When setting up your standing desk, it's crucial to find the right height for your optimal comfort and posture. To achieve this, start by standing with your feet shoulder-width apart and your arms relaxed at your sides. Your elbows should be at a 90-degree angle when typing, and the top of your monitor should be at or slightly below eye level. Adjust the desk height accordingly, and remember that it may take some trial and error to find the perfect fit.
