1. Visual Neuroscience: The 3-Second Window
Online retail algorithms display your book alongside dozens of competing titles. Human brains process visual imagery 60,000 times faster than text. If your cover fails to establish immediate emotional intrigue and clear genre categorization in a tiny thumbnail view, potential readers will scroll past without reading your blurb.
The Thumbnail Litmus Test
Every cover designed by BIGDETAILS OÜ undergoes an 80-pixel thumbnail test to verify that the main focal point and title typography remain distinct and legible on smartphone screens.
