Even though we\u2019re not supposed to judge a book by its cover, we do it all the time. Covers are our first impressions, and they give us a peek into the world we\u2019re about to pull from the shelf. Same goes for the book\u2019s spine. When we browse a bookstore or library, we\u2019re usually only seeing the spine, sandwiched between other books on a packed shelf. So it\u2019s important to get the spine right in many ways. This post will delve into how to calculate book spine width, as well as discuss ways to make your spine stand out in a sea of other stories. <\/p>\n\n\n\n

Why is the Spine Important?<\/h2>\n\n\n\n

Do not underestimate the power of a spine. A spine width is the total of the number of pages the book includes, their thickness, and the thickness of the covers. If you tweak any of these factors and carefully design the imagery and text, you can ensure that your spine stands out.<\/p>\n\n\n\n

How to Supercharge Your Spine<\/h2>\n\n\n\n

Relatively small changes that don\u2019t affect the quality or design of your book can help make it significantly more marketable. Consider these tweaks to increase your spine size:<\/p>\n\n\n\n

Bump Up Text Size:<\/span> If you increase the size of the text in your book, you will also increase the size (and thus the spine width) of the book. It will make your text more readable, but it will also make the book more expensive to print\u2014so weigh this option carefully.. Per our earlier blog on book publishing, What are the Standard Book Sizes in Publishing?<\/a>, you\u2019ll see how publishers walk the line between book size and budget.<\/p>\n\n\n\n

Increase Paper Thickness:<\/span> An easy way to enhance the size of your book is by choosing paper with greater thickness. Thicker paper also bolsters the durability of the book and gives it a great, tactile feel that is both luxurious and interesting. Again, you\u2019ll need to consider the cost implications of making this change.<\/p>\n\n\n\n

Designing the Spine<\/h2>\n\n\n\n

Once you\u2019ve calculated your spine width, make sure you carefully consider the design of the spine. Your text needs to read from top to bottom to follow a natural progression of reading. It can run straight down the spine or (most often) it can be at a 90 degree angle so that the top of the text points to the right. A larger spine can even feature the words running right across it like natural text, in the example below.<\/p>\n\n\n\n

If there is a main title and a subtitle, the main title will go above the subtitle. The spine also usually includes the author (and illustrator if there is one) name and the publisher or publisher logo. These elements will be horizontally centered across the width, with a space of at least 1\/16 inches between the text and the spine edge, to ensure that it stays on the spine and does not migrate to the front or back covers. If the book\u2019s spine is .15 inches or less, it may not include text to avoid this issue.<\/p>\n\n\n\n
