What desk and chair height actually fits you
Enter your height. These are the numbers to set things to before you start adjusting by feel.
| Measurement | Range | Why |
|---|---|---|
| Desk surface, seated | 28–30 in | Keyboard at elbow height with your shoulders relaxed. |
| Desk surface, standing | 42–44 in | Same elbow rule, standing. Set this once and save the preset. |
| Seat height | 17.5–19 in | Feet flat, thighs roughly parallel to the floor. |
| Top edge of the screen | 49–52 in | At or just below seated eye level, about an arm’s length away. |
Why these are ranges and not one number
Two people the same height can have very different leg-to-torso proportions, so a single figure implies a precision that stature alone cannot support. Start in the middle of the range, work for a day, then move in half-inch steps.
What to change first if it still feels wrong
Set the seat first, then the desk to your elbows, then the screen to your eyes — in that order. Adjusting the screen to fix a seat problem is how people end up craning. If your feet do not reach the floor once the desk is right, you need a footrest, not a lower seat.
None of this replaces standing up every hour, which does more for your back than any number on this page.
