EN 13402


EN 13402 Size designation of clothes is a European standard for labelling clothes sizes. It is based on body dimensions, measured in centimetres. It replaces many older national dress-size systems in popular use before the year 2007. Acceptance of this form of standardisation varies from country to country. For example, the Spanish Ministry of Health and Consumer Affairs has commissioned a study to categorise female body types with a view to harmonising Spanish clothing sizes with EN-13402. Few other countries are known to have followed suit. For children's clothing it is the de facto standard in most of Europe already.

Background

There are three approaches for size-labelling of clothes:
; Body dimensions: The label states the range of body measurements for which the product was designed.
; Product dimensions: The label states characteristic dimensions of the product.
; Ad hoc size: The label states a size number or code with no obvious relationship to any measurement.
Traditionally, clothes have been labelled using many different ad hoc size systems.
This approach has led to a number of problems:
Therefore, the European standards committee CEN/TC 248/WG 10 started in 1996 the process of designing a new modern system of labelling clothes sizes, resulting in the standard EN 13402 "Size designation of clothes".
It is based on:
The first part of the standard defines the list of body dimensions to be used for designating clothes sizes, together with an anatomical explanation and measurement guidelines. All body dimensions are measured, preferably without or as few as possible clothes, in centimetres, except for the body mass.
The standard also defines a pictogram that can be used in language-neutral labels to indicate one or several of the following body dimensions.
; 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 Adam's 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, under the armpits, and across the chest
; bust girth : maximum horizontal girth measured during normal breathing with the subject standing erect and the tape-measure passed horizontally, under the armpits, and across the bust prominence
; underbust girth : horizontal girth of the body measured just below the breasts
; waist girth : girth of the natural waistline between the top of the hip bones and the lower ribs, measured with the subject breathing normally and standing erect with the abdomen relaxed
; hip girth : horizontal girth measured round the buttocks at the level of maximum circumference
; height : vertical distance between the crown of the head and the soles of the feet, measured with the subject standing erect without shoes and with the feet together
; 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, over the elbow, to the far end of the prominent wrist bone, with the subject's right fist clenched and placed on the hip, and with the arm bent at 90°
; hand girth: maximum girth measured over the knuckles 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 13402-2: Primary and secondary dimensions

The second part of the standard defines for each type of garment one "primary dimension".
This is the body measure according to which the product must be labelled.
Where men's garments use the chest girth, women's clothes are designed for a certain bust girth.
For some types of garment, a single measure may not be sufficient to select the right product. In these cases, one or two "secondary dimensions" can be added to the label.
The following table shows the primary and secondary dimensions listed in the standard, leaving out the redundant words girth, length and size for better overview.

EN 13402–3: Measurements and intervals

The third part of the standard defines preferred numbers of primary and secondary body dimensions.
The product should not be labelled with the average body dimension for which the garment was designed. Instead, the label should show the range of body dimensions from half the step size below to half the step size above the design size.
For heights, for example, the standard recommends generally to use the following design dimensions, with a step size of 8 cm:
Height...160168176184192200...
Range...156–164164–172172–180180–188188–196196–204...

For trousers, the recommended step size for height is 4 cm:
Height...156160164168172176180184188192196200...
Range...154–158158–162162–166166–170170–174174–178178–182182–186186–190190–194194–198198–202...

The standard defines similar tables for other dimensions and garments, only some of which are shown here.

Men

The standard sizes and ranges for chest and waist girth are defined in steps of 4 cm:
Chest girth84889296100104108112116120126132138144

Example: While manufacturers will typically design clothes for chest girth = 100 cm such that it fits waist girth = 88 cm, they may also want to combine that chest girth with neighbouring waist girth step sizes 84 cm or 92 cm, to cover these drop types as well.
The standard also suggests that neck girth can be associated with chest girth:

Women

Dress sizes

The standard sizes and ranges for bust, waist and hip girth are mostly based on a step of 4 cm, for larger sizes 5 cm or 6 cm :

Bra sizes

The European standard EN 13402 also defines bra sizes based on the "bust girth" and the "underbust girth". Bras are labeled with the under bust girth, followed by a letter code that indicates the "cup size" defined below, according to this table defined by the standard.
The standard sizes for brassiere are based on a step of 5 cm:
Underbust girth6065707580859095100105110115120125
Range58–6263–6768–7273–7778–8283–8788–9293–9798–102103–107108–112113–117118–122123–127

The secondary dimension cup size can be expressed in terms of the difference
and can be labelled compactly using a letter code appended to the underbust girth:
CodeAAABCDEFGH
Cup size range10–1212–1414–1616–1818–2020–2222–2424–2626–28

;Example 1: Bra size 70B is suitable for women with underbust girth 68–72 cm and bust girth from 82–84 cm to 86–88 cm.
;Example 2: A woman with an underbust girth of 89 cm and a bust girth of 108 cm has cup size 19 cm or "D". Her underbust girth rounded to the nearest multiple of 5 cm is 90 cm. Therefore, her bra size according to the standard is 90D.

Letter codes

For clothes where a larger step size is sufficient, the standard also defines a letter code. This code represents the bust girth for women and the chest girth for men. The standard does not define such a code for children.
Each range combines two adjacent size steps. The ranges could be extended below XXS or above 3XL if necessary.

EN 13402-4: Coding system

The fourth part of the standard is still under review. It will define a compact coding system for clothes sizes. This was originally intended primarily for industry use in databases and as a part of stock-keeping identifiers and catalogue ordering numbers, but later users have also expressed a desire to use compact codes for customer communication. Writing out all the centimetre figures of all the primary and secondary measures from EN 13402-2 can – in some cases – require up to 12 digits. The full list of centimetre figures on the pictogram contains a lot of redundancy and the same information can be squeezed into fewer characters with lookup tables. EN 13402-4 will define such tables.
An earlier draft of this part of the standard attempted to list all in-use combinations of EN 13402-3 measures and assigned a short 2- or 3-digit code to each. Some of the industry representatives involved in the standardization process considered this approach too restrictive. Others argued that the primary dimension in centimetres should be a prominent part of the code. Therefore, this proposal, originally expected to be adopted in 2005, was rejected.

Since then, several new proposals have been presented to the CEN working group. One of these, tabled by the , proposes a 5-character alphanumeric code, consisting of the 3-digit centimetre figure of the primary body dimension, followed by one or two letters that code a secondary dimension, somewhat like the system already defined for bra sizes. For example, an item designed for 100 cm bust girth, 104 cm hip girth and 176 cm height could bear the compact size code "100BG". This proposal was agreed upon in 2006, but later disregarded. A paper by Bogusławska-Bączek published in 2010 showed that there were still significant difficulties in identifying clothing sizes.
