Before I start formatting my book, what is a common/most popular size for a non fiction book? The book is 14 chapters long and will have a number of images in it. The subject matter is creating sacred spaces for meditation and relaxation from a mental health perspective.

Working on the final version of my book cover and I'm going back and forth regarding the weight of the word DEAD. Much appreciated any comment, any feedback before the launch! I'm showing three variants: Version A — STOP and DEAD same size (equal weight, reads as STOP DEAD at a glance) Version B — DEAD smaller (STOP dominates, DEAD recedes) Version C — the hardcover version My concern: does DEAD as a standalone word create resistance when it as big as the word STOP? Tell me honestly: 1. Which version would you click on as a thumbnail? 2. Does the word DEAD put you off, is it a deterrent, or does it create curiosity? 3. Can you tell the genre immediately? 4. Does any version look like a bestseller, and if not, what's missing

I just finished my book page and would like your feedback. It is not yet enhanced for mobile view, therefore it is better to see on the laptop. Also waiting on the final cover design. Thanks for your inputs. https://www.rogermagalhaes.com/book/

How big of a deal is it to pick a title that is already used by a few other books? These other books are not wildly popular. I am writing a book about digital addiction and how to help your child. The title I might use is Left to Their Own Devices: Six evidence-based approaches to help your screen-addicted child. The other books have different subtitles from mine. If that is a really bad idea, what about this title Screen Time Rescue: Understanding Your Child's Digital Addiction and How to Help Their Brain.

What about this title, if the goal is conversion (using plain language) and having strong keywords on the back end? I'll put another option in the comments
