Lack of anthropometric data has been reported to be primarily responsible for furniture mismatch, which has resulted in the high prevalence of musculoskeletal disorders among schoolchildren. This study is aimed at determining appropriate anthropometry dimensions that can be used in school furniture manufacturing for Tanzania’s children. Anthropometric data from 12 body regions; which includes stature height, body weight, shoulder breadth, popliteal height, reaching (overhead) height, eye height, elbow height, hip breadth, arm length, thigh thickness, buttock-popliteal length and buttock-knee length; were collected from 468 children, comprising 236 boys and 232 girls. Percentile distributions of these dimensions, grouped into four age groups, 6-to 8-, 9-to 11-, 12-to 14-and 15-to 17-year-olds were presented. However, there was no significant difference in these dimensions between boys and girls, except among the 9-11-year-olds. The results from this study will provide design inputs to help furniture manufacturers to provide well fitted furniture for Tanzania’s schoolchildren because it is suitable for both genders and for children from both rural and urban centres.
