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:

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

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. Look up your spine width in our tables →

Dust Jacket

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.

Interior dimensions

Set the page size to your chosen trim size, plus bleed (if any).

  • 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 →

Interior layout

Keep important content at least 0.5″ (12mm) from the edges of your pages. More on margins here →

Page count

  • Make your final page count an even number.

  • Our minimum page count is 18, including blank and unnumbered pages.

Font

  • Embed fonts in your PDF. Our printer can only see and reproduce your fonts if they have been embedded.

Images

  • Images will print best if they are 300 PPI at the size you need.

  • We cannot print images below 72 PPI.
