What is the correct ergonomic height for my desk, computer monitor and office chair?

, , ,

Time and again we get asked the same question….“what is the correct ergonomic height setting for my office chair?” The answer is not that simple because it depends on two main factors, namely your height, and the type of work that you do. Because every person and their job environment is unique, the correct height for your desk, monitor and office chair will fall within a range of values.

If you work at a desk doing ‘normal’ or ‘standard’ office work like writing or working on a computer, then the following guidelines are applicable for setting the correct ergonomic height for your office chair, desk and monitor.
