London Guildhall Photo, Standards of length

License this photo for your own use

Set into a window embrasure on the south wall of the great hall are a set of standard measures of length made from brass. These standards were the official measures of length against which any merchandise sold in the city could be measured. There are three standard lengths here; one foot, two feet, and a yard. Bras rods measuring 100 feet and 66 feet are set into the floor of the hall.
