This page provides notes relating to human sizes and links to sites providing data on human
measurements and interfaces.
The following data is for guidance and is not for detailed design.
In designing any equipment requiring manual handling one is advised to refer the
the relevant regulations. Refer to.
Useful Dimensions ..A page on this website with some useful human related dimensions
This data provides information on the sizes of British ?? people between the ages of 18 to 65.
It can only be used to give rough ideas of people sizes for the following reasons
The statistical sizes vary with age the average height for an elderly person would be up to 80mmm lower than that
for a younger person
People sizes vary significantly for different nationalities, i.e Americans are generally larger than
British who are larger than people from India.
Over time the average sizes of people change. If you are designing a doorway for the average person today it may be too small for the average person in 80 years time .
Over time the ethnic make up of a population can change e.g. in the UK at this time there is a rapid growth in the population
as people imigrate into the UK from overseas, Also the average population is aging. This could possibly result is a reduction in the average peoply sizes- contradicting 3) above
Importantly - the relevant target group may be significantly different to the general population.
Designing equipment for a basket ball team would require totally different set of data to that for the general population
The table relates to British person age 19 to 65 .
The 5% percentile indicates that 5% of people are smaller than the sizes given.
The percentile indicates that of people are smaller than the sizes given.
Therefore the size range show the mid range of people sizes in the UK. The average values is simply the mean of these to values
The data relates to people wearing the minimum of clothing and wearing no footwear. In height allowances it is prudent
to allow about 25mm for male shoes and about 45mm for female shoes.
The numbers I present in the table below are not directly obtained from any source. I have
referred to a number of information sources, which I identify, below and used interpreted/interpolated values.
These are of the top of my head values which I believe are just as relevant for general/rough use as formal statistical data derived from specific
groups at specific times, using specific methods. For formal design work requiring justification of data it is important
to use quality information such as The Openerg website Database Peoplesize -
This is probably the best current source of this information (at a cost). or DTI document "Adultdata" by L/Peebles/B Norris (1998) if you get hold of it - I referred to a copy about 2 years ago in my local library.
The table below is not based on any data included in these two reference sources.
