Terms of Use

Last updated: 2026-06-13

These terms govern your use of sewcalcs.uk (the “site”). By using the site you agree to these terms. If you do not agree, please do not use the site.

1. What the site provides

The site is a free library of sewing, dressmaking and quilting calculators plus reference content — covering fabric yardage and layout, seam allowances, pattern sizing and ease, curtains and blinds, quilting backing and binding, notions and thread. It is provided “as is” without account registration or payment.

2. Accuracy and your own measurements

Calculators are estimates based on standard fabric widths, established dressmaking practice, and the measurements and dimensions you enter. Real-world results depend on the specific fabric, its width, nap and pattern repeat, shrinkage, your pattern and the seam allowances and ease you use, and how the fabric behaves once cut. Always pre-wash and measure your actual fabric, check the pattern’s own yardage and finished measurements, and make a toile (test garment) for fitted pieces before cutting your main cloth.

Treat every result as a starting point, not a guarantee. Fabric quantities in particular vary with width, nap, pattern matching and layout, so buy a little extra from the same bolt and dye lot where you can. We round and estimate conservatively, but we cannot account for every fabric, pattern or project, so verify quantities and measurements against your pattern and your own cloth before you cut.

3. Limitation of liability

To the fullest extent permitted by law, we are not liable for:

indirect, incidental, or consequential loss arising from your use of the site;
loss of profits, revenue, goodwill, business interruption, or anticipated savings;
wasted fabric, mis-cut or mis-sized garments, or errors or omissions in calculator output;
out-of-date citations where fabric widths or sizing conventions have since changed;
third-party links and their content.

Nothing in these terms limits or excludes liability for death or personal injury caused by negligence, fraud, or any liability that cannot lawfully be excluded under English law.

4. Acceptable use

You agree not to:

scrape the site in bulk using automated tools faster than a reasonable human pace;
attempt to reverse-engineer, modify, or break the site’s services;
misrepresent the site’s content as official guidance or as an endorsement of a product;

5. Intellectual property

Page text, charts, UI design, calculator logic, and code are protected by copyright unless stated otherwise. You may:

view, save, and print pages for personal or internal business use;

You may not: republish substantial extracts, scrape at scale for training commercial AI systems, or present the site’s content as your own.

6. Privacy

7. Changes to these terms

We may update these terms when the law, our services, or our practices change. The “last updated” date reflects the most recent revision.
