars — often six or eight — is a '' '[[barry (heraldry)|barry]]'''.
Thin bars are termed barrulets. A still thinner bar is known as a
cotise, which usually appear borne on each side of a fess. The fess is then described as " cotised."
The "closet" is described as a band of the thickness between a bar and a barrulet, but is rarely found.
A barry design consisting of ten or more bars is called barruly or burely instead.
