“It is not the strongest of the species that survives, nor the most intelligent, but the one most responsive to change.”
– Leon C. Megginson (inspired by Darwin)
Anthropometric fit
Chairs, desks, and input devices should be sized according to human measurements.
One-size-fits-all rarely fits anyone perfectly.
Using anthropometric data ensures your equipment is proportionate to you.
Monitor position and eye health
Center your screen at arm’s length, with the top at or slightly below eye level.
This reduces neck strain and helps mitigate digital eyestrain.
The “20-20-20 rule” is well-known, but refreshing — look away from the screen every 20 minutes at something 20 feet away for 20 seconds.
Keyboard and mouse alignment
Align your mouse and keyboard so your elbows stay close to your torso.
Minimizing shoulder abduction prevents tension in the upper body.
Some experts suggest a split keyboard to maintain a neutral wrist angle.
Desk surface height
Ideal desk height varies by individual.
Adjustable desks accommodate different body heights and posture preferences (including standing).
Even minor height mismatches can lead to cumulative strain over months or years.
Foot support
If your feet don’t rest flat on the floor, use a footrest.
This prevents leg fatigue and promotes better circulation.
Proper lower limb support can reduce lower back pain by improving pelvic alignment.
