Spine Width Calculator

Use our calculator to work out how thick your paperback's spine will be.

To set up your print book cover correctly, you need to know what width your spine will be. Use our calculator below to get a measurement.

1. Select a paper type



2. Enter your page count

This is the page count for your book - you can get it by opening your manuscript in a program like Microsoft Word, where it usually displays the count at the bottom.

Your spine width will need to be: inches

We see your page count is less than 130. Please do not include text or images on your spine, as there will be no room to display them.

Your spine is wide enough for text or images. Please centre these and leave space on either side to prevent the spine detail creeping onto the front and back cover.
