Quilt Fabric
Estimate total fabric yardage needed for quilt tops, backing, and binding based on quilt dimensions and block size.

Top Fabric = (Rows Needed x Cut Block Size) / 36 yards; Backing = (Quilt Length + 8) / 36 x Widths Needed; Binding = Perimeter / (Fabric Width x 6 strips per yard)
Frequently Asked Questions
How do I calculate fabric for a quilt?
Determine the number of blocks, account for seam allowances, then calculate how many blocks fit across your fabric width to find how many rows you need to cut.
How much extra fabric should I buy for quilting?
Buy 10 to 20 percent extra to account for cutting mistakes, shrinkage, and fabric defects. Pre-wash cotton fabrics as they can shrink up to 5 percent.
What is a standard quilt seam allowance?
The standard quilting seam allowance is one quarter inch. This is smaller than garment sewing which typically uses five eighths of an inch.
