How to Set Up Your Desk to Stop the 3 p.m. Backache

Reviewed by Dr. Dustin Dukart, DC

If your back and neck are fine in the morning and sore by mid-afternoon, the setup you’re sitting in for those hours is a good place to start. Here’s a ten-minute pass through a workstation, with the actual targets.

Before the checklist: even a perfect workstation held for four hours straight will ache. The single most effective change is a brief position change every 20–30 minutes — the setup below matters, but it’s not a substitute for moving.

Work Bottom to Top

Chair height: feet flat on the floor (or a footrest), thighs roughly parallel to the floor or hips slightly higher than the knees.
Low-back support: your lower back should meet the chair’s curve — add a small cushion or rolled towel at belt level if it doesn’t. Sit back into the chair, not perched on the front edge.
Elbows: shoulders relaxed, elbows close to your body and bent to roughly 90–100°, forearms about level with the desk or keyboard. Drop or lower the armrests if they push your shoulders up.
Keyboard and mouse: directly in front of you, close enough that you’re not reaching. Wrists straight and floating, not bent up or resting hard on an edge while typing.
Monitor distance: about an arm’s length away.
Monitor height: the top of the screen at or just below eye level, so your gaze drops slightly to the middle of the screen and your head stays balanced over your shoulders. Raise it on a stand or books. Bifocal wearers: a bit lower.
Laptop: a laptop can’t meet both the screen-height and elbow targets at once — use a stand plus a separate keyboard and mouse for anything longer than a quick task.
Phone: a headset or speaker for calls, so you’re not pinning it with your shoulder.

The Setting That Beats Any Setup

Even a perfect workstation held for four hours straight will ache. The single most effective change is a brief position change every 20–30 minutes — stand for a call, walk to refill water, do a few backbends. “The best posture is your next posture.”

If It Still Hurts

If the afternoon ache doesn’t improve after a week or two of a better setup and regular breaks, or it’s spreading into an arm or leg, book an exam. Seek prompt medical care for numbness in the saddle area, new limb weakness, or any loss of bladder or bowel control.
