Adventures in Self Publishing – Mistake #3 – Back to book covers.
Last week I introduced you to the FABULOUS Mark Swan at kid-ethic who kept me sane through all the blunders I made. Have a look at his beautiful covers HERE.
A few things you might find it useful to know.
- DO NOT try to design a book cover yourself. Find, and pay, an experienced professional.
- E-book covers are relatively easy to upload. Dangerously easy.
- Paperback covers are many orders of magnitude more difficult to get right. There are spine widths and bleed and PPI’s and other things sent to confound you.
- Whatever you do ALWAYS PAY FOR A PRINT PROOF before you order any serious number of books.
- Print on Demand (POD) means more variability.
- You’ll be glad of professional help.
e-book
On all the platforms e-books are made really easy for you. Upload a cover image (.jpg accepted by most) and your book cover is ready.
Easy! Or too easy? Dangerously easy.
To get a good-looking book cover, it’s not enough to have the right illustration, information and typeface, you also need it in the form of a good quality image with a size ratio of 1 (width) to 1.6 (height). If you use different dimensions, each platform will either crop or distort the picture.

Paperback
The paperback cover is a bit more complicated. How on earth do you choose the book size?
First thing to learn is it’s called the trim. Multiple pages are printed on rolls of paper and then cut (or trimmed) to the specified size. Within limits, the larger the book – the fewer the pages and the lower the cost of print-on-demand.
Inches | mm | |
A – format | 4.4 x 7 | 111 x 178 |
B – format (USA) | 5 x 8 | 127 × 203 |
B – format (UK) | 5 x 7.8 | 129 x 198 |
A5 | 5.8 x 8.25 | 148 x 210 |
Trade format (USA) American Royal | 6 × 9 | 152 × 229 |
Many UK trade paperbacks are UK B format, but most self-publishing platforms have a US Bias, so I opted for a single size available across the platforms which was closest to the original Sandstone Press edition of my book.
Bookshops, for understandable reasons, don’t like buying from their greatest rival, Amazon, so I selected Ingram Spark a printer who could supply Gardners in the UK who in turn supply bookshops.
I selected 5” x 8” trim, black and white on crème paper inside , with a full colour cover in a matt finish.
With a single trim, I thought I’d only need a single cover design across all platforms.
Think again:
Here’s where I really tried the patience of the saintly Mark Swan at kid-ethic.
For the same book, of the same size, with the same number of pages, I needed a slightly modified design for each platform.
Spine Width | |||
mm | inches | Other | |
KDP | 18.92 mm | 0.745 in | |
Barnes & Noble | 17.018 mm | 0.67 in | NO BARCODE ALLOWED |
Ingram Spark | 17.12 mm | 0.67390 in | Max 600 PPI image |
I’m not quite sure what I did wrong with Barnes and Noble, but they wouldn’t let me use the same ISBN (unique identifying number) that I’d used for KDP and Ingram Spark, so I had to release another of my precious numbers. I’ll need 17 full price sales from B&N to cover that – sales to date with B&N – ZERO.
Ho hum.
And I’m still wrestling with Ingram Spark, although a wonderful human being called Clair is helping me and is a welcome change from the infuriating chatbots on other platforms. The Ingram Spark computer says NO every time I load the cover (even through it meets all their stated requirements), and when I took the plunge and ordered a proof, it arrived with unequal borders.


To conclude – the one blunder I didn’t make was to try to design my own book cover. My talent starts and stops with elaborate doodles and I never considered doing this part myself. However – even if I possessed the talent and experience to get that part right – what I hadn’t realised was quite how much other technical stuff is involved – sizing, colour density, bleed, margins, borders, dots per inch, file size…
What I learned: self publishing doesn’t mean doing everything yourself. Know your limits and pay for professional help. It may save your sanity…
You can buy Phosphate Rocks: A Death in Ten Objects from Drake the Bookshop in Stockton UK – the only bookshop who currently have stock of the new design. Also available from Barnes and Noble, Kobo, and You-know-Who.
Pity sales are still sales…
