What is the proper monitor distance for office desk planning?

NIOSH and ergonomic guidelines recommend monitor placement at an arm's length from the user (approximately 20–30 in., or 50–75 cm), with the top of the monitor at or slightly below seated eye level. For 27–32 in. wide monitors, the minimum desk depth is 30 in. to achieve proper viewing distance.
