Introduction
Anthropometric data used for technological design have been included in many ISO product standards.
However, different review cycles make it impossible for simultaneous revision of these product standards
as new anthropometric data become available. This document is intended to serve as a continually
updated repository of the most current national anthropometric data. It is intended to make current and
updated anthropometric data available for inclusion by reference in the various ISO product standards
requiring ISO 7250-1 body measurement input, wherever national specificity of design parameters is
required.
Body dimensions of people have been increasing in many countries over the last severalpast few decades.
The rate of increase differs from country to country. In the area where significant secular change is going
on, statistical summaries described in this document will be outdated sooner. Therefore, it is intended
that statistical summaries of human body measurements described in this document be updated as new
data become available.
This document provides body dimensions data for people of working age. In order to provide practical
data, the working age population is not defined and the decision is left to each country, because working
age differs amongbetween countries. However, the data for children under 16 years are not included.
To ensure the comparability of measurements, body dimensions in this document are measured
according to ISO 7250-1:2017. To ensure the reliability of statistical data, databases from which statistics
1
are calculated adhere to ISO 15535:2012 and ISO/FDIS 15535:2022.:—.
Users of this document and ISO member bodies are encouraged to submit anthropometric data for this
document. Users with knowledge of additional anthropometric data are encouraged to contact their ISO
member body, and copy the ISO/TC 159/SC 3 committee manager on the communication (e-mail
addresses can be found on the ISO website: https://www.iso.org/). Member bodies should willcan
contact the ISO/TC 159/SC 3 committee manager directly.

TECHNICAL REPORT ISO/DTR 7250-2:2023(E)
Basic human body measurements for technological design —
Part 2:
Statistical summaries of body measurements from national
populations
1 Scope
This document provides statistical summaries of body measurements measured according to ISO 7250-
1:2017, together with database background information for working age people prepared according to
ISO 15535:2012 in the national populations of individual ISO member bodies. This document also
describes the process of the measurement and preparation of statistical summaries.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at https://www.electropedia.org/
3.1
Secularsecular change
Changeschanges in mean body dimensions of a specific group over time.
Note 1 to entry: The direction of change can be positive or negative.
4 Anthropometric measurements
Measuring conditions and definitions of measurements in this document are the same as those described
in ISO 7250-1:2017. Body measurements are described in millimetres (mm) or kilograms (kg).
Body measurements obtained from 3-D systems or obtained using instruments different from those
described in ISO 7250-1:2017 are confirmed by member bodies to be sufficiently close to those produced
by the traditional methods of ISO 7250-1:2017 according to ISO 20685-1:2018, Clause 5.
Sometimes a measurement is not performed exactly as described in ISO 7250-1:2017, but is very similar.
In such cases, the measurement can be substituted for the ISO 7250-1:2017 measurement if its value is
adequately close. To judge closeness, the method described in ISO 20685-1:2018 are is used. The criteria
for the judgment are given in Annex A.
The measured side (right or left) is described.

---------------------- Page: 10 ----------------------
ISO/DTR 7250-2:2023(E)
When measurements not described in ISO 7250-1:2017 are also available, the number of these
measurements and the reference are provided.
Age statistics are tabulated similarly and presented together with the anthropometric measurements.
5 Statistical procedures
5.1 Data editing
Before calculating statistical values, irregular values are detected and reviewed according to
2
ISO 15535:2012, Annex F or ISO/FDIS 15535:2022:—, Annex F.
5.2 Statistics
In this document, the following statistics are described for each measurement: sample size, mean,
standard deviation (SD),) and 1st, 5th, 50th, 95th and 99th percentile values.
5.3 Population stratification
Population can be stratified by gender, age, location, occupation or education. To keep this document at
a reasonable size, statistics are presented for females and males, but not for other strata.
5.4 Age stratification
In order to provide practical data and to keep this document at a reasonable size, only one age group,
including all working-age people, is considered.
5.5 Body measurements for representative body forms
Measurements for body forms representing large, medium and small types are useful for technological
design. While the medium type can be represented by P50 values for all measurements, fixed percentile
options are problematic for extreme body forms, such as those derived from all P5 or P95 values. When
sitting height and leg length are P5, height is smaller than P5. Though such a problem is well recognized,
there is no consensus on the method for obtaining measurements for body forms statistically
representing the variation in a population. Considering this lack of consensus, it was decided not to
present such data in this document.
6 Background information
6.1 General
Statistics of body dimensions are described together with the following information for users to judge
their reliability and context.
6.2 Background of database
6.2.1 Time period of examination
Year(s) of measurement.

