Quick answer: The correct monitor position according to Ergonomics principles is to have the top edge of the screen at or slightly below eye level, with the center of the screen 15-30° below your line of sight. The screen should be approximately 50-70 cm away (about an arm's length). Using an adjustable monitor arm solves the common problem of screens being too low, which causes neck strain and eye fatigue.
Why Monitor Height and Distance Matter for Your Health
Many people assume that a large screen or high resolution is enough, but the correct monitor position is the deciding factor in whether you can work comfortably for eight hours. When the screen is too low, users subconsciously lean forward and hunch their necks. This causes cumulative tension in the neck and shoulder muscles, potentially leading to chronic pain or what is commonly known as Office Syndrome.
Conversely, if the screen is too far away or too small, you tend to lean in to read text clearly. This unnecessarily strains your eye muscles and neck. Understanding basic Ergonomics is one of the most valuable investments in your long-term health.

The Correct Monitor Position According to Ergonomics
To achieve the most comfortable working posture, you should adhere to these physiological guidelines for screen placement:
- Height: The top edge of the screen should be at eye level or slightly below. This allows your eyes to look slightly downward when viewing the center of the screen (which should be 15-30° below eye level). This slight downward gaze helps keep eyelids partially closed, reducing dry eyes.
- Distance: The screen should be approximately 50-70 cm away, roughly one arm's length. If your screen is larger than 27 inches, you may need to increase the distance slightly to maintain an appropriate field of view without straining.
- Tilt: The screen should be tilted slightly upward by about 10-20° to reduce glare and allow your eyes to meet the screen at the most comfortable angle.
Why Laptops Hurt Your Neck
The biggest problem for laptop users is that the screen height is inherently too low to adjust to ergonomic standards. Placing a laptop on a desk means the top edge is well below eye level. If you raise the laptop to meet eye level, the keyboard becomes too high, forcing you to shrug your shoulders. Both scenarios harm your body. Separating the screen and keyboard is the only effective solution.
Tools for Adjustment: Why You Need a Monitor Arm
The most direct and cost-effective solution is using equipment designed specifically for this purpose, especially a Monitor Arm. These arms allow you to adjust the "monitor height" exactly as needed.
For those looking for value and flexibility, we recommend the ERGONOZ Core Single Monitor Arm at ฿1,290. This popular model perfectly addresses the need for correct monitor positioning with these features:
- Supports screens from 17-32 inches and weights of 2-9 kg.
- Offers wide Tilt adjustment of ±90°.
- Includes Swivel ±90° and Rotation ±180°.
- Easy installation via Clamp or Grommet, with built-in cable management.
Using a monitor arm allows you to align the screen edge with your eye level immediately, without relying on books or boxes to prop it up. This is not only safer but also saves valuable desk space.
Comparing Different Monitor Placement Methods
| Placement Method | Health Drawback | Better Solution |
|---|---|---|
| Placing Laptop on Desk | Neck must bend significantly, causing neck and shoulder pain. | Use a Stand to elevate the Laptop + separate keyboard. |
| Using Original Stand | Limited height adjustment; rarely fits individual heights. | Use a Monitor Arm to align screen top with eye level. |
| Screen Too High | Requires looking up, causing nape pain and dry eyes. | Adjust Arm so screen is slightly below eye level. |
Frequently asked questions
Where should the top edge of the screen be?
The top edge of the screen should be at eye level or slightly below. This allows your eyes to look down about 15-30° when viewing the center, which is the angle where eye and neck muscles work the least.
How many centimeters should the screen be from your eyes?
The appropriate distance is 50-70 cm, or about one arm's length. If the screen is larger than 27 inches, you should slightly increase the distance to ensure the field of view is covered without causing eye strain.
How to set up if using only a laptop?
If using only a laptop, buy a Stand to elevate the laptop so the top edge is at eye level. You must also use a separate keyboard and mouse; otherwise, your shoulders will ache from raising your arms to type.
Why is a Monitor Arm better than the original stand?
Original stands often have limited height adjustment or cannot fine-tune the tilt. An arm like the ERGONOZ Core helps you find the position that fits your body precisely.
The bottom line
Adjusting your "correct monitor position" is the most valuable investment in your health. Aligning the screen top with eye level and keeping it one arm's length away effectively reduces neck and eye pain. For flexibility in height adjustment, consider ERGONOZ Monitor Arms which solve this directly (Free shipping on orders over ฿800 in Thailand).
