According to Createspace’s submission requirements,
To calculate the spine width of your book,
- White paper: multiply page count by 0.002252
- Cream paper: multiply page count by 0.0025
So, for the 230 page cream book I’m working on, my calculator says the spine width should be 0.575″. That’s also what Createspace is telling the author, as it rejects the cover I made for her.
Why the rejection? Because instead of painstakingly measuring the spine and adding it in separately to the front and back, I just use Createspace’s automatic cover generator.
But Createspace won’t let me make a cover for 230 pages. They either round it down to 224 (0.56″ – the same as my original book cover, when I still trusted Createspace and hadn’t noticed the discrepancy) or up to 234 (0.59″ spine).
It seems Createspace needs to automatically add a set number of pages – which is fine, but if those pages are added into the manuscript directly for printing, then my cover should have worked fine.
Instead, Createspace responded saying the spine needs to be exactly 0.575″ (the proper, calculated spine width for precisely 230 pages). Either someone at Createspace doesn’t know what’s going on, or the automatic generator is flawed beyond usefulness.
