Understand the number.
Keep the context.

Tools that get to the point

You can calculate a walking estimate, explore treadmill settings, translate steps into distance, or understand a body-composition calculation without creating an account. Example inputs help you get started; your own details make the estimate more relevant.

Open about our assumptions

We explain the equation behind each result and link to the underlying references. We distinguish a model from a measurement and avoid suggesting that a calculated number can describe every individual precisely.

Our guides are published under the StrideCalc editorial name. They are educational explanations, not medical assessments, and the initial content has not been independently reviewed by a clinician. Read the methodology for the details.

Your inputs stay in the calculator

Calculations run in your browser. We do not ask you to upload photos, create a health profile or send body measurements to our own database. See the privacy information for hosting and browser details.

A useful estimate begins with a clear question. Pick a tool, change one input, and see how the model responds.
