Quilt calculators for blocks, quilts, and yardage

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.

Every calculator follows the same rules as the block cutting charts. Each one either gives a complete answer or says plainly why it cannot, and a size that cannot be cut on a ruler is refused rather than rounded. The arithmetic runs in your browser, with no account or sign-up.

Need the vocabulary or the measurement rules first? Continue to the guides directory for the reference pages that explain finished size, seam allowance, printing, and squaring up.
