If you're working with a designer — or you're a designer yourself — you can follow these guidelines and rules to prepare your PDF of your book.
Cover dimensions
To build your cover to the correct size, you can ask Tablo for a template or create a template yourself with our easy instructions.
Paperback template
To create your own paperback template, you need two things:
Trim size. The height and width you want your book to be.
Spine width. The width of your spine, measured using your book's total page count and its paper settings. Use a formula to calculate your spine width →
Front cover
Width: 0.125″ (3mm) + Trim Width
Height: 0.125″ (3mm) + Trim Height + 0.125″ (3mm)
Back cover:
Width: 0.125″ (3mm) + Trim Width
Height: 0.125″ (3mm) + Trim Height + 0.125″ (3mm)
Spine
Width: (Page Count/PPI) + 0.01”

Hardcover template
To create your own hardcover template, you need three things:
Hardcover type. Digital Cloth with a Dust Jacket or Case Wrap.
Trim size. The height and width you want your book to be.
Spine width. The width of your spine, measured using your book's total page count and its paper settings. Use a formula to calculate your spine width →

To use the formulas, first find the Cover Width and Cover Height for your trim size.

Cover layout
Here's what we recommend for laying out your cover, including the space to leave around certain content, and what areas to pay particular attention to in your design.
Spine text
For spines thinner than 0.35″ (8.89mm) leave a space 0.03125″ (1mm) left and right of your text logos.
For spines wider than 0.35″ (8.89mm), leave a space 0.0625″ (2mm) left and right of your text and logos
Barcodes
All books must have a barcode, which may be put anywhere on the back cover.
Leave a space 1.755″ wide by 1″ tall in your design, and we will place it for you.
Paperback only
Keep text and non-bleed images at least 0.25″ (6mm) from the trim edges.
No spine text for paperbacks books with fewer than 48 pages.
Dust Jacket only
Keep text and non-bleed images at least 0.25″ (6mm) from the trim edges.
Keep important content outside the fold area.
Case Wrap only
Fill as much of the foldover area as you can.
Keep important content off the hinge area.

No bleed. Set the page size to your chosen trim size.
Bleed. Set your page size to your chosen trim size, then add 0.25″ (6mm) to the height, and 0.125″ (3mm) to the width. More on bleed here →
