Disclaimer

Last updated: September 2026. Please read this page carefully before using our calculators.

Educational information only

All content on ErgoDesk — calculators, articles, tables, and examples — is published for general educational purposes. It is not ergonomic advice and is not a substitute for a qualified professional. We are not physician or physical therapists, and no client or advisory relationship is created by your use of this Site.

Ergonomic calculators fit equipment to population body dimensions — they reduce strain risk but cannot diagnose or treat pain. Numbness, radiating pain, or symptoms persisting beyond rest deserve a physician or physical therapist, not a different desk height.

Height-based formulas carry individual variation (torso vs leg proportions, shoulder width, existing conditions). Treat outputs as calibrated starting points and adjust to comfort within the stated ranges.

Accuracy of calculations

We implement well-known, publicly documented formulas (see the methodology section on each calculator page and published anthropometric data and OSHA/NIOSH ergonomics guidance as applicable). Even correctly implemented formulas produce estimates that depend on your inputs and assumptions. Real-world outcomes vary. Do not rely on a single web tool for a consequential decision.

Advertising disclosure

ErgoDesk is funded by display advertising served through Google AdSense. Advertisers have no influence over our content, formulas, or editorial choices, and placement of an ad is not an endorsement.
