Standing vs. Sitting Heights

Your desk needs to be at the right height for both sitting and standing. Here's how to calculate the perfect height for each.

Standing Desk Height

YourHeight × 0.62

When standing, your desk should be at elbow height. This allows your arms to rest naturally at your sides with elbows at a 90-degree angle.

Example for 6'0" (183cm):

44.6"

113cm

72" × 0.62

= 44.64"

Key Points:

Feet flat on floor, shoulder-width apart
Elbows at 90-100 degree angle
Wrist rest should be level with keyboard

Sitting Desk Height

YourHeight × 0.40

When seated, your desk should be at waist height. This accounts for the seated posture with proper chair adjustment first.

Example for 6'0" (183cm):

28.8"

73cm

72" × 0.40

= 28.8"

Key Points:

Feet flat on floor, thighs parallel to ground
Chair adjusted first (seat height, lumbar)
Desk height measured from floor to surface
Critical for Neck Health

Monitor Positioning Guide

The most common ergonomic mistake? Monitor at the wrong height. Here's how to get it right.

1. Eye Level at Top 1/3

The top of your monitor should be at or slightly below eye level. When you look straight ahead, your eyes should be aimed at the top third of the screen.

Why? This allows you to look slightly down at the screen, which is the natural resting position for your eyes.

2. Arm's Length Away

Position your monitor about one arm's length away (20-26 inches). You should be able to touch the screen with your fingertips.

Why? This distance reduces eye strain and prevents you from leaning forward to see details.

3. Center the Screen

The center of your monitor should be directly in front of you. If using multiple monitors, the primary screen goes in front, secondary to the side.

Why? Prevents neck twisting and promotes symmetrical posture throughout the day.

Monitor Height Formula

Monitor Top Height = Height × 0.93 (Eye Level)

Your monitor top should be at eye level when standing

1

First, set your standing desk height

2

Multiply by 0.85

3

Adjust monitor arm/stand to that height

Keyboard & Mouse Placement

Proper keyboard and mouse positioning prevents wrist strain, carpal tunnel, and shoulder pain.

Keyboard Position

At Elbow Height

Keyboard surface should be at or slightly below elbow level when arms hang naturally at sides.

Flat or Slightly Negative Tilt

Keep keyboard flat or tilt it away from you (negative tilt). Avoid tilting it toward you—this causes wrist extension.

Centered with Your Body

The B key should be aligned with your belly button or nose. This keeps your wrists in a neutral position.

Keep Mouse Close

Mouse should be right next to keyboard at the same height. Reaching for the mouse causes shoulder strain.

Mouse Position

Same Level as Keyboard

Mouse pad should be on the same surface as the keyboard at the same height.

Directly Beside Keyboard

No gap between keyboard and mouse. Elbow should stay close to your body when moving the mouse.

Wrist Rest Optional

If using a wrist rest, only rest your palm during pauses—not while typing or clicking.

Consider a Trackball

If you have shoulder issues, a trackball keeps your arm stationary while you navigate.

Pro Tip: The T-Rex Arm Test

Rest your arm at your side with elbow bent at 90 degrees. Your forearm should be parallel to the floor. Can you comfortably reach your keyboard and mouse in this position? If not, adjust your desk height or consider an keyboard tray.

The Complete Picture

Lighting & Environment

Your environment affects more than just your mood—it impacts eye strain, focus, and long-term vision health.

Natural Light

Position your desk perpendicular to windows. Direct sunlight on screen causes glare; light from behind causes you to squint.

Screen Brightness

Match screen brightness to your surroundings. If walls are bright, turn up brightness. At night, use night mode or blue light filters.

Task Lighting

If reading documents, use a desk lamp. Position it to illuminate papers without creating screen glare. Aim for 500 lux at desk level.

Reduce Glare

Use anti-glare screen filters if needed. Matte screens reduce reflections. Adjust monitor angle to minimize window reflections.

Temperature & Air Quality

The ideal office temperature is between 68-72°F (20-22°C). But it's not just about temperature—air quality matters too.

  • Keep plants nearby—they improve air quality and reduce stress
  • Open windows for fresh air every few hours
  • Consider a small air purifier if ventilation is limited

The 20-20-20 Rule

Every 20 minutes, look at something 20 feet away for 20 seconds. This reduces eye strain and helps prevent digital eye fatigue.

Common Ergonomic Mistakes

These setup errors cause most desk-related pain. Fix them and feel the difference immediately.

Don't

Monitor at Chest Level

Looking down at a low monitor causes neck flexion and upper back strain. The fix: raise it to eye level.

Don't

Keyboard Too High

Shoulders hunching up to reach keyboard causes neck and shoulder tension. Elbows should be at 90 degrees.

Don't

Reaching for Mouse

Mouse on a different surface or too far away causes shoulder and elbow strain. Keep it adjacent to keyboard.

Don't

No Lumbar Support

Slouching in chairs without support leads to lower back pain. Use chair lumbar support or a pillow.

Don't

Sitting All Day

Static sitting—even with perfect posture—causes circulation issues. Alternate sit-stand every 30-60 minutes.

Don't

Glare on Screen

Squinting at screens with glare causes eye strain and headaches. Position monitor perpendicular to windows.
