The virgate (Medieval Latin: virgāta) or yardland (Middle English: yardland) was a unit of land area measurement used in medieval England, typically outside the Danelaw, and was held to be the amount of land that a team of two oxen could plow in a single annual season. It was equivalent to a quarter of a hide, so was nominally thirty acres.[1] A ‘virgater’ would thus be a peasant who occupied or worked this area of land, and a ‘half virgater’ would be a person who occupied or worked about 15 acres (61,000 m2).

The Danelaw equivalent of a virgate was two oxgangs, or ‘bovates’: as these names imply, the oxgang or bovate was considered to represent the amount of land that could be worked in a single annual season by a single ox, and therefore equated to half a virgate. As such, the oxgang represented a parallel division of the carucate. Accordingly, a 'bovater' is the Danelaw equivalent of a half virgater.

‘Virgate’ is an anglicisation of the Medieval Latin virgata. In some parts of England, it was divided into four nooks (Middle English: noke; Medieval Latin: noca). Nooks were occasionally further divided into a farundel (Middle English: ferthendel; Old English: fēorþan dǣl, "fourth deal, fourth share")
