The European Clothing StandardEN 13402EN 13402 is a European standard for labelling clothes sizes. It is based on bodydimensions, measured in centimetres. It aims to replace many older nationaldress-size systems, starting in the year 2006.There are three approaches for size-labelling of clothes: Body dimensions: The product label states for which range of bodydimensions the product was designed. (Example: bike helmet labeled "headgirth: 56–60 cm", shoe labeled "foot length: 28 cm") Product dimensions: The label states characteristic measures of theproduct. (Example: jeans labeled with their inner-leg length in centimeters orinches, i.e. not the – several centimeters longer – inner leg length of theintended wearer) Ad-hoc size: The label provides a size number or code with no obviousrelationship to any measurement. (Example: Size 12, XL)
EN 13402-1: Terms, definitions and body measurementprocedureThe first part of the standard defines the list of body dimensions tobe used for designating clothes sizes, together with an anatomicalexplanation and measurement guidelines:-Head girth: maximum horizontal girth of the head measured above the ears.-Neck girth: girth of the neck measured with the tape measure passed 2 cm below the Adams apple and at the level of the 7th cervical vertebra.-Chest girth: maximum horizontal girth measured during normal breathing with the subject standing erect and the tape-measure passed over the shoulder blades (scapulae), under the armpits (axillae), and across the chest.
Continued…Bust girth Maximum horizontal girth measured during normal breathing with the subject standing erect and the tape-measure passed horizontally, under the armpits (axillae), and across the bust prominence (over a brassiere that shall not deform the breast in an unnatural way and shall not displace its volume)Underbust girth Horizontal girth of the body measured just below the breastsWaist girth Girth of the natural waistline between the top of the hip bones (iliac crests) and the lower ribs, measured with the subject breathing normally and standing erect with the abdomen relaxedHip girth Horizontal girth measured round the buttocks at the level of maximum circumferenceHeight Vertical distance between the crown of the head and the soles of the feet, 4 measured with the subject standing erect without shoes and with the feet together (for infants not yet able to stand upright: length of the body measured in a straight line from the crown of the head to the soles of the feet)
Continued…Inside leg length Distance between the crotch and the soles of the feet, measured in a straight vertical line with the subject erect, feet slightly apart, and the weight of the body equally distributed on both legs.Arm length Distance, measured using the tape-measure, from the armscye/shoulder line intersection (acromion), over the elbow, to the far end of the prominent wrist bone (ulna), with the subjects right fist clenched and placed on the hip, and with the arm bent at 90°.Hand girth Maximum girth measured over the knuckles (metacarpals) of the open right hand, fingers together and thumb excluded.Foot length Horizontal distance between perpendiculars in contact with the end of the most prominent toe and the most prominent part of the heel, measured with the subject standing barefoot and the weight of the body equally distributed on both feet.Body mass Measured with a suitable balance in kilograms.
EN 13402-3: Measurements and intervalsThe third part of the standard defines preferred numbers ofprimary and secondary body dimensions.The product should not be labeled with the average bodydimension for which the garment was designed (i.e., not "height:176"). Instead, the label should show the range of bodydimensions from half the step size below to half the step sizeabove the design size (e.g., "height: 172-180").For heights, for example, the standard recommends generally touse the following design dimensions, with a step size of 8 cm:
For trousers, the recommended step size for height is 4 cm:The standard defines similar tables for other dimensions andgarments, only some of which are shown here.
MenThe standard sizes and ranges for chest and waist girthare:
The above table is for drop = -12 cm, wheredrop = waist girth - chest girth.Example: While manufacturers will typically design clothes forchest girth = 100 cm such that it fits waist girth = 88 cm, theymay also want to combine that chest girth with neighboringwaist girth step sizes 84 cm or 92 cm, to cover these drop types(-16 cm and -8 cm) as well.The standard also suggests that neck girth can be associatedwith chest girth according to this table:
WomenDress sizesThe standard sizes and ranges for bust, waist and hip girth are:
Bra sizesThe standard sizes for brassiere are:
The secondary dimension bust size can be expressed in terms ofthe differencecup size = bust girth - underbust girthand can be labeled compactly using a letter code appended tothe Underbust girth:Example: Bra size 70B is suitable for women with underbustgirth 68-72 cm and bust girth 84-86 cm.
Letter codesFor clothes were a larger step size is sufficient, the standard alsodefines a letter code. This code represents the bust girth forwomen and the chest girth for men. The standard does notdefine such a code for children.
EN 13402-4: Coding systemThe fourth part of the standard is still under review and isexpected to be published in early 2006. It describes a compactcoding system for clothes sizes. It is mostly intended forindustry to use in databases and as a part of stock-keepingidentifiers and catalogue ordering numbers. Writing out all thecentimetre figures of all the primary and secondary measuresfrom EN 13402-2 can in some cases require up to 12 digits. Thefull list of centimeter figures on the pictogram contains a lot ofredundancy and the same information can be squeezed intofewer digits with lookup tables. EN 13402-4 defines several suchtables. They list all in-use combinations of EN 13402-3 measuresand assign a short 2- or 3-digit code to each.
