Terms of use

QuiltMath is free to use for planning your quilting projects. These terms keep things fair and clear for everyone.

Use of the calculators

You are welcome to use every calculator on this site for personal and professional quilting, free of charge, with no account. You may link to any page on this site; quilting guilds, longarm quilters, shops, and teachers are warmly encouraged to do so.

What you may not do

You may not copy the site's content, code, or calculators and republish them as your own, scrape the site at scale, or use the site in any way that disrupts it for others. Quoting reasonable excerpts with a link back is fine and appreciated.

No warranty

The calculators are provided "as is." We verify our formulas carefully (see the About page for how), but we cannot guarantee results for every fabric, pattern, or situation, and we are not responsible for fabric purchasing or cutting decisions made using this site. Always confirm measurements against your pattern before cutting; see our disclaimer.

Intellectual property

The QuiltMath name, design, content, and code are the property of King Winston Media. Standard quilting formulas themselves belong to everyone, as arithmetic should.

Changes

We may update these terms as the site evolves; the date below reflects the current version. Continued use of the site after changes constitutes acceptance.
