Because of facing the numerous garments fit problems to ready-to-wear industry, in recent years there has been a remarkable increase in anthropometric surveys taking place worldwide for development of sizing systems. It has been acknowledged that the extent to which one sizing system may be applied to different populations is limited due to the variability of body shapes and sizes. Various countries have developed their own sizing systems in order to reduce problems associated with clothing sizes and fit. So the purpose of this paper is to present a detailed procedure used for the development of a size chart based on anthropometric body measurements of Woldia town tailors’ men customers. A total of 1384 men customers aged 18 and above years were measured using manual measuring procedures. A quantitative approach was used to generate descriptive statistics from the raw data to obtain five sizes of a body measurement table. A step by step procedure used for analyzing the raw data obtained from the anthropometric body survey is presented. Size codes, size limits and verifiable size charts are generated. This study contributes greatly to knowledge of size chart by providing a detailed procedure involved in developing research based anthropometric data and will serve as the basis for other future research in Woldia town as well as in Ethiopia. Further anthropometric studies should be conducted to cover all age categories of women and men in Woldia and Ethiopia as a whole.
