Anthropometric Data for Average Range of Users
Anthropometric Data for 90% of Population †
Eye Height/Elbow Height Tables — The following tables provide eye height and elbow height data
based on anthropometric data for the US population.
* Eye height/elbow height = distance from top of CRT monitor screen to keyboard tray—roughly 21".
** Workstation with 6" of vertical adjustability can provide optimum viewing height for the average range of female to
male operators in either a sitting or standing environment.
*** Workstation with 16" of vertical adjustability can provide a sit-to-stand workstation environment for a range of
average height persons. An adjustment range of 20" will cover the sit-to-stand range of average female to
average male operators, i.e. 64.4"–44".
The above tables provide mounting height data to set up a workstation for an average range of operators: average
female, average person or average male. If increased adjustability ranges are required, reference the tables below,
which provide anthropometric data for 90% of US population.
Note: Values do not include shoe height, usually 1" for males and 1/2" for females.
* Workstation with 12.9" of vertical adjustability can provide optimum viewing height for the 5% female to 95% male
population in either a sitting or standing environment.
** Eye/elbow height = top of CRT screen to keyboard tray.
*** To provide a sit-to-stand work environment for the complete 5% female to 95% male population requires a
workstation with 27.8" of vertical adjustability.
† “90% of Population” excludes the shortest 5% of females and the tallest 5% of males in the US population.
This entry denotes the female who is at the
5% mark of a scale ranging 0% to 100%.
This entry denotes the male who is at the
95% mark of a scale ranging 0% to 100%.
