Covering Wrap DimensionsBindery Guild
Calculate the size of book cloth, leather, or decorative paper needed to wrap the cover boards.
Hardcover assembly:
Cut two board panels of the board size shown. For the spine strip, cut a vertical strip of grayboard or heavy card stock matching the spine bulk height and spine thickness. Lay out with a uniform 7mm gap gap before gluing.
