Etymology: Middle English, from Old English higid, hid
1) A unit of measurement for assessment of tax, theoretically 120 acres, although it may vary between 60 and 240 acres. It is by custom the land that can be cultivated by one eight ox plow in one year.
(MEDIEV-L. Medieval Terms)
2) Originally the land necessary to sustain a peasant household. Sometimes reckoned at 120 acres but in fact the hide varied according to locality, date, and government needs.
(Wood, Michael. Domesday: A Search for the Roots of England, 214)
3) An Anglo-Saxon term still used in many parts of the country, and commonly at this period as a measurement of land, roughly equivalent to the carucate, but more properly a unit of assessment, e.g., to taxation.
(Warren, W.L. Henry II, 635)
