If it does not then you need to adjust your seam allowance (even if the seam itself measures EXACTLY 1/4 inch). In the end it really doesn't matter what the seam allowance is. The only thing that matters is the size of the piece after it is sewn.
exactly my feelings - don't get hung up on actual size of seam allowance the finished size Is what is important - no one sees the seam allowance once the quilt is finished, but they do see the finished size of the blocks
