The optimal height for your sit-stand desk depends on your body measurements and ensuring ergonomic comfort. The guide to help you determine the correct height for both sitting and standing positions:

For Sitting Position

1. Desk Height: Your desk should be at a height where your elbows are bent at a 90-degree angle and your forearms are parallel to the ground when typing.

   • Typical Range: For most people, this is around 24 to 29 inches from the floor.

2. Monitor Height: The top of your monitor should be at or slightly below eye level.

   • Adjustability: Use a monitor stand or adjustable arm to achieve this.

3. Chair Height: Adjust your chair so your feet are flat on the floor, and your knees are at a 90-degree angle.

   • Footrest: If your chair is too high for your feet to reach the floor, use a footrest.

For Standing Position

1. Desk Height: Your desk should be at a height where your elbows are at a 90-degree angle and your forearms are parallel to the ground when typing.

   • Typical Range: For most people, this is around 35 to 47 inches from the floor.

2. Monitor Height: The top of your monitor should be at or slightly below eye level.

   • Adjustability: Use a monitor stand or adjustable arm to achieve this.

3. Foot Position: Keep your feet flat on the ground and consider using an anti-fatigue mat for added comfort.

Using Ergonomic Calculators

• Online Tools: There are online ergonomic calculators that can help you find the ideal desk height based on your height and body proportions.
• Measurements Needed: Typically, you need to input your height, the length of your lower and upper arms, and sometimes other measurements to get precise recommendations.

Adjusting Your Desk

• Electric Desks: If you have an electric sit-stand desk, use the programmable settings to save your preferred heights for sitting and standing.
• Manual Desks: If your desk adjusts manually, make sure you mark the correct heights for easy adjustment.

General Recommendations

• Sitting Desk Height: For someone around 5'11" (180 cm), a sitting desk height of about 29 inches (73.7 cm) is often comfortable.
• Standing Desk Height: For the same height, a standing desk height of about 44 inches (111.8 cm) is usually comfortable.
• Adjust According to Your Height: If you are taller or shorter, adjust the desk height accordingly. Use the 90-degree elbow rule as a guide.

Testing and Fine-Tuning

• Trial and Error: Once you set your desk, spend some time working to ensure it feels comfortable. Make any necessary adjustments.
• Feedback: Pay attention to any discomfort in your wrists, shoulders, neck, or back. These can be signs that your desk height needs further adjustment.

By following these guidelines, you can set up your sit-stand desk to ensure ergonomic comfort and improve your posture and overall work experience.
