Enter your quilt size, block size, and fabric width into the calculator to determine your fabric needs.

Fabric Calculation Formula

The following formula is used to calculate the amount of fabric needed for your quilt.

Fabric Needed = (Blocks Per Length * Block Size) / 36

Variables:

  • Fabric Needed is the amount of fabric required (yards)
  • Blocks Per Width is the number of blocks that fit across the fabric width
  • Blocks Per Length is the total number of blocks required for the quilt length
  • Block Size is the size of each block (inches)

To calculate the fabric needed, determine the number of blocks that fit across the width of the fabric, then calculate the total number of blocks required for the quilt length. Use the formula to determine the
