🖥️ Desk Height Calculator
Enter your standing height to get a recommended desk height that keeps your elbows near a 90-degree angle when typing — a quick sanity check before you buy or adjust a desk.
🧮 Find Your Desk Height
What is a Desk Height Calculator?
It converts your standing height into a recommended desk height using a common ergonomic rule of thumb, so your typing setup starts from a real number instead of whatever height the desk shipped at.
Use it before buying a desk, when adjusting a height-adjustable frame, or when troubleshooting wrist or shoulder discomfort at your workstation. Pair it with the seat height calculator so your chair and desk line up for a neutral, comfortable posture.
❓ Frequently Asked Questions
How does the desk height calculator work?
Enter your standing height in centimetres. It multiplies that figure by 0.42 — a common ergonomic rule of thumb — to estimate a desk height that keeps your elbows near a 90-degree angle when typing.
Why 42% of my height instead of a fixed number?
A fixed desk height suits an average-sized person but not everyone. Scaling from your own height accounts for taller or shorter frames, giving a more personal starting point than a one-size table sold at a standard height.
What if my chair doesn't match the recommended desk height?
Seat height and desk height should be set together. If your chair sits your thighs level but your elbows aren't near 90 degrees at the desk, look at an adjustable-height desk, a keyboard tray, or a footrest to bridge the gap rather than compromising either measurement.
Does this work for standing desks too?
The 0.42 rule of thumb is aimed at seated typing height. For a standing desk, most people set the surface a little higher — roughly elbow height while standing upright — so treat this result as your sitting-height reference point when you lower the desk.
