Ergonomics is the science of designing products, systems and environments for human use.
The main objective of ergonomics to the designer is to improve peoples lives by increasing their comfort and satisfacton when interacting with products, systems and environments.
To do this data about the size and shape of the human body is needed, this is called anthropometrics

Anthropometrics
Anthropometrics is a branch of ergonomics that deals with human measurements in particular their shapes and sizes.
Anthropometric data must take into account the greatest possible number of users, so this data exits in the form of charts which provides measurements for the 90% of the population that falls between the fith and 95th percentile

Applications of Anthropometrics
Anthropometric data is available from the British Standards Institute (BSI)
The 5th percentile is the size/dimension at which only 5% of the population is shorter than
The size/dimension that only 5% of the population is taller/larger than is called the 95th percentile
When designing a product the designer should ignore the 5th and 95th % and design the product to suit the 90% in between who make up the majority of the users
