How the screen, your reach and the light line up

Everyday, general-information notes on the small geometry of a desk: where the screen sits, how far you reach, and how light lands on your work.

Screen height

Eyes meet the top of the screen

A common starting point is to set the screen so the top of the display sits roughly level with your eyes when you look straight ahead. Many people find this lets the head balance comfortably rather than tipping down toward a low laptop.

A stack of books, a dedicated riser or an adjustable arm can all raise a screen. There is no single right height — adjust until looking ahead feels natural.

Comfortable reach

Keep the things you touch most close by

Where your keyboard, mouse and notes sit shapes how often you stretch or twist.

Keyboard distance

Sitting close enough that your elbows stay near your sides, rather than reaching forward across the desk.

Mouse beside it

Keeping the mouse or trackpad at the same level and within an easy arc of the keyboard.

Notes in view

Placing a notebook or second screen where you can glance across without a full turn of the neck.

Light & glare

Let daylight help, not hinder

Light has a quiet effect on how easy a screen is to read. Many people place the desk so a window sits to the side rather than directly in front of or behind the screen, which can otherwise wash out the display or cast a reflection.

  • A side-on window spreads daylight without glaring on the screen.
  • A soft desk lamp fills shadows on darker days.
  • Matching screen brightness to the room reduces strain on the eyes.

Posture variety

Movement matters more than one perfect pose

Rather than chasing one perfect pose, many people find it more useful to change position gently through the day.

  1. Shift now and then

    Easing between sitting upright, leaning back and standing keeps any single position from becoming the only one.

  2. Stand for short tasks

    Reading, calls or quick notes can be a natural moment to stand if your desk or a counter allows it.

  3. Step away briefly

    A short walk to refill a glass of water is an easy way to break up a long stretch at the desk.

Quick recap

A short checklist

  • Top of the screen near eye level.
  • Keyboard close, elbows relaxed by your sides.

  • Change position gently through the day.
