Terms of Use
Last updated: October 11, 2026.
Using the site
The calculator and worked examples provide general material-planning estimates. You may use the calculator without an account and print its output for your project.
Measurements and assumptions
Check your measurements, actual roll dimensions, overlap, strip direction, and product instructions before buying or cutting. Circle estimates use an enclosing square, L-shapes use two panels, and remnants are not automatically reused. Pin quantities cover the modeled boundary and seams only. No material or fastening suitability is certified for a particular site.
Availability and responsibility
The site is provided as available, without a guarantee of uninterrupted operation or suitability for every project. Project decisions remain dependent on measurements and conditions outside the calculator. These terms do not exclude rights or responsibilities that cannot legally be excluded.
Content and links
You may link to these pages and use their calculated quantities. Do not republish the complete website or present its content as your own. External sites control their own content and privacy practices.
Questions and updates
We may revise these terms and the calculator as the site develops. Send questions or reproducible error reports to hello@twocutweb.com.