ISO/DTR 7250-2:2023(E)
6.2.2 Location of examination
Name of the country and city.
6.2.3 Demographic data
For demographic data (e.g. gender, age, etc.),), information on the following items is provided:
a) definition of the working age;
b) description of participants;
c) number of participants by gender;
tend) 10-year age groups.
When more than one subgroup based on criteria other than the age and gender is involved, the
percentage of each subgroup is provided, if necessary.
6.2.4 Publication on the anthropometric research
The author, publication year, title of the publication and the name of publisher are provided when the
data have been published.
6.3 Representativeness of the sample
6.3.1 Sampling method
A description is given of the grounds on which the sample was judged to be representative of the intended
population. These include an examination of the sampling method and maycan also include the
comparison of height and weight in the measured sample data with those from a large sample
representing the intended population. If the data need to be weighted in order to be representative, then
the weighting method is described.
6.3.2 Information on secular change
When significant secular changes are going on, information on the rate of change over the last severalpast
few decades is presented, when available, and appropriate references are given.
6.4 Accuracy and reliability of measurements
6.4.1 Skill of measurers
The number of measurers and information on the skill of each measurer, such as intra-observer mean
absolute difference or technical error of measurement (TEM) or repeated measurements, are shown
when such data are available. When more than one measurer is involved, the methods used to control the
quality of the measurement technique are documented. When the research is continued for more than
one month, the method of quality control during the research period is documented.
6.4.2 Measurements from 3-D scanners
When measurements are extracted from 3-D scans, the results are compared to measurements obtained
by traditional methods using the procedures in ISO 20685-1:2018, Clause 5. Similarly, measurements
taken using instruments not described in ISO 7250-1 are compared to those obtained by traditional
methods.

7 Procedure for presenting member body statistics
7.1 General
This clause describes how the statistics given in this document are gathered and checked.
7.2 Submission of data
Users of this document and ISO member bodies are encouraged to submit anthropometric data for this
document. Users with knowledge of additional anthropometric data maycan contribute by contacting
their ISO member body and copying the ISO/TC 159/SC 3 secretariat on the communication (e-mail
addresses can be found on the ISO website: https://www.iso.org/). Member bodies willcan contact the
ISO/TC 159/SC 3 committee manager directly. When information is received, it will beis processed as
described belowin this clause.
7.3 One data set from each member body
In the case of countries with more than one possible database, the member body determines which of the
databases is to be used. If more than one set of statistics is submitted, the member body will be asked to
choose only one data set.
7.4 Meeting the criteria outlined in 5.2, 5.3 and 5.4
Member bodies will provide summary statistics that meet the criteria outlined in 5.2, 5.3 and 5.4. If the
criteria are not met on the first submission, the member body will be asked to resubmit the statistics
according to the criteria.
7.5 Examination of possible errors
7.5.1 General
Recognizing that errors can accidentally occur in any data set, the submitted summary statistics are
examined for reasonableness. The steps used are the following:those in 7.5.2 to 7.5.5.
7.5.2 Minima and maxima
The minima and maxima for each dimension are examined, comparing them to minima and maxima from
other member body submissions. If, minima or maxima are likely to be the result of errors, the member
body will be contacted to verify the submission.
7.5.3 Percentile values
The distance of the P1 and P99, P5 and P95 from the P50 percentile value are examined. If the distant
percentiles are unusually distant from the P50, the member body will be contacted to verify the
submission
7.5.4 Standard deviation (SD)
The standard deviation (SD) is compared to the standard deviationSD submitted by other member
bodies. If the standard deviationSD is unusually large or unusually small, the member body will be
contacted to verify the submission.
7.5.5 Comparison of mean or P50 values from member bodies
The mean or P50 values are examined with respect to mean or P50 values from other member bodies to
make sure that the dimension being reported is that described in ISO 7250-1:2017. If it appears that a
4 © ISO 2023 – All rights reserved
---------------------- Page: 13 ----------------------
ISO/DTR 7250-2:2023(E)
different measuring technique, or different measurement definition, has been used, the member body
will be contacted to verify the measurement procedure.
7.6 Marks on values likely to be in error
If resubmitted summary statistics are still likely to be in error, the published values are marked with a
footnote.
8 Statistics for ISO national members

