4.1 The use of the body measurement information in Tables 1-4 will assist manufacturers in developing patterns and garments that are consistent with the current anthropometric characteristics of the population of interest. This practice should, in turn, reduce or minimize consumer confusion and dissatisfaction related to apparel sizing. (Also refer to ISO 3635 Size Designation Procedures.)

4.2 Three-dimensional avatars depicting each of the children’s sizes were created by Alvanon, Inc. and included in this standard to assist manufactures in visualizing the posture, shape, and proportions generated by the measurement charts in the accompanying tables. (See Figs. 1-9.)

FIG. 1 Form Front 2–6

FIG. 2 Form Side 2–6

FIG. 3 Form Back 2–6

FIG. 4 Form Front 7–20 Reg. Boys

FIG. 5 Form Side 7–20 Reg. Boys

FIG. 6 Form Back 7–20 Reg. Boys

FIG. 7 Form Front 4–20 Slim Boys

FIG. 8 Form Side 4–20 Slim Boys

FIG. 9 Form Back 4–20 Slim Boys

1.1 These tables list body measurements of boys sizes. Although these are body measurements, they can be used as a baseline in designing apparel for boys in this size range when considering such factors as fabric type, ease for body movement, styling, and fit.

1.2 The maximum age for the Boy’s chart is 15 years old to the size 20.

1.3 The size table includes the range of toddler sizes; these values are for both girls and boys and will be included in the girl’s standard as well.

1.4 These tables list body measurements for the complete range of Boys sizing. (Regular, Slim) Slim subjects are of same stature (height), with a slimmer body, and lower body weight than regular subjects as illustrated by the measurement charts.

1.5 The values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
