"The subject of human scale, while historically given importance in designliterature, has never been well understood or integrated into design praxis.A complex and definitionally varied conceptualization, the term is appliedequally to aspects of human dimensions and social actions alike. A review ofpublished design drawings in the United States during this century reveals anumber of conceptual shifts in the meaning associated with human scale thatparallel the introduction of changing design paradigms. Less clear, and thesubject of this paper, is the identification of the spatial attributes that havebeen historically associated with human scale.Most commonly used to describe the relative size of elements in the urbanlandscape, human scale is still one of the most important visual relation-ships associated with the design of urban space. Nonetheless, the term car-ries a range of meanings, which include: the size of objects or spatial ele-ments relative to the dimensions and proportions of the human body; thesense that places belong to people and that the objects of place are personoriented; and, denotes a function of "meeting" within topological urban spac-es - those that are clearly enclosed. In the twentieth century, the use of theterm in urban design clearly moved from a concern with the size and pro-portions of topologically defined urban plazas, described by architecturalelements lacking in the same, to that created by the "International Style",which initially focused human scale applications on urban architecturalelements, while ignoring the same in the design of urban spaces. And as anemphasis for human scale and enclosure returned to the design of urban openspace, it reciprically became less of an issue in the design of urban build-ings. Currently, a phenomenological perspective suggests that the urbanlandscape can be understood on at least four separate levels of scale - that ofthe entire city, that of the street or square, that of individual buildings or structures, and that of specific architectural elements - with the eye mov-ing among these various levels as it searches for meaning.A descriptive study of human scale was conducted to identify the significantattributes associated with human scale at these various levels. The study in-volved a review of drawings and photographs that appeared in popular designpublications in the United States during this century, since it was reasonedthat these sources represented normative spatial concepts of human scalefor a given period. A list of attributes were developed based on the frequencyof their occurance in the publications and a histogram produced based on thefrequency of their distribution throughout the century. This paper describesthe results of that study and discusses the implications of human scale at-tributes and their usage in the design and communications of urban space inthe future."
