King Quilt Calculator
Plan a king quilt using a common 108" × 108" finished size. King quilts are large projects, so backing width, batting size, and binding length matter before you buy fabric.

Formula
King quilt estimates use finished size, backing overage, and binding perimeter formulas with common U.S. quilting defaults.
Example calculation
A 108" × 108" king quilt has a 432" perimeter before extra binding is added.
Results are planning estimates. Always round up when buying fabric, especially for directional prints, shrinkage, fussy cutting, or cutting mistakes.

Frequently asked questions
Should I use 108 inch backing fabric for a king quilt?
It is often helpful, but backing overage can make the required width larger than 108 inches.
Why does a king quilt need so much binding?
Binding follows the full perimeter, so large square quilts require many WOF strips.
Can this calculator replace a pattern?
No. It gives size and yardage planning estimates, not a quilt pattern.
