Eye Height/Elbow Height Tables — The following tables provide eye height and elbow height data based on anthropometric data for the US population.

Anthropometric Data for Average Range of Users

*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.

Anthropometric Data for 90% of 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%.

*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.
