Spine & Weight Calculator
For your book’s spine width, use our calculator and determine the book weight as well as print margins.
Although Rapido Books make every effort to adhere to your specifications, our printers have a minor variation factor of 0-1 mm.
– Keep a safe zone of 5 mm or 1/4 inch text-free to prevent “bleeding” (having text cut off);
– If you want one or more images up to the cut, please include a bottom margin to avoid a lost white border on the edge of your page. The bleed must be at least 3 mm or 1/8 inch.
