National Standard
China's first national standard for the "Clothing Size Series" was born in 1981, officially approved and implemented by the National Technical Supervision Bureau. To develop China's first "Clothing Size Series" standard, the Ministry of Light Industry organized clothing professionals nationwide in 1974 to conduct a body shape survey of 400,000 people across 21 provinces and cities. The subjects included farmers, workers from light and heavy industries, commercial, government, arts, health, street residents, colleges, primary and secondary school students, kindergartens, and nurseries. The age distribution was: 1-7 years old children accounted for 10%, 8-12 years old children 15%, 13-17 years old teenagers 15%, and adults 60%. The survey measured 17 body parts, with measurement data based on the net body height and circumference. The data collected was summarized by the Institute of Mathematics of the Chinese Academy of Sciences. From the 17 body parts, 12 were selected for men: upper body length, arm length, chest circumference, neck circumference, total shoulder width, back width, front chest width, overall height, height, lower body length, waist circumference; for women, waist height and back waist height were added, totaling 14 body parts. These data were organized and calculated to find the average, standard deviation, and related data for each part, establishing clothing size standards suitable for the Chinese body shape.
The first "Clothing Size Series" standard, after 10 years of promotion and application, added more body shape data and was approved and released in 1991, with the standard code: GB1335.1—1335.91 "Clothing Size Series" national standard.
After 7 years of use, the "Clothing Size Series" released in 1991 was revised, abolishing the 5.3 series and adding infant sizes. These are GB/T1335.1—97 Clothing Size (Men), GB/T1335.2—97 Clothing Size (Women), and GB/T1335.3—97 Clothing Size (Children) three clothing size standards. The current "Clothing Size Series" was revised and improved again in 2008, which are the GB/T1335.1-2008 Clothing Size (Men) and GB/T1335.2-2008 Clothing Size (Women) we use today.
1. Size Definition
"Size" refers to the person's height, expressed in centimeters (cm), and is the basis for designing and selecting clothing length.
"Shape" refers to the person's chest or waist circumference, expressed in centimeters (cm), and is the basis for designing and selecting clothing circumference.
It should be noted: the size and shape refer to the person's net body measurements, not the specific clothing specifications. Clothing specifications must be based on the person's net body measurements, with appropriate allowances added for different parts.
2. Body Shape Classification
Since the shape circumference includes two data points: chest and waist circumference, body shapes with the same chest circumference may have different waist circumferences, resulting in different body shapes. To make "size" correctly reflect body shape, the 1991 "Clothing Size Series" standard added four body shape marks: Y, A, B, and C.
The basis for dividing body shape marks is calculated from the difference between chest and waist circumference. The classification codes and ranges are shown in the table above. Types A and B are more common in the population, accounting for about 70%; Y type accounts for about 20%; C type is less common, below 10%.
3. Size Mark
Clothing products must have size marks, which are expressed by writing the size value first, followed by the shape value, separated by a slash. The shape is followed by the body shape classification mark. Examples are as follows:
Correct marks: 170/88A 170/84B 160/63Y
Incorrect marks: 170-88A 170×88A A170/88
To consider consumer habits and facilitate selection, clothing products at this stage may also include specifications or codes such as S, M, L in addition to the size marks, but the size mark must be present.
4. Size Series
The size and shape of the body are arranged in a regular graded order, which is called the size series. The size grading is 5cm (for children under 130cm, grading is 10cm), and the shape grading is 4cm or 2cm.
Combining the size grading and shape grading, there are two types: 5.4 series and 5.2 series. The notation is the size grading number first, followed by the shape grading number, separated by a dot. It should not be written as 5-4 series or 5/4 series.
It should be noted: the size grading refers to the person's height grading, not the grading of clothing length or pants length. Taking the 5.4 series as an example, it means the size grading is 5cm, and the shape grading is 4cm, that is:
Size (person's height): 160, 165, 170, 175, ...
Shape (person's circumference): 80, 84, 88, 92, ...
5. Intermediate Body
Based on a large amount of measured body data, the average value calculated is the intermediate body (no intermediate body is set for children). It reflects the average level of height, chest circumference, waist circumference, and other parts of various body shapes of Chinese adult men and women, and has certain representativeness. However, the intermediate body is not fixed. According to the 1974 national survey, the intermediate body at that time was: men's average height 165cm, chest circumference 88cm, waist circumference 76cm; women's average height 155cm, chest circumference 84cm, waist circumference 72cm. Ten years later, a re-survey found that the men's intermediate height increased by 5cm to 170cm, and the women's overall height also increased. Other data changed little.
The purpose of understanding the intermediate body is to accurately design well-fitting clothing specifications. Design specifications must center on the intermediate body and extend up, down, left, and right by certain grading values to form a size series.
6. Size Application
The data marked by the size sometimes matches the body specifications exactly, sometimes approximately. Therefore, when matching sizes, the nearest approximation method can be referred to. Examples are as follows:
Size: 165 Height: 162.5 163 167 167.5
170 167.5 168 172 172.5
175 172.5 173 177 177.5 (cm)
Type: 84 Bust: 82 83 85 86
88 86 87 89 90
92 90 91 93 94 (cm)
When selecting clothing, it is not necessary to rigidly follow the size type; choices can be made within a certain range based on clothing style, color, body shape, and personal preference.
7. Control Points
The values of control points are one of the main components of the "standard"; together with the "size series," they form a whole and serve as the basis for designing clothing specifications. Control points for length include height, cervical vertebra height, full arm length, and waist height. Control points for circumference include bust, waist, neck, arm, and total shoulder width.
The clothing specifications such as garment length, sleeve length, bust, neck circumference, total shoulder width, pants length, waist, and hip circumference are determined by adding different ease allowances to the values of control points. For convenience, garment length, sleeve length, and pants length specifications are generally determined by adding or subtracting ease allowances based on the percentage of the medium size in the "size" series. Bust and waist specifications are determined by the "type" plus ease allowances. Neck circumference, total shoulder width, and hip circumference values plus ease allowances form the clothing circumference specifications.
