Ready-made garments are popular because of readily availability in the retail shops. Ready-made garments production requires standard measurement for each age group which depends on anthropometry. Measurement of ready-made garments varies on the anthropometry of a nation. The goal of the study was to develop a measurement chart and identify the size ratio and color preferences of both male and female young adults of Bangladeshi origin which is not in literature. A different point of measurement along with their heights of 409 males’ and 356 females’ young adult for the Tshirt was taken. Based on height, the male and female young adults were categorized into five sizes (S, M, L, XL, and XXL). It is found that the size ratio was around S: M: L: XL: XXL = 6: 32: 37: 18: 7 and 17: 30: 34: 13: 6 for male and female respectively. Proposed standard measurement of Length from highest point of shoulder, Centre front length, Armhole, Sleeve length, Neck width, Across shoulder, Half chest and Hem Width for size L for male is 68 cm, 63 cm, 23 cm, 19.5 cm, 21 cm, 44 cm, 49 cm and 49 cm for respectively. Preferences of color are quite wide of both male and female, most preferred color is blue among the male and black among the female. Two-third female adults preferred short sleeve t-shirt. Brands that are targeting to retail their Tshirt in the market of Bangladesh can use developed measurement sheets for the bulk production of T-shirt.
