Spine & Weight Calculator
For your book’s spine width, use our calculator and determine the book weight as well as print margins.
Step 1: Tell Us about Your Book
Step 2: Calculate Your Book’s Spine Width & Weight
Step 3: Check Your 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.
