Your book cover thumbnail must compete for attention in Amazon search results at just 160 pixels wide.

Fiverr KDP cover designers who specialise in puzzle books deliver properly formatted files from $25 to $65.

• Thumbnail clarity at 160px more important than full-size beauty
• Bold high-contrast colours perform best for puzzle books

• BookBolt identifies exact buyer search phrases for puzzle books
• Title must include primary keyword naturally and clearly
• Subtitle covers secondary keywords and target audience
