Quilt calculators for blocks, quilts, and yardage
Choose by what you are solving: a whole block, triangle unit, quilt top, or repeated pieces.
What are you trying to calculate?
Which tool should I use?
If the finished block itself is the question, begin with the block size calculator. If you are cutting a particular unit, use the half-square triangle or flying geese calculator. For a whole quilt, start with the quilt size calculator and finish with yardage once the dimensions are settled.
