Improper formatting is the number one reason self-published manuscripts get rejected by Amazon KDP UK or print with misaligned margins. Follow this essential design checklist to ensure a professional finish.
Popular UK paperback trim sizes include 5" x 8" or 6" x 9" for non-fiction and memoirs, and 5.06" x 7.81" (B-format) for UK fiction paperbacks.
Ensure interior gutter margins are set between 0.375" and 0.5" depending on page count so text does not disappear into the book binding.
Book covers must be designed at 300 DPI resolution in CMYK color mode with spine width calculated based on exact interior paper stock weight.
