The best screen height for posture is achieved when the top of the screen is at or slightly below eye level. Your eyeline should be around 2 – 4 inches (5-10 cm) below the top edge of the screen. This setup allows you to view the screen comfortably without tilting your head up or down, which helps maintain a neutral neck position and reduces strain on your neck and shoulders. The center of the screen should be about 17-18 degrees below horizontal eye level to ensure optimal viewing and minimize eye strain. The monitor should also be placed at an arm’s length away from you to avoid leaning forward or backward.
