Correct sitting posture for desk work
Correct sitting posture is not a frozen pose. It is a comfortable working position that lets your head, shoulders, arms, wrists, hips, and feet stay supported while you still change position through the day.
Short answer
Correct sitting posture starts with the screen directly in front of you, your head generally aligned with your torso, shoulders relaxed, elbows close to your body, wrists straight, back supported, and feet supported. The best sitting posture is also adjustable: you should change position and take breaks instead of trying to hold one rigid pose for hours.
What is the basic correct sitting posture?
Start from the screen and work outward. The monitor should be in front of you, easy to read, and at a height that does not make you crane your neck. Your head should feel balanced over your torso rather than reaching toward the display.
Let your shoulders relax. Keep elbows near your body. Keep wrists mostly straight and in line with your forearms. Support your lower back without sliding forward in the chair. Keep feet on the floor or a stable footrest.
This is a starting point, not a law. OSHA workstation guidance describes multiple neutral working postures because real work changes. Sitting upright, reclining slightly, and shifting position can all be reasonable if your body is supported and the setup fits the task.
The test is simple: can you keep working without effortfully holding the position? If the posture only works while you think about it, something may be misaligned. Adjust the chair, screen, or input devices until the supported position feels like the default rather than a performance.
How should your monitor be positioned?
Your monitor position can make or break sitting posture. If the screen is too low, your head drops. If it is too far away, you lean forward. If it is off to the side, you twist. If text is too small, your neck and torso become the zoom function.
Put the main screen directly in front of you. Adjust height and distance until you can read comfortably while staying relaxed. If you use two screens, put the primary one centered and keep the secondary close enough that you are not repeatedly turning your neck.
For laptop work, the screen and keyboard create a tradeoff. A laptop low enough for typing is usually too low for the neck, while a laptop high enough for the eyes is usually too high for the hands. For long sessions, raise the laptop and use separate input devices.
What should you do with your keyboard and mouse?
The keyboard and mouse should let your arms stay close. If the mouse is far to one side, one shoulder often rounds or reaches. If the keyboard is too high, your shoulders may lift. If the desk edge forces your wrists upward, typing can become uncomfortable.
Bring input devices close enough to use without reaching. Keep wrists straight when possible. Use shortcuts or sensitivity settings if constant mouse travel pulls your arm away from your body.
If you use a laptop keyboard, notice whether the screen height and hand position are fighting each other. Raising the laptop improves the screen but makes the built-in keyboard impractical. That is why a separate keyboard and mouse are often the cleaner long-session setup.
How often should you change sitting posture?
Often enough that you do not wait for discomfort to remind you. A small reset every 30 to 60 minutes is a practical starting point. Stand, walk, recline slightly, adjust the chair, or change tasks.
The mistake is treating correct sitting posture as a statue. Better posture is dynamic. You are trying to reduce long, repeated strain, not win a stillness contest.
If breaks are hard to remember, attach them to workflow moments: after sending a batch of email, before a call, after a build finishes, or between focus blocks. A repeatable cue is more reliable than promising yourself you will notice when posture gets bad.
Micro-adjustments count too. You can slide the keyboard closer, change the chair recline, plant both feet again, or stand during a short call. These small changes prevent one position from becoming the only position your body experiences all afternoon.
How does WorkPose check sitting posture?
WorkPose checks the visible posture signals your camera can see and turns them into a score. A front scan can show shoulder symmetry, arm position, and wrist alignment when visible. A side scan can add context for neck angle and torso lean.
That makes sitting posture easier to tune. Adjust the monitor, chair, keyboard, and mouse. Run the scan. If the same posture signal keeps showing up, you know where to keep working.
For example, if the front scan keeps showing uneven shoulders, look at mouse position and arm support. If a side scan shows repeated torso lean, check screen distance and laptop height. The scan gives you a concrete next experiment instead of another vague reminder to sit better.
When is sitting posture not enough?
If you have persistent or worsening pain, injury-related symptoms, numbness, tingling, weakness, or pain that radiates, do not rely on sitting advice alone. WorkPose provides ergonomic coaching, not diagnosis or treatment.
Also remember that sitting posture is only one part of the day. Sleep, stress, training, commute time, and total workload can all affect how your body feels. If the desk looks good but symptoms continue, widen the investigation instead of endlessly tweaking chair height.
FAQ
Should my back be perfectly straight?
No. Your back should be supported and comfortable. A slight recline can be fine if your screen and arms are still positioned well.
Should my feet touch the floor?
Your feet should be supported, either by the floor or a stable footrest, so you are not sliding forward or dangling.
Is a standing desk better than sitting?
A standing desk can help you vary posture, but standing still all day is not the answer. Alternating positions and moving matters more.
Can a posture scan replace an ergonomic assessment?
No. A scan gives useful visible feedback, but a professional ergonomic assessment can account for more context and symptoms.
