The design guidelines for maps on screens constrain the symbol sizes due to the screen resolution limitations. However, high-resolution screens become increasingly popular and rethinking the map design for screens may be necessary. To investigate, if indeed currently available high-resolution screens create new rendering opportunities, first the related scientific work was reviewed on related topics such as visual acuity, visual display resolution, visual variables, and design guidelines for screens. Furthermore, the study with 27 participants was conducted, focusing on shape difference legibility for point and line symbols. The experiment was designed establish the smallest legible point symbols on tested high-resolution screens, and to inquire whether the screen resolution indeed limits the smallest symbols legibility. The results suggest, that only few people with perfect vision are likely to benefit from high-resolution displays. The minimal sizes of circles, squares and triangles were established for tested screen resolutions and compared to legibility results for proposed line symbols. Lastly, study limitations and research outlook was discussed.
