More KDP rules

• KDP margins and gutter for puzzle books

  The inside margin grows with the page count so text is not lost in the binding.

• KDP spine width and cover size

  The spine is the page count times the paper thickness, and the cover is front, spine, back and bleed.

• KDP page count limits by trim and paper

  Minimum and maximum page counts depend on trim size, paper and ink.

• KDP fonts, lines and image rules

  Small details that cause rejections: unembedded fonts, hairlines and pale greys.