Introduction
Anthropometric data used for technological design have been included in many ISO product standards.
However, different review cycles make it impossible for simultaneous revision of these product
standards as new anthropometric data become available. This document is intended to serve as a
continually updated repository of the most current national anthropometric data. It is intended to
make current and updated anthropometric data available for inclusion by reference in the various ISO
product standards requiring ISO 7250-1 body measurement input, wherever national specificity of
design parameters is required.
Body dimensions of people have been increasing in many countries over the past few decades. The rate
of increase differs from country to country. In the area where significant secular change is going on,
statistical summaries described in this document will be outdated sooner. Therefore, it is intended that
statistical summaries of human body measurements described in this document be updated as new
data become available.
This document provides body dimensions data for people of working age. In order to provide practical
data, the working age population is not defined and the decision is left to each country, because working
age differs between countries. However, the data for children under 16 years are not included.
To ensure the comparability of measurements, body dimensions in this document are measured
according to ISO 7250-1. To ensure the reliability of statistical data, databases from which statistics are
1)
calculated adhere to ISO 15535:2012 and ISO 15535:—.
Users of this document and ISO member bodies are encouraged to submit anthropometric data for this
document. Users with knowledge of additional anthropometric data are encouraged to contact their
ISO member body and copy the ISO/TC 159/SC 3 committee manager on the communication (e-mail
addresses can be found on the ISO website: https://www.iso.org/). Member bodies can contact the
ISO/TC 159/SC 3 committee manager directly.

populations
1 Scope
This document provides statistical summaries of body measurements measured according to
ISO 7250-1, together with database background information for working age people prepared according
to ISO 15535:2012 in the national populations of individual ISO member bodies. This document also
describes the process of the measurement and preparation of statistical summaries.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
secular change
changes in mean body dimensions of a specific group over time
Note 1 to entry: The direction of change can be positive or negative.
4 Anthropometric measurements
Measuring conditions and definitions of measurements in this document are the same as those
described in ISO 7250-1. Body measurements are described in millimetres (mm) or kilograms (kg).
Body measurements obtained from 3-D systems or obtained using instruments different from those
described in ISO 7250-1 are confirmed by member bodies to be sufficiently close to those produced by
the traditional methods of ISO 7250-1 according to ISO 20685-1:2018, Clause 5.
Sometimes a measurement is not performed exactly as described in ISO 7250-1, but is very similar.
In such cases, the measurement can be substituted for the ISO 7250-1 measurement if its value is
adequately close. To judge closeness, the method described in ISO 20685-1 is used. The criteria for the
judgment are given in Annex A.
The measured side (right or left) is described.
When measurements not described in ISO 7250-1 are also available, the number of these measurements
and the reference are provided.

Age statistics are tabulated similarly and presented together with the anthropometric measurements.
5 Statistical procedures
5.1 Data editing
Before calculating statistical values, irregular values are detected and reviewed according to
2)
ISO 15535:2012, Annex F or ISO 15535:—, Annex F.
5.2 Statistics
In this document, the following statistics are described for each measurement: sample size, mean,
standard deviation (SD) and 1st, 5th, 50th, 95th and 99th percentile values.
5.3 Population stratification
Population can be stratified by gender, age, location, occupation or education. To keep this document at
a reasonable size, statistics are presented for females and males, but not for other strata.
5.4 Age stratification
In order to provide practical data and to keep this document at a reasonable size, only one age group,
including all working-age people, is considered.
5.5 Body measurements for representative body forms
Measurements for body forms representing large, medium and small types are useful for technological
design. While the medium type can be represented by P50 values for all measurements, fixed percentile
options are problematic for extreme body forms, such as those derived from all P5 or P95 values. When
sitting height and leg length are P5, height is smaller than P5. Though such a problem is well recognized,
there is no consensus on the method for obtaining measurements for body forms statistically
representing the variation in a population. Considering this lack of consensus, it was decided not to
present such data in this document.
6 Background information

