Anthropology & Average Human Body Measurements
Rank: Forum user

Afternoon all,
A long time ago a remember seeing a study, possibly from the US, regarding average body dimensions.
These dimensions are used for ergonomic design & also formed the basis of BS standards for guarding (e.g. the 850mm reach rule)
Does anyone have a copy of this or a similar report. I need to specifiy average height, waist height, shoulder height, head height etc. for a ergonomic project.
Regards, Ian

You need to get hold of something like 'bodyspace' by S Pheasant; try an inter-library loan. It contains data for several UK and non-UK populations.

PS - it's 'anthropometry'.

Suggest you use the current Brirish Standards/European Standards for your data source.
Sorry don't have the BS numbers with me at present, but there are quite a few standards that you might need to look at.
The Stephen Pheasant book is quite old, although very readable.
The data you use should relate to your population that yiu are interested in.
For example Dutch people tend to be very tall. Far Eastern people smaller,
Also some data relates to military personnel - who tend to be above average in terms of size fitness etc.
Be careful with your data source, if the decisions you make are safety critical/important.

Take a look at Loughborough University's excellenct website openerg.com. It's a fantastic resource for anthropometric data, their DSE section is fantastic - the self assessment is the best I've seen. And it's all free!
If you don't know this site, take a look. You'll be glad you did.

Steve Pheasant died in 1996 when the second edition of Bodyspace was published by Taylor and Francis.
A third edition was published with Christine Haslegrave as co-author in 2005 by CRC Press.
Both editions have copies of copious tables of anthropometric data on body segments, which Steve gathered for the BSI.

I should have added that the whole purpose of the data collected by Steve is to illustrate how INVALID and practically useless almost all 'average' measures of human bodies are.
His data range from the fifth to ninety-fifth percentiles of males and females, under and over 18, in British and other populations.

In support of Kieran's post, if anyone is wondering why designing just for the 'average' size person isn't good practice, it is quite common to find that a person may well be 'average' in overall height - but that individual part sof the body are not average.
i.e. someone could have relatively short legs, but a longer upper body - but still be an average overall height.
Likewise with forearms, fingers etc - all important stuff when designing plant controls, levers, reach distances, seats/foot controls etc.
As previous pick your data carefully, for the population that you are designing for.
Its common to design for the 5th-95th percentiles as Kieran indicates.
In the nuclear sector its usually the 3rd-97th percentiles of a population, in my experience.

During my training with HSE in the late 1970s when BS 5304 "Safeguarding of machinery" was the main general document used by inspectors (having been largely compiled by HM Factory Inspectorate, HSE's main predecessor, for the British Standards Institution), we were told that its content about permitted widths/sizes of apertures in guards in relation to distances from dangerous parts of machinery was not absolute. A classic example of this related to the fact that accident investigations had found that some young Asian women had fingers which were both longer and more slender than those of most women. I don't have ready access to detailed information about guarding standards, so can't advise if BS 5304 or its successors were suitably amended to take this fact into account.
