About CalculateWalk
CalculateWalk exists to answer the question every active person has asked: how much am I actually doing, and what does it mean? We publish a free walking calculator and thirty peer-reviewed evidence-based articles on the science of walking, training, health outcomes, and injury prevention. Everything here is grounded in published research and real-world field practice.
Our Mission
Walking is the most-practiced form of exercise on Earth. Yet walkers — unlike runners or cyclists — rarely measure their effort, pace, or progress. We believe that knowing your numbers transforms walking from a vague healthy habit into a trackable practice you can improve. CalculateWalk makes that measurement straightforward and the evidence behind it transparent.
Our Calculator: How It Works
MET-Based Calorie Estimation
Our calorie estimates use metabolic equivalent (MET) values from the Compendium of Physical Activities, the gold-standard reference used in exercise science and epidemiology. METs account for pace, body weight, and time to give you a science-grounded estimate of energy expenditure.
Step Count from Height
We estimate step count from your height using the biomechanical principle that average adult stride length is approximately 41% of height. This gives a personalized estimate without requiring device tracking.
Every formula used in the calculator is disclosed on this site. The tool runs entirely in your browser — distances, times, and weights you enter are never transmitted to our servers or stored.
Our Editorial Standards
CalculateWalk's 30 articles are fact-checked against:
- Published research: Studies from journals including JAMA Internal Medicine, Circulation, The Lancet, and International Journal of Epidemiology on walking's effects on cardiovascular health, weight, mental health, longevity, and injury risk.
- Government guidance: Recommendations from the U.S. Department of Health & Human Services, CDC, WHO, and similar organizations.
- Field practice: Real-world experience and testing from active walkers, fitness professionals, and exercise scientists.
Where evidence is mixed or evolving, we say so. Nothing on this site is medical advice — see our disclaimers on every page. We encourage you to talk to your doctor before starting any new exercise program.
Affiliate & Sponsorship Transparency
CalculateWalk is supported by:
- Google AdSense: Advertising on all pages.
