How to Play – Secrets of PC Gaming Ergonomics

1 – Adjust your Keyboard

Your keyboard should sit on a surface about 2-3 inches above your knees, and a pull-out drawer or shelf on your desk is absolutely ideal for that. For an easy reference point, the “g” and “h” keys should be right in line with your bellybutton. Make sure your keys are easy to press: having to hit your keys hard to make them respond puts far too much stress on the tendons of the small muscles of your hands and fingers.

When it comes whether or not your keyboard should have wrists rests, consider the following: keyboards with wrist rests increase pressure on the carpal tunnel up to 200% greater than keyboards without, which can lead to significant inflammation and nerve compression. If you absolutely HAVE to have something there for support, position it so that the base of your palm rests on it rather than your wrists. To further relieve stress on your wrists and keep them in a relaxed, neutral position, have good arm support (see item #4 – The Right Chair) and set up your keyboard so that it is angled down and away from you. Consider propping it so that the near side of your keyboard is about an inch or two higher than the far side of your keyboard. As usual, tweak it to find what’s most comfortable for you.

2 – Mouse Position

Just like your keyboard, your mouse should be on a surface about 2-3 inches above your knees. It should be directly in front of your shoulder or very slightly outside; you shouldn’t have to reach out in order to move it. The motion to control your mouse should come from the elbow, not from the wrist.

3 – Monitor Distance and Height 

Optimal visual range is within about 1-2 feet away from your face, with the center of the monitor about 15-30 degrees below your line of sight. You want to avoid hunching to look down at a screen, craning to look up at a screen, or straining to focus on a screen that’s too far away or too close. If you’re a taller individual, consider stacking books or a small box under your monitor to get it to the best height for you. Additionally, consider f.lux–it’s a program that automatically adjusts the amount of blue light emitted from your screen to match your circadian rhythms and reduce eyestrain.

4 – The Right Chair

Picking the right chair can be tricky. There are plenty of potential pitfalls: too skinny, and it puts pressure on your shoulder blades; too wide, you’ll find yourself twisted or tilted; too tall, you’ll end up hunching forward to avoid bumping your head; too short, and you won’t get the full back support you need. You could get a custom ergonomic gaming chair, but those are pretty expensive and not in most budgets. However, it matters less that you have the ideal “ergonomic” chair and matters more than whatever chair you have is comfortable, gives you adequate support, and is appropriate for your size. There are a couple of general criteria your chair should meet that will let you achieve those three things.

First, armrests are a must–supporting your forearms and elbows reduces stress on your shoulders, upper back, and neck. The armrests should let your arms be level with your bellybutton, and your keyboard/mouse should be around that height as well.

Second, your chair should be at a height that allows you to meet the required monitor height and mouse/keyboard position while still allowing you to have both feet on the floor with your knees bent to whatever extent is comfortable to you (usually between 90-120 degrees). If you’re on the shorter side, this is quite a tall order for your chair. Luckily, the fix is pretty easy–try placing a stool, a box, or one of those textbooks you bought for $200 that the campus bookstore will only give you $3.75 on buyback under your feet. This takes a significant amount of stress off of your back.

Third, you’ll need good lumbar support. If your chair doesn’t have good lumbar support–that is, support for your low back that helps it keep its natural curve–it’s easy enough to make your own with a small pillow or rolled/folded towel. Adjust to whatever is comfortable.

Finally, if you have multiple monitors or a large desk, you’ll want a chair that rolls, swivels, or does both; this prevents unnecessary twisting strain on your spine.

5 – Posture, Posture, Posture 

There’s a fairly popular study by Wilkes et al (1999) found that sitting at 90 degrees was the position of most compressive stress on the spine, which increases the pressure on the discs between your vertebrae. From this, a lot of people have concluded that ideal posture involves leaning back. However, that doesn’t take into account that other positions will put stresses on other structures that support your spine–ligaments and muscles.

What’s best, in fact, is to start at 90 degrees, find your neutral posture, and then adjust your chair to support that. “Neutral posture” is what’s briefly demonstrated in the gif above: feet planted, pelvis not tilted, lower back in slight extension, chest elevated, and head over your shoulders. In all likelihood, your neutral posture will be 90 degrees or greater; thus the suggestion to start at 90.

When you sit, you want your core engaged–it keeps you from slumping. “Engaging your core” here means keeping some amount of tension or contraction in your abdominal and low back muscles. If you’re having a hard time picturing that, imagine your standard WWE championship belt: if the muscles are covered by that belt, those are muscles you want to engage while sitting. You don’t have to suck in your gut or keep your back rigid; just keep enough tension in those muscles that you don’t slide down in your chair.


Final Takeaway

Overall, your setup should allow you to be comfortable: head and back supported, shoulders relaxed, arms supported, wrists in neutral (not too bent in any direction–you should be able to make a straight line from your elbows to your fingertips), knees bent, feet on the floor.

Your setup will be unique to you, based on your size, equipment, and available space. You don’t have to have “perfect” ergonomics at all times. But if you can make a few small changes to your arrangement, you’ll find yourself in a much better position to keep your gaming pain-free.
