Frequently Asked Questions
How wide should I cut binding strips?
For double-fold binding (the most common), cut strips 2.5 inches wide. This produces a binding that finishes at about 3/8 inch on the front. Use 2.25 inches for a narrower binding or 3 inches for thicker quilts.
How much binding do I need for a queen quilt?
A queen quilt (roughly 90×100 inches) has a perimeter of 380 inches. Add 20 inches for corners and joining, totaling about 400 inches or 11 yards. This requires approximately 3/4 yard of fabric cut into 2.5-inch strips.
Should I use straight grain or bias binding?
Use straight grain binding for quilts with straight edges — it is easier and uses less fabric. Use bias binding for quilts with curved edges, as the bias stretch allows the binding to curve smoothly.