6.2.3 Demographic data
For demographic data (e.g. gender, age), information on the following items is provided:
a) definition of the working age;
b) description of participants;
c) number of participants by gender;
d) 10-year age groups.
When more than one subgroup based on criteria other than the age and gender is involved, the
percentage of each subgroup is provided, if necessary.
6.2.4 Publication on the anthropometric research
The author, publication year, title of the publication and the name of publisher are provided when the
data have been published.
6.3 Representativeness of the sample
6.3.1 Sampling method
A description is given of the grounds on which the sample was judged to be representative of the
intended population. These include an examination of the sampling method and can also include
the comparison of height and weight in the measured sample data with those from a large sample
representing the intended population. If the data need to be weighted in order to be representative,
then the weighting method is described.
6.3.2 Information on secular change
When significant secular changes are going on, information on the rate of change over the past few
decades is presented, when available, and appropriate references are given.
6.4 Accuracy and reliability of measurements
6.4.1 Skill of measurers
The number of measurers and information on the skill of each measurer, such as intra-observer mean
absolute difference or technical error of measurement (TEM) or repeated measurements, are shown
when such data are available. When more than one measurer is involved, the methods used to control
the quality of the measurement technique are documented. When the research is continued for more
than one month, the method of quality control during the research period is documented.
6.4.2 Measurements from 3-D scanners
When measurements are extracted from 3-D scans, the results are compared to measurements obtained
by traditional methods using the procedures in ISO 20685-1:2018, Clause 5. Similarly, measurements
taken using instruments not described in ISO 7250-1 are compared to those obtained by traditional
methods.
7 Procedure for presenting member body statistics
7.1 General

7.2 Submission of data
Users of this document and ISO member bodies are encouraged to submit anthropometric data for
this document. Users with knowledge of additional anthropometric data can contribute by contacting
their ISO member body and copying the ISO/TC 159/SC 3 secretariat on the communication (e-mail
addresses can be found on the ISO website: https:// www .iso .org/ ). Member bodies can contact
the ISO/TC 159/SC 3 committee manager directly. When information is received, it is processed as
described in this clause.
7.3 One data set from each member body
In the case of countries with more than one possible database, the member body determines which of
the databases is to be used. If more than one set of statistics is submitted, the member body will be
asked to choose only one data set.
7.4 Meeting the criteria outlined in 5.2, 5.3 and 5.4
Member bodies will provide summary statistics that meet the criteria outlined in 5.2, 5.3 and 5.4. If the
criteria are not met on the first submission, the member body will be asked to resubmit the statistics
according to the criteria.
7.5 Examination of possible errors
7.5.1 General
Recognizing that errors can accidentally occur in any data set, the submitted summary statistics are
examined for reasonableness. The steps used are those in 7.5.2 to 7.5.5.
7.5.2 Minima and maxima
The minima and maxima for each dimension are examined, comparing them to minima and maxima
from other member body submissions. If minima or maxima are likely to be the result of errors, the
member body will be contacted to verify the submission.
7.5.3 Percentile values
The distance of the P1 and P99, P5 and P95 from the P50 percentile value are examined. If the distant
percentiles are unusually distant from the P50, the member body will be contacted to verify the
submission
7.5.4 Standard deviation (SD)
The SD is compared to the SD submitted by other member bodies. If the SD is unusually large or
unusually small, the member body will be contacted to verify the submission.
7.5.5 Comparison of mean or P50 values from member bodies
The mean or P50 values are examined with respect to mean or P50 values from other member bodies
to make sure that the dimension being reported is that described in ISO 7250-1. If it appears that a
different measuring technique, or different measurement definition, has been used, the member body
will be contacted to verify the measurement procedure.
7.6 Marks on values likely to be in error
If resubmitted summary statistics are still likely to be in error, the published values are marked with a
footnote.
