Enter your height to get a recommended seated desk height and a matching chair seat height, based on standard ergonomic sizing charts.
Estimate only — arm length and typing posture vary from person to person.
We convert your height to inches if needed, then apply two linear formulas drawn from standard ergonomic sizing charts: desk height = 0.25 × your height + 9.5 inches, and chair seat height = 0.23 × your height. For someone 68 in tall, that works out to about 26.5 in for the desk and 15.6 in for the chair.
These ratios approximate seated elbow height — tall enough that your forearms rest roughly level while typing without hunching your shoulders — paired with a seat height that keeps your feet flat and knees near a right angle. A single "one-size" desk height of 28-30 in works reasonably for average-height adults, but scaling the formula off your actual height matters more the further you are from that average.
28-30 in is a common "one size fits most" desk height, but if you're notably shorter or taller than average, a height tailored to your own measurements — like the one above — is more comfortable.
Adjust the chair first to get your feet flat and knees near 90°, then use a footrest if your desk is too tall to also let your arms rest comfortably at that chair height.
