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 95% percentile indicates that 95% of people are smaller than the sizes given.
Therefore the size range show the mid 90% 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.
