What is "modulor"

The Modulor is an anthropometric scale of proportions devised by the Swiss-born French architect Le Corbusier (1887–1965).

It was developed as a visual bridge between two incompatible scales, the imperial and the metric system. It is based on the height of a man with his arm raised.

It was used as a system to set out a number of Le Corbusier's buildings and was later codified into two books.
