Terms of Use
By using QuiltMath, you agree to use its outputs as planning estimates and to verify them for your specific project before buying or cutting fabric.
Planning estimates
Results depend on the measurements and assumptions you enter. Fabric width, shrinkage, print matching, cutting accuracy, pattern instructions, longarm loading and construction methods can change the amount you need.
Your responsibility
Measure the actual project, check your pattern and confirm professional quilter requirements. Consider purchasing additional fabric for prewashing, squaring, matching directional prints and mistakes.
No professional guarantee
QuiltMath provides general informational tools. It does not guarantee a specific result, eliminate waste or replace advice from a pattern designer, quilt shop or longarm professional.
Acceptable use
You may use the calculators for personal and commercial quilt planning. Do not interfere with the site, attempt unauthorized access or present QuiltMath outputs as an industry-mandated standard.
Availability and changes
Features, formulas and availability may change. The current formulas and assumptions are documented on the Methodology page.
