If you use the letters most, it makes sense to align yourself with that sectionthe "B" key should be about in line with your belly button.ħ. Letter keys are on the left and the numeric keypad is on the right, but most people center themselves with the entire keyboard or keyboard tray-not the letters! This puts the keyboard a little too far to the left. Stay centered on the lettered part of the keyboard. A wrist rest should be used to rest the heel of your palm, not your wrist itself.Ħ. Never use wrist rests or armrests while typing. If your workstation has wrist rests or armrests, be sure to use them only while taking breaks. Don't use wrist rests or armrests while typing-only while resting. If your chair has armrests, the armrests should comfortably support your elbows during rest breaks.ĥ. Your forearms should be roughly parallel to the floor. You shouldn't have to raise your shoulders to get your hands to reach the keyboard-try raising your chair instead. Keep your shoulders relaxed, and your elbows at your side. Adjust the height of your chair or your keyboard tray to achieve a comfortable position.Ĥ. Keeping your elbows bent less than 90° can cause nerve compression, leading to sore wrists and arms. Keep sure your elbows at a slightly open angle-90˚ or greater. When you're typing, your forearms tend to sag as the arms tire, putting the wrists into even greater wrist extension-another good reason to take frequent stretch or rest breaks!ģ. This can cause pain and lead to injuries like carpal tunnel syndrome. Repeatedly bending your wrists up and down (extension and flexion) compresses structures inside the carpal tunnel in the wrist. Keep your wrists in a neutral (straight) positionnot bent up or down. The tendons from your fingers connect near your elbow, so striking the keys too hard can lead to problems you might not associate with your keyboard-for example, pain and inflammation in your elbows (Epicondylitis).Ģ. Try to use the minimum amount of force necessary to depress the keys. Use a light touch when typing (don't bang on the keyboard!). Conversely, thinner people may find a traditional "straight" keyboard more comfortable.ġ. The outward angle lets your wrists and forearms point inward without requiring your elbows to come in as far, better conforming to the contours of your body. Split keyboards divide the keyboard into two halves, each of which points slightly outwards. If you have a broad chest, consider a "split" keyboard. Your mouse should be close to your keyboard so that you don't have to reach far to grasp it.ĥ. If you use a keyboard tray, make sure there's enough room for your mouse. Also, make sure that if there are "legs" attached to the bottom front of your keyboard, they are left un-extended.Ĥ. Try to avoid positive keyboard tilt (i.e., where the top row of keys is noticeably higher than the bottom row of keys). Using a slightly negative keyboard tilt will help you keep your wrists in the proper (neutral) position. If your keyboard is lower than the desk surface, tilt the back edge of the keyboard slightly down (known as "negative keyboard tilt"). (If you don't have an adjustable keyboard tray, you may need to accomplish this by adjusting your chair height).ģ. This is lower than most people normally place their keyboard, but lets your arms tilt downward while using the keyboard, leaving your elbows at a comfortable "open" angle. In the proper position, the keyboard should be placed just above the level of your lap. Make sure the height of your keyboard allows you to keep an "open angle" with your arms. Choose a system that is height adjustable, lets you tilt the keyboard away from you slightly for better posture (negative tilt), and allows you to use the mouse with your upper arms relaxed and as close to the body as possible.Ģ. This allows a much wider range of adjustment, and helps you maintain a proper ergonomic setup. If you don't currently use an adjustable keyboard/mouse tray, consider attaching one to your surface. That's why it's so important - even if you're not currently feeling pain-to position and use your keyboard properly to avoid future problems.ġ. These ailments can take years to develop, and once present, can be difficult or even impossible to reverse. There are a number of ailments that can come from using your keyboard incorrectly-from short-term issues like sore wrists to long-term problems like Carpal Tunnel Syndrome.
