EN 13402
EN 13402 is a European standard for labeling clothes
sizes. It is based on body dimensions, measured in
centimetres. It aims to replace many older national dress-size
systems, starting in the year 2006.
There are three approaches for size-labeling of
clothes:
- body dimensions: The product label states for
which range of body dimensions the product was designed.
(Example: bike helmet labeled "head girth: 56–60 cm", shoe
labeled "foot length: 28 cm")
- product dimensions: The label states
characteristic measures of the product. (Example: jeans
labeled with their inner-leg length in centimeters or
inches, i.e. not the – several centimeters longer – inner
leg length of the intended wearer)
- ad-hoc size: The label provides a size number or
code with no obvious relationship to any measurement.
(Example: Size 12, XL)
Traditionally, clothes have been labeled using many
different ad-hoc size systems. This approach has led to a
number of problems:
- Country-specific or even vendor-specific labels create
additional costs.
- Ad-hoc sizes have changed with time, often due to
"vanity labeling", an inflation in body dimensions
associated with a size, to avoid confronting aging customers
with uncomfortable anthropometric truths.
- Mail-order purchasing requires accurate methods for
predicting the best-fitting size.
- Many garments need to be selected based on two or three
body dimensions to fit adequately, and not a single scalar.
- Scalar ad-hoc sizes based on 1950s anthropometric
studies are no longer adequate, as changes in nutrition and
life styles have shifted the distribution of body
dimensions.
Therefore, the European standards body CEN started in 1996
the process of designing a new modern system of labeling
clothes sizes, resulting in the standard EN 13402 "Size
designation of clothes".
It is based on
- body-dimensions
- the metric system
- data from new anthropometric studies of the European
population performed in the late 1990s
- similar existing international standards (ISO 3635,
etc.)
EN 13402-1: Terms, definitions and body measurement
procedure
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:
- 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 (scapulae),
under the armpits (axillae), 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
(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
- 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
- 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 (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
These dimensions are meant to be measured preferably
without or as few as possible clothes.
All body dimensions are measured in centimeters, 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
above body dimensions.
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.
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. Secondary dimensions are
shown in parenthesis.

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 labeled with the average body
dimension for which the garment was designed (i.e., not
"height: 176"). 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").
For heights, for example, the standard recommends generally
to use the following design dimensions, with a step size of 8
cm:
Height |
... |
160 |
168 |
176 |
184 |
192 |
200 |
... |
Range |

164-172 |
172-180 |
180-188 |
188-196 |
196-204 |
... |
For trousers, the recommended step size for height is 4
cm:

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

The above table is for drop = -12 cm, where
- drop = waist girth - chest 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 neighboring 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 according to this table:

The secondary dimension bust size can be expressed
in terms of the difference
- cup size = bust girth - underbust

to the underbust girth:

Example: Bra size 70B is suitable for women with
underbust girth 68-72 cm and bust girth 84-86
cm.
Letter codes
For clothes were 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.

EN 13402-4: Coding system
The fourth part of the standard is still under review and
is expected to be published in early 2006. It describes a
compact coding system for clothes sizes. It is mostly intended
for industry to use in databases and as a part of
stock-keeping identifiers and catalogue ordering numbers.
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 centimeter figures on the
pictogram contains a lot of redundancy and the same
information can be squeezed into fewer digits with lookup
tables. EN 13402-4 defines several such tables. They list all
in-use combinations of EN 13402-3 measures and assign a short
2- or 3-digit code to each.
