Terms of use

By using StairRunnerLengthCalculator.com you agree to these terms.

Estimates, not guarantees

The calculator and guides give estimates based on the measurements and options you enter. They are only as accurate as those measurements. Always have your fitter or supplier confirm quantities, joins, pattern matching and fitting details before you order or cut material.

No liability for orders

We are not responsible for material shortfalls, surplus, costs or fitting problems arising from use of the estimates. Prices you enter are your own and are not quotes from us.

Use of the site

You may use the calculator for personal and professional projects free of charge, including printing results for clients. Please do not copy the site's guides in bulk or misuse the site.

Availability

The site is provided as is. We may change or withdraw features without notice.
