Calculator Inputs
Formula Used
The calculator estimates eye height as body height multiplied by 0.936 when a direct eye measurement is not supplied. It estimates standing elbow height as body height multiplied by 0.625 when an elbow measurement is not supplied. Shoe height and mat thickness are added to both references.
Keyboard top height = elbow height - tan(forearm angle) x forearm length.
Desk surface height = keyboard top height - keyboard thickness + keyboard tray drop.
Monitor top height = eye height - preferred eye drop. Screen height is calculated from diagonal size and aspect ratio. Monitor center equals monitor top minus one half of screen height.

A Practical Standing Desk Setup Guide
A standing desk works best when each surface matches your body, not a catalog size. This calculator turns simple measurements into practical targets. It estimates desk height, keyboard height, monitor center, screen distance, and break timing. The goal is a neutral posture that feels easy to repeat through the day.
Why Body Measurements Matter
The main reference point is standing elbow height. When shoulders stay relaxed, elbows should bend near ninety degrees. The keyboard surface is usually placed slightly below that point. A small forearm angle can reduce wrist extension. Shoes, desk mat thickness, and keyboard tray thickness also change the final number. That is why the form includes each detail.
Monitor Height and Distance
Monitor placement uses eye height and viewing distance. The top of the screen should sit near, or slightly below, eye level. The screen center is lower because the eyes naturally look down a little. Larger screens need more viewing distance. The calculator estimates top height, center height, and a comfortable distance range.
Movement and Work Cycles
Good standing work also depends on movement. No desk height solves fatigue alone. The tool adds a sit stand cycle from your planned standing share. It also suggests micro breaks and posture checks. These reminders help reduce static loading in the legs, back, neck, and shoulders.
Fine Tuning the Setup
Use the numbers as a setup guide, then test them in real work. Raise or lower the desk in small steps. Keep wrists straight. Keep shoulders loose. Put the mouse close to the keyboard. Place the screen directly ahead. Use an anti fatigue mat when standing for long periods.
Records and Adjustments
The result report is useful for office setup, remote work, workstation audits, and shared desks. CSV export helps compare several users. PDF export creates a quick record for installers or safety notes. The example table shows common outcomes for different heights.
Personal Limits
Ergonomics is personal. Pain, injury, bifocal lenses, task type, and equipment shape can change ideal settings. Treat the output as a strong starting point. For continuing discomfort, ask a qualified ergonomics or health professional for an individual assessment.
Measurement Consistency
Because measurements are entered in one unit system, results stay consistent. You can switch between centimeters and inches before calculating. Record actual desk limits too, since motors, casters, arms, and accessories can restrict adjustment range safely later.
FAQs
1. What height should my standing desk be?
Your desk should place the keyboard near relaxed elbow height. Wrists should stay straight, shoulders should stay loose, and elbows should bend near ninety degrees.
2. Should the keyboard sit on the desk surface?
It can sit on the desk if the desk adjusts low enough. If the surface is too high, use a tray so the keyboard top matches elbow height.
3. Where should my monitor top be?
The top of the screen is commonly placed near eye height or slightly below it. The calculator lets you set a preferred downward eye drop.
4. How far should the screen be?
A larger display usually needs more distance. The tool estimates a range from diagonal size, then compares it with your current viewing distance.
5. Is standing all day better than sitting?
No. Long static standing can also cause fatigue. A balanced cycle of sitting, standing, and walking is usually more comfortable.
6. Do shoes and mats affect desk height?
Yes. Shoes and standing mats raise your body above the floor. The calculator adds those values to eye and elbow references.
7. Why does forearm angle matter?
A slight downward forearm angle can keep wrists neutral. Too much angle can create strain, so the calculator limits the input range.
8. Can I export the result?
Yes. Use the CSV button for spreadsheets. Use the PDF button for a simple report you can save, print, or share.
