Ergonomics is a scientific discipline aimed at optimizing the interaction between human beings and their work environment, promoting well-being and operational performance. In this context, the present study aims to design an ergonomic work surface based on anthropometric data and postural task evaluation. The research was conducted under a quantitative approach, applied type, and descriptive scope. Sixteen anthropometric measurements in a seated position were obtained from a sample of 20 individuals using calibrated instruments and standardized procedures. The data were statistically processed through descriptive measures and the calculation of the 5th and 95th percentiles in order to establish inclusive dimensional parameters. Additionally, the RULA method was applied to assess the level of postural risk associated with the analyzed activity. The results showed that the functional zone delimitation based on percentiles covered approximately 90% of the evaluated population. The RULA assessment revealed a moderate risk level (score 4), indicating the need for adjustments in workstation design. An adjustable surface in height and inclination was proposed as a corrective measure to improve body alignment and reduce biomechanical load. The study demonstrates that integrating anthropometric analysis and postural evaluation allows the development of technically grounded ergonomic design proposals.
