01 / Desk-height tool
Standing desk height calculator
Use your own elbow measurements as a starting reference for a sitting and standing work surface. This calculator copies your measurements into centimetres and inches; it does not estimate a height from body stature.
How to use the reference
Measure to the elbow line with your forearm roughly level, shoulders relaxed, and elbows bent near 90 degrees. The CCOHS sit/stand guidance places the standing platform approximately at standing elbow height; its chair-adjustment guidance recommends aligning elbows with a fixed work surface and using a footrest when needed. Your task, keyboard, shoes, and posture affect the setup.
For a seated reading, measure from the floor while using the chair and foot support you expect to use. For standing, include your usual work shoes. If the keyboard sits above the desktop, enter that vertical rise so the tool subtracts it from the elbow measurement.
This simple tool does not calculate chair seat height, monitor position, reach, clearances, accessibility, or medical needs. Adjust the setup to your work and comfort; ask a qualified professional about individual concerns.
