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[1] 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.


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. (For example: bike helmet label stating "head girth: 56–60 cm")
Product dimensions
The label states characteristic dimensions of the product. (For example: jeans label stating inner leg length of the jeans in centimetres or inches (not inner leg measurement of the intended wearer))
Ad hoc size
The label states a size number or code with no obvious relationship to any measurement. (For example: Size 12, XL)

Traditionally, clothes have been labelled using many different ad hoc size systems. This approach has led to a number of problems:

  • For many types of garments, size cannot be adequately described by a single number because a good fit requires a match between two (or sometimes three) independent body dimensions. This is a common issue in sizing jeans.
  • Ad hoc sizes have changed with time due to changing demographics and increasing rates of obesity. This is often portrayed in media as vanity sizing.
  • Scalar ad hoc sizes based on 1950s anthropometric studies are no longer adequate, as changes in nutrition and life style have shifted the distribution of body dimensions.
  • Mail order requires accurate methods for predicting the best-fitting size.
  • Country-specific and vendor-specific labels incur additional costs.

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:

EN 13402-1: Terms, definitions and body measurement procedure

The first part[2] 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 (circumference) 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 (♂ men)
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
bust girth (♀ women)
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 (preferably measured with moderate tension over a brassiere that shall not deform the breast in an unnatural way and shall not displace its volume)
underbust girth (♀ women)
horizontal girth of the body measured just below the breasts
waist 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 relaxed
hip girth (♀ women)
horizontal girth measured round the buttocks at the level of maximum circumference
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 (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)
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 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 (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 13402-2: Primary and secondary dimensions

The second part[3] 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 (in bold) 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[4] 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 (i.e., not "height: 176 cm."). 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 (e.g., "height: 172–180 cm.").

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 156160164168172176 180184188192196200
Range 154–158158–162162–166166–170170–174174–178 178–182182–186186–190190–194194–198198–202

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


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

Men’s standard sizes for drop = −12 cm
Chest girth 84889296100104108112 116120126132138144
Range 82–8686–9090–9494–9898–102102–106106–110110–114 114–118118–123123–129129–135135–141141–147

drop = waist girthchest girth.

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 (−16 cm and −8 cm) as well.

The standard also suggests that neck girth can be associated with chest girth:

Association of neck and chest girth
Neck girth 3738394041424344 4546.54849.551
Range 36.5–37.537.5–38.538.5–39.539.5–40.540.5–41.541.5–42.542.5–43.543.5–44.5 44.5–45.845.8–47.347.3–48.848.8–50.350.3–51.1
Chest girth 889296100104108112116 120126132138144

The standard further suggests that arm length can be associated with height:

Association of arm length and body height
Height 156160164168172176180184188192196200
Arm length 606162636465666768697071
Range 59–6060–6161–6262–6363–6464–6565–6666–6767–6868–6969–7070–71


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 (hip) or 6 cm (bust and waist):

Women’s standard sizes for drop = 16 cm
Bust girth 768084889296100104110 116122128134140146152
Range 74–7878–8282–8686–9090–9494–9898–102102–107107–113 113–119119–125125–131131–137137–143143–149149–155

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 (rounded to the nearest multiple of 5 cm), 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 girth 6065707580859095 100105110115120125
Range 58–6263–6768–7273–7778–8283–8788–9293–97 98–102103–107108–112113–117118–122123–127

The secondary dimension cup size can be expressed in terms of the difference

cup size = bust girthunderbust girth

and can be labelled compactly using a letter code appended to the underbust girth:

Cup size range 10–1212–1414–1616–1818–2020–2222–2424–2626–28
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 (= 108 cm – 89 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.

Meaning Code Chest girth (men) Bust girth (women)
extra extra smallXXS 70–7866–74
extra smallXS 78–8674–82
smallS 86–9482–90

extra extra extra large3XL 129–141131–143
4XL 141–154143–155
5XL 154–166155–167

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 European Association of National Organisations of Textile Traders (AEDT), 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.[5] 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.[6] A paper by Bogusławska-Bączek published in 2010 showed that there were still significant difficulties in identifying clothing sizes.[7]
