How far should you really sit from your monitor?
Ergonomics guidance suggests adjusting screen distance, height and tilt based on monitor size to avoid eye strain and poor posture, with the simple 'arm's length rule' as a starting point.
Setting up a comfortable workspace involves more than a good chair and lighting — the distance, height and tilt of your screen relative to your eyes also matter. Sitting too close can cause eye strain and fatigue, while sitting too far away forces you to squint or lean forward, which can harm your neck and back over time.
The arm's length rule
The simplest way to gauge proper distance is to stretch out your arm — the monitor should be positioned so your fingers can just touch the screen. The generally recommended distance between eyes and display is 20 to 28 inches, which roughly matches the average adult's arm length.
More specific guidance depends on screen size. For 24-inch monitors, a distance of 20-28 inches works well, while 27-inch displays call for 24-32 inches. Monitors of 32 inches or larger need even more distance — around 34 to 38 inches — so the entire screen stays within the field of view without requiring neck movement. Higher resolutions allow sitting closer without seeing individual pixels, which is why many large 32-inch monitors ship with at least 1440p resolution. Laptop users are advised to pair their device with a separate keyboard and mouse to maintain proper distance, and to increase font size or display scaling if needed.
Height and tilt matter too
The screen should sit directly in front of you at eye level, with the top of the monitor at or just below eye height and the middle of the screen tilted 15-20 degrees below your eyeline. Adjusting chair or desk height, or using a laptop riser, can help achieve this — while making sure your feet remain flat on the floor. People who wear bifocals should position the monitor slightly lower to account for how they look through their lenses. Tilting the screen back 10-20 degrees is recommended, or 30-45 degrees for bifocal wearers. Adjusting brightness and using an anti-glare filter can further reduce eye strain, and the same guidelines apply to multi-monitor setups.
