Ergonomic Desk Setup FAQ
Everything you need to know about setting up an ergonomic workspace, preventing pain, and optimizing your desk height for sitting or standing.
The correct ergonomic desk height is typically at your elbow height when your arms are bent at a 90-degree angle and your forearms are parallel to the floor. For most people, this is approximately 42.5% of their total height for a sitting desk, or 62.5% of their total height for a standing desk.
Your ideal chair seat height is the distance from the floor to the back of your knee. Ergonomically, this is approximately 25.3% of your total height. When seated, your feet should be flat on the floor with your knees bent at a 90 to 100-degree angle.
The top of your monitor screen should be at or slightly below eye level, about 50-60 cm above your desk surface for sitting, and 60-70 cm above your desk for standing. This prevents neck strain and encourages a neutral spine posture.
Both have benefits, but alternating between the two is best. Prolonged sitting is linked to health issues, while standing all day can cause leg and back fatigue. Ergonomists recommend a 1:1 or 1:2 ratio of sitting to standing, switching every 30 to 60 minutes.
Experts recommend switching positions every 30 to 60 minutes. A good rule of thumb is to stand for 15-20 minutes for every 45-60 minutes of sitting. Listen to your body and adjust based on your comfort and energy levels.
The 90-90-90 rule is a standard ergonomic guideline for sitting at a desk. It states that your ankles, knees, and elbows should all be bent at approximately 90-degree angles. Your hips should also be at a 90 to 100-degree angle, with your feet flat on the floor and forearms parallel to the desk.
