Typing is one of the most repetitive physical activities in modern life. Without proper ergonomics, it can lead to carpal tunnel syndrome, tendinitis, and chronic back pain.
Posture Fundamentals
Chair Height Your feet should be flat on the floor, thighs parallel to the ground. If your chair is too high, your wrists will flex upward; too low, and your shoulders will hunch.
Monitor Position The top of your monitor should be at or slightly below eye level, about an arm's length away. This prevents neck strain from looking up or down.
Keyboard Placement Your keyboard should be at elbow height or slightly below. Your forearms should be parallel to the floor, and your wrists should be straight — not angled up or down.
Wrist Alignment
The single most important ergonomic rule: keep your wrists neutral. This means: - No bending upward (extension) - No bending downward (flexion) - No angling sideways (ulnar or radial deviation)
A wrist rest can help, but only use it between typing bursts — don't rest your wrists on it while actively typing, as this creates pressure on the carpal tunnel.
The 20‑20‑20 Rule
Every 20 minutes, look at something 20 feet away for 20 seconds. This reduces eye strain and gives your hands a micro‑break.
Stretching Exercises
Perform these stretches every hour: 1. Finger spreads: Spread all fingers wide, hold for 5 seconds, release. Repeat 5 times. 2. Wrist circles: Rotate each wrist slowly in both directions, 10 circles each. 3. Prayer stretch: Press palms together in front of your chest, lower them until you feel a stretch in your forearms. Hold 15 seconds. 4. Shake it out: Let your hands hang loose and shake them gently for 10 seconds.
Ergonomic Keyboards
Split keyboards (like the Kinesis Advantage or ZSA Moonlander) position each hand independently, reducing ulnar deviation. They have a steep learning curve but offer significant long‑term comfort benefits.
The Bottom Line
Ergonomics is not optional — it is an investment in your typing longevity. A few small adjustments to your setup today can prevent painful injuries tomorrow and help you type faster with less effort.
