Label size design : aesthetics and effeciency

Considering label as one of the important map component, this paper is an attempt to provide empirical evidence of label size design rules and frames which is based on the design aesthetics and efficiency. Determining the ‘best’ legible label size is critical concern involves testing design aspect and needs. Both aesthetics and efficiency can set the design frames for better perception and legibility. Aesthetics was calculated by determining users´ preference of different use of label sizes, whereas efficiency was calculated by measuring time to locate targets of different. Both areal and point data were involved in the study to determine the combination of the two measurements of label size design. Digital maps were designed and presented to users as they were firstly asked about their preference of different use of label size, and secondly they were asked to locate different label size. The intersection between the first test and the second one attributes the frames for label size design. The correlation between the preferable sizes and the efficient sizes is being traced and the relation between label size aesthetics and efficiency is being identified. This study indicates the need to test other visual variable in order to serve many labelling functions
